Four .45 ACP Revolvers

By Joe Berk

When most folks think of the .45 ACP cartridge, they think of the 1911 and other semi-auto handguns.  The big .45 also makes an ideal wheelgun cartridge, especially in N-frame Smith and Wessons.  I own four (the ones you see above) and I shoot them all.

The .45 ACP Revolver Story

Smith and Wesson forayed into the .45 ACP revolver business when Colt couldn’t keep up with the demand for its 1911 semi-auto in World War I.  The Army asked both Smith and Colt to make .45 ACP versions of their large-frame double action handguns, both manufacturers did, and the Army designated both revolvers as the Model 1917.

After the World War I, the 1917 revolvers became available to civilians.  Colt left the .45 ACP revolver business, but Smith and Wesson soldiered on, and to this day Smith still offers several different models.

Shooting .45 ACP ammo in a revolver requires a clip.  You have to snap the rounds into the clip so they will fire and extract in a revolver.  At one point, the 1917 revolvers were popular enough that Remington introduced the .45 AutoRim cartridge, which is a rimmed version of the .45 ACP that allows use of the cartridge in a revolver without the clip.

.45 ACP rounds in a star clip. I have a tool that makes it easy to insert cartridges in the clips and remove the empty cases after shooting. In World War I, clips held only three rounds (you needed two to load six rounds in a 1917 revolver).
A .45 ACP round (left) and a .45 AutoRim cartridge (right). Note the difference in rim configuration at the base of each cartridge.  I’ve experimented with both ACP and AutoRim brass in my .45 ACP revolvers; both deliver comparable accuracy.

Over the years Smith and Wesson has manufactured several .45 ACP revolver models.  I’d like to own them all, but there’s only so much room in the safe and Susie’s willingness to indulge my gun collecting.  The four this blog addresses are:

      • The Model of 1955
      • A Jovino snubnose
      • Smith’s reincarnated and Turnbull-finished Model 1917
      • The Performance Center Model 625.

Info on each follows.

The Model of 1955

Smith introduced the Model of 1955 as an alternative to the 1911 semi-auto for bullseye target competition.  Mine was made in the 1970s.   I bought it from Rutgers Guns in Highland Park, New Jersey shortly after I left the Army (Rutgers Guns had no connection to Rutgers University other than geography).  I paid around $200 for it new.

A typical Model of 1955 three-shot 50-foot group. This gun shoots everything well.

The Model of 1955 has Smith and Wesson’s target trigger and target hammer, and it has target sights (with a Patridge style sight in front).  It originally had checkered grips, but shortly after I bought it I put a set of smooth grips on it.  I think the smooth grips both look and feel better.  Back in the day, you could purchase those grips new for around $25.  Today, a set from that era (like the ones you see above) would fetch $300 to $400.  The Model of 1955 has the highly polished and deep blue finish that is the hallmark of earlier Smith and Wesson revolvers.  It is a beautiful handgun.

I never tried a load in the Model of 1955 that didn’t do well; every powder and every bullet combination I loaded grouped well.  In the nearly 50-years that I’ve owned this revolver, I’ve only seen one other guy on the range with the same gun.  I asked him what load he used and he told me the gun likes everything; every load he ever tried shot well, too.  That said, the load I use is typically 4.2 grains of Bullseye and a 200-grain semi-wadcutter bullet.  I use Lee’s Deluxe 4-die set and I crimp the bullets with their factory taper crimp die to assure easy chambering and to prevent bullet pull under recoil (although recoil with this load is light).

The Jovino Snubbie

The Jovino snubnose revolver is a rare animal, one of 650 customized by New York City’s John Jovino Gun Shop (which no longer exists; when it closed, Jovino was the oldest gun shop in the country).

The Jovino snubnose .45 ACP revolver. It’s a real rarity.

Back in the 1980s, Jovino’s built custom guns.  Their main clients were the NYPD and other police departments, so many of the Jovino customs tended to be duty-oriented carry weapons.  Jovino bought 6 1/2-inch barreled Smiths like the one you see above and turned them into 2 1/2-inch snubnose revolvers. The conversion was not just a simple chop job, though.  Here’s what Jovino did to these guns:

      • Shortened the factory barrel to 2 1/2 inches.
      • Installed a crane lock to replace the ejector rod lock.
      • Relocated the red ramp front sight.
      • Rounded the butt to the S&W K frame round butt configuration.
      • Tuned the double and single action trigger.
      • Radiused the hammer spur.
      • Polished the trigger face.
      • Fitted Pachmayr rubber grips.
      • Reblued the cut barrel (the new bluing is actually a bit darker and more polished than the stock bluing).

The original grips that came with the Jovino snubbie were rubber Pachmayrs, but I wanted the look of ivory grips. That’s when I found out that the Jovino guns did not have a standard N-frame rounded grip profile.  It took a lot of patient sanding and polishing to get the fake ivory grips to fit.  I like the look.

The grips look good. So does the revolver. One of the Jovino custom touches was to round the hammer spur profile. I like what they did.

The double action trigger on the Jovino is incredibly smooth.  The slick trigger and the red ramp and white outline sights work together well, and the gun is very accurate. I’ve never seen another one of these guns on the range, so the exclusivity factor is there, too.

Smith and Wesson’s Reincarnated 1917

Smith’s resurrected Model 1917 .45 ACP revolver, shown here with AutoRim ammo.

About 20 years ago Smith and Wesson introduced a reissue of its World War I Model 1917 for a very short time, and as part of that deal, the new Smith included Turnbull color case hardening.  I saw one of the Turnbull 1917 revolvers at a local Bass Pro and it sat in the display case for months.  Bass Pro had it marked down to $695 and it still hadn’t moved.  I asked the kid behind the counter what they would take for it; he read the price tag and told me $695.  Would you consider less, I asked.  I’d have to ask the manager, he said, looking at me and not moving.  Why don’t you do that, I answered.  He finally realized his job was to sell stuff and I was a real live customer, so he took off in search of the boss.

“We’ll take 30 off,” Junior said when he returned.

“Is that percent, or dollars?” I asked.

He smiled.  “Dollars.”  It was still a hell of a deal, so I pulled the trigger.  Today if I wanted to sell this gun I could probably get $1500 for it.  But I don’t want to sell it, and I never will.

Another view of the 1917, its glorious Turnbull color case hardening, and .45 ACP ammo loaded in clips.

I don’t shoot my Turnbull 1917 all that often; my preference is the Model 625 described below.  The 1917 groups well, but its small checkered grips are punishing.  This is another cool gun.  I’ve never seen another one on the range.

Smith’s Performance Center Model 625

The Performance Center is Smith’s marketing shtick for guns that have been slicked up a bit, which is Smith and Wesson’s way of saying they build Performance Center guns with the attention to detail that used to be standard on all Smith and Wessons.  This one has a good trigger, a different barrel contour, blended edges on the front of the cylinder, and probably a few other niceties I can’t remember right now.

This revolver originally had clown-like, awkward, red-white-and-blue grips.  I quickly swapped the goofy factory grips for what were advertised as rosewood grips from a third-party vendor (they weren’t rosewood at all; they were instead fabricated of cheap laminated and dyed wood, as I found out when I refinished them).   But my custom grips fit my hands much better, and this is an extremely accurate revolver.  I also installed a red ramp front sight and a white outline rear site.  The white outline rear sight Smith sells today has barely-visible gray lines and the red is not as bright as it used to be, but they are better than the gold dot front sight and plain black rear sight that came on the gun (I don’t like gold dot front sights).

Six rounds at 50 feet, standing, from the Performance Center .45 ACP Model 625.  This revolver has grips I refinished and a red ramp and white outline set of sights.  The target shown here was shot with the 200-grain semi-wadcutter bullet and 6.0 grains of Unique.

My usual accuracy load for the 625 is a cast 200-grain semiwadcutter bullet (sized to .452 inches) over 4.2 grains of Bullseye.   Another load that works well is the same bullet with 6.0 grains of Unique (it’s the load I used on the target above).


After reading about the above Smith and Wesson .45 ACP revolvers, you might have two questions:

      • Which is my favorite?
      • Which do I prefer:  A .45 ACP revolver or a 1911?

The answer to both questions is:  Yes.

Gats and Hats II: A Jovino Model 25

The revolver you see in the blog today is a rare animal, one of 650 customized by New York City’s John Jovino Gun Shop.  I guess the best way to start this post is with the John Jovino story.  The Jovino Gun Shop is no longer in business, having fallen victim to the Covid 19 pandemic, but until then it was the oldest gun shop continuously in business in the entire country.  John Jovino opened the store in 1911; he sold it to the Imperato family in the 1920s (the Imperatos are the folks who started and now operate Henry Firearms). Jovino’s was famous and it’s been in more than a few movies (and even in my favorite TV show, Law and Order).

The John Jovino Gun Shop in Manhattan, said to be the oldest gun shop in both New York City and the United States. Unfortunately, it is no longer in business.

Back in the 1980’s, Jovino’s built custom guns.  Their primary clients were the NYPD and other police departments, as well as individual police officers, so many of the Jovino customs tended to be duty-oriented carry weapons.  The one you see here is no exception.  Jovino’s started with 6.5-inch-barreled Model 25 Smiths chambered for the .45 ACP cartridge and they turned them into 2.5-inch snubnosed revolvers.  The conversion from a stock Smith and Wesson Model 25 to a Jovino snubbie, though, was not just a simple chop job.  Here’s what the wizards at Jovino did to these guns:

      • Shortened the factory barrel to 2.5 inches.
      • Installed a crane lock to replace the ejector rod lock.
      • Relocated the red ramp front sight.
      • Rounded the butt to the S&W K frame round butt configuration.
      • Tuned the double and single action trigger.
      • Radiused the hammer spur (you can see it in the photos).
      • Polished the trigger face (you can see that in the big photo at the top of this blog).
      • Fitted Pachmayr rubber grips.
      • Reblued the cut barrel (the new bluing is actually a bit darker and more polished than the stock bluing).

As you probably already know (and you certainly know if you follow the ExhaustNotes blog), the 1917 platform Smith and Wesson and Colt revolvers can fire .45 ACP ammo if the cartridges are mounted in clips, or they can fire .45 AutoRim ammo.  .45 AutoRim ammo is essentially the .45 ACP cartridge with a rim.  For this test series, I used reloaded .45 AutoRim ammo.  It’s the ammo you see in the photo below.

A gat and a hat, with six rounds of reloaded .45 AutoRim ammunition.

The original grips that came with the Jovino Model 25 snubbie were Pachmayrs, and they probably make more sense (more on that at the end of this blog).  I didn’t care for the appearance and for reasons it would take a therapist to explain, I wanted ivory grips (I think it has something to do with watching Patton too many times).  I settled for fake ivory, which provided the look I wanted without the cost.  Don’t tell the General.

The Pachmayr grips that originally came on the Jovino Model 25 snubbie.
When Jovino cut the Model 25 barrels down to 2.5 inches, there wasn’t enough room left in the ejector shroud for the front cylinder lock, so Jovino incorporated the ball-detent cylinder lock you see in this photo.

When the new grips arrived, I liked the S&W escutcheons and I liked the look, but I didn’t like the fit.  I didn’t realize what I had in the Jovino and the extent of the customization that went into these guns.  I ordered grips for an N-frame round butt Smith and Wesson, but they stood a bit proud on the revolver’s grip frame (the back strap).  That’s because the Jovino customs reworked the frame from a square N-frame grip profile to a Smith and Wesson round butt K-frame profile, but I’m told the K-frame grips won’t match exactly, either.  I bought the larger N-frame grips figuring I could take grip material off, but I couldn’t put it back on.  I didn’t dare attempt to sand the grips on the gun, so I very gently went to work on them with sandpaper off the gun, repeatedly installing and removing the grips to take off just enough material to get a good grip-to-frame match.  When I was just about there, I found that by stepping down to 400, then 600, and then 800 grit sandpaper, I could match the polished look on the rest of the grip.  I was pleased with the result.

The grips look good. So does the revolver.  One of the Jovino custom touches was to round the hammer spur profile.  I like what they did.

I tested three .45 AutoRim loads:

      • A 200-grain Speer swaged semi-wadcutter bullet loaded with 4.2 grains of Bullseye.
      • A 200-grain Precision Cast semi-wadcutter bullet loaded with 6.0 grains of Unique.
      • A 233-grain Missouri K-Ball cast roundnose bullet loaded with 5.6 grains of Unique.
.45 AutoRim ammunitiion. Note the rim on the brass cartridge case. The case is identical to .45 ACP ammo in all other dimensions. From left to right, you see the 200-grain swaged Speer semi-wadcutter bullet, the 200-grain Precision Cast cast semi-wadcutter bullet, and the 233-grain Missouri Bullet cast roundnose K-Ball bullet.

I had already tested my Jovino revolver for accuracy at longer distances a few years ago; this test was to be different.  Like the .38 Special Model 60 accuracy tests we wrote about a couple of days ago, I set up a few “Betty and the Zombie” targets at 7 yards and I fired double action as quickly as I could.  I’m told the typical hostage rescue zombie gunfight occurs at 7 yards, so I wanted to get a feel how I would do in these encounters.  You know, so I’d be ready.

What was surprising to me was just how incredibly smooth the double action trigger was on the Jovino.   In a word, it’s amazing.  Shooting double action was fun.  The slick trigger and the Model 25 Jovino’s red ramp and white outline sights seem to glue the front sight to the zombie’s left eye, until that part of the zombie disappeared and I was shooting at a hole. These guns are impressive.

The 200-grain semiwadcutter with 4.2 grains of Bulleye was a very pleasant load (for me, not the zombie) with modest recoil.  The 233-grain K-Ball Missouri load was a much more emphatic load.  That one pounded me around a bit more, but it still hung in there on the zombie.  All of the loads shot essentially to point of aim.  Each of the targets below were hit by five full cylinders of .45 ammunition, or 30 rounds apiece.  There was not a single miss among all 90 rounds.

Zombie versus .45 AutoRim ammo loaded with 200-grain Precision Cast bullets and 4.2 grains of Bullseye.
200-grain Speer bullets and 6.0 grains of Unique. Sometimes zombies don’t go down with the first shot, so I lobbed in another 29.
Betty was plenty nervous, but she held still. The zombie did, too. He took 30 rounds of 233-grain K-Ball Missouri bullets propelled by 5.6 grains of Unique.

So what’s the bottom line to all of this?   The Jovino .45 ACP revolver is accurate, it has a superb trigger, and it is just plain fun to shoot.  That last load was a bit much.  The 233-grain K-Ball Missouri looks pretty much like their 230-grain roundnose, but the difference in recoil is both perceptible and significant.  You can go quite a bit hotter with this load, but I won’t.  When I finished shooting, I was surprised to see I had done a bit of damage to my thumb.  I think it happened on the last round or two because there’s no powder residue where the skin tore away, and it happened because the faux ivory grips have a bit of a corner to them.  The rubber Pachmayr grips wouldn’t have done this, but they don’t look as cool as the grips the Jovino wears in these photos.   The gun doesn’t do this firing single action, but I guess my hand rode up a bit firing double action.  Sometimes these things happen when you take on the odd zombie or two.

Zombie combat. It’s a tough job. Somebody’s got to do it, though.

The Jovino Model 25 is probably the finest and smoothest revolver I’ve ever shot.   It’s a keeper.
