45 Colt New Service (by Guy Miner)

Good buddy Guy Miner, former US Marine and retired law enforcement officer, enjoys following the ExhaustNotes blog and in particular, our gun stories.  Guy has a very cool 1909 Colt and he wrote a guest piece on it for us.


Pressed into service by the Army, Navy and Marines early in the twentieth century, the Colt New Service revolver also served in various police departments and of course as a sturdy handgun for many outdoorsmen. This particular revolver was my grandfather’s and I’ve been caring for it the past 35+ years. The old Colt is a big revolver, with a 5 ½” barrel and those gaping 45 caliber holes in the cylinder. Grandpa, a WWI veteran, got this Colt after it was sold as surplus by New York. The backstrap is marked NYST for New York State Troopers. He carried it as part of his WWII era security duties with the Home Guard.

When it became mine, I replaced the bulky custom grips that fit the frame poorly and my hand worse. A pair of recent manufacture, original looking grips better suit both the revolver and my hands. I wasn’t expecting much in the way of accuracy and was pleasantly surprised on my first trip to the range with it. The first ammo I used was Federal’s 225 grain LSWC hollow point which produced modest recoil and good accuracy.

All of the major ammunition makers support this wonderful old cartridge. It was originally a low pressure, big bore tossing a heavy lead bullet at modest velocity. For this revolver, that’s exactly how I load it. Typically I’ll use the soft swaged 250 grain Speer LSWC loaded with 8 grains of Unique and a CCI 300 primer for about 830 fps.

One caution when loading for these fine old revolvers – they’re not meant to handle the very stout 45 Colt loads intended for use in Ruger’s much newer and stronger revolvers. Stick with loads for the old 45 Colt, which approximate the power level of a 45 ACP.

I treat the old gun gently, shooting only a few boxes of ammo through it every year. Now and again I’ll shove it into a holster and haul it along with me on a camping or fishing trip, though I prefer a smaller revolver for those duties. Mostly it gets hauled along out of a sense of nostalgia. Handling it, I can’t help but think of my grandfather, of the trooper who carried it long ago, and of the history wrought by these grand big bore revolvers.


Guy, thanks very much for your guest blog.  I always enjoy reading about vintage revolvers.  Your Colt has an interesting provenance and a great family history, and the grips you put on it look great.  I always wanted a 1909, and your story makes me want one even more.  You write well, my friend.
