A few years ago, I had one of the Kahr Thompson "Commando" models (Parkerized M1927A1 models with blackened furniture and a horizontal rather than vertical "pistol-gripped" handguard that frustrated me to no end. It was a real "jam-o-matic" that I eventually got rid of.

Well, the bug was still biting me, so I inexplicably ordered a new Kahr M1A1 model from Bud's gunshop. Fearing the worst, I took it to the range for the first time today and am thrilled at the results! I fired 150 rounds today, 100 of which were home-cast 230gn. RN reloads with zero malfunctions. Accuracy was splendid: I was hitting rocks and other debris no bigger than six inches in diameter with monotonous regularity at 200 meters. Mind you, there was at least a quarter second delay from trigger pull to impact, but that made it all the more fun.

Given the low cost of .45 ACP vs. 7.62 X 51, (especially when I'm reloading home-cast projectiles) I can predict that this carbine will be plinked with quite a lot this year. And with its light recoil, I wouldn't discount its practicality vis-a-vis home defense. The ability to put 30 rounds of 230 gn. .45 cal. ball into a torso-sized target at well over 25 meters as rapidly as one can pull the trigger is pretty effective firepower by any measure. Because of today's success, I'm even contemplating submitting a form 1 application and making this an SBR so it will look more authentic and be more handy.

I don't know if there is a major machining difference between the feed "ramp" contours of the 1927A1 and the M1A1 models, but I noticed a pretty big variation between this M1a1 and my old 1927A1 "commando" model of years past. On the "commando" model, my jams were almost certainly related to the geometry of the feed "ramp" area (see attached photo). There were two angles--a wider one followed by a narrow funnel into the chamber. Many of my rounds would jam perpendicular to the chamber, and brass smears on the breakover point between the two "feed ramp" angles suggested that this contributed to the jams. On this M1A1 model, I noticed that the "feed ramp" was simply a large funnel with no intersecting areas. Perhaps this is an improvement instituted by kahr. I may never know.....What I do know for certain is that this carbine is a classic-looking firearm that has performed splendidly so far. If this is typical of new production Kahr "Semi-auto Thompson sub-machine guns", I encourage everyone who's ever wanted one to buy with confidence.
