I find it very difficult to shoulder my Kahr M1 Thompson. The buttstock length is too long (called the length of pull?) I replaced the Kahr stock with a military stock and it fit me only slightly better. I think another 1/4" shorter would fit me better. I've never had this problem with any of my rifles. Anyone else with the same problem?

Your arms are too short! I suspect it is more of a problem with Thompsons utilizing a horizontal foregrip, as you have to reach a tad further forward with the left hand. My dad, however, has a lot of trouble shouldering the 1928 with a vertical grip. He says it is "too long". Don't know what you can do really. I suppose a compentent woodworker could shorten the rear of the stock and reshape the buttplate.

With my Kahr I got the 1928 buttstock conversion, It looks good and the stock is removable and with the right milling on the frame it looks even better. in fact I recommend the milling to the frame to sit the stock closer and more TSMG appealing. All in All the stock is shorter and you could place it closer if you wish I think I remember 2- 2 1/2 less than the M-1 style. Hope this helps-adlake

Now, I just knew somebody would say I had short arms and it gave me a good laugh when I saw the first reply to this post . I don't want to beat this to death but I measured my FAL and another rifle of mine for the length of pull. They measured 13-1/2 to 14-1/2 inches. The Thompson measured a full 17 inches.

My arms always looked normal to me but now I..just....don't know. blink.gif

smile.gif I just went and measured mine, 16 3/4 on my GI M1A1 lower for my dummy, 16 5/8 on my W/H 28
cool.gif There is a lot more drop than most modern shooters are used to. I've always loved the buggers, I think most factory stocks are short. I take a 16 1/4 on my custom rifles or that's what my gunsmith fitted me out at.
Course they gave me the nickname Big Boy at work for a reason....

Jeez Bisley, you must be a giant! 13.5 is “normal” pull for a sportier. I’ve set up a few for guys like you, most have crescent moon scars over their eyebrow and crooked noses form shooting “regular” rifles. To a man, when you get them into a proper fit they are so much happier; it’s like a new sport to them.

You have to shoot the Tommy “heads up”. Feels good to me!

I made a custom stock out of scrap wood. I used the G.I. butt plate and attach slide (1928). The stock is now about 2" shorter, it fits just fine. I'm 5'4" and I find most stocks are too long. All my shotguns and most rifles are cut down. It sure feels better when it fits biggrin.gif

I've made two stocks using old Garand stocks. One has the same length of pull as the regular 28 TSMG stock the other one is 2" shorter. One of the nice things about using these stocks is with a good cheek weld you are looking through the sights instead of at the back end of the recoil spring pilot.
