.45 AutoRim – The ExhaustNotes Blog

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.

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.

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.

Reloading .45 ACP for 1917-style revolvers.

When I first posted about the Model 60 load development plan and the Altamont grips I bought from good buddy Paul, the cover photo showed my recently-acquired Model 60 snubbie and a Smith and Wesson Performance Center Model 625 I’ve owned for years.

I like that photo because the two stainless steel Smiths look great on the wild boar skin. That skin is from a pig hunt Paul and I did in Arizona a few years ago.

The earlier blog was about finding an accuracy load for the Model 60, but a few people wrote to ask if I had a favorite load for the Model 625. I do: My usual accuracy load for the 625 is a cast 200-grain cast semiwadcutter bullet (sized to .452 inches) over 4.2 grains of Bullseye.

When I went to the range to run a few rounds through the 625 I picked a box of ammo I had reloaded in 2014. It was different than my usual accuracy load. I used the same bullet (a 200-grain cast semi-wadcutter), but instead of Bullseye I had loaded these over 6.0 grains of Unique. And instead of .45 ACP brass in star clips, I used AutoRim brass. This is the load I fired that 6-shot group you see in the cover photo above for this blog, and it’s a honey. The group, that is…not the photo (it’s hard to get true colors when using an iPhone in the shade). I shot at 50 feet while standing…there’s no rest for the Model 625 or the weary.

.45 ACP cartridges in star clips for the Model 625. These are loaded with 230-grain cast roundnose Missouri bullets.

The .45 ACP cartridge (left) and the .45 AutoRim cartridge (right). The AutoRim cartridge is designed for use in the Model 625 without star clips. The ACP cartridge has a 230-grain roundnose Xtreme bullet; the AutoRim cartridge has Missouri’s 200-grain semi-wadcutter.

The AutoRim brass is in the tumbler as I write this and when I reload it I’m going to go with the same load: The 200-grain cast semi-wadcutter over 6.0 grains of Unique. It seems to be working for me.
