Deputy Posted May 26, 2006 Report Share Posted May 26, 2006 (edited) After reading the suggestion from TommyGunner, I went to work on my 1927A1. The problem was it WAS cocked and wouldn't fire. This meant I couldn't dissassemble it either. TommyGunner (Damon) suggested I pull the cocking knob back and play with the trigger. I hooked the knob on my wooden workbench and pushed down. I am fairly strong, but the recoil spring on the 27A1 must have been made for Godzilla http://www.machinegunbooks.com/forums/invboard1_1_2/upload/html/emoticons/ohmy.gif Anyway, with the knob in the rearmost position, I squeezed the trigger repeatedly. Nothing seemd to be happening. So I eased the knob forward and tried it again. Still nothing. So I let the cocking knob ease forward and put the barrel of the rifle on a small piece of carpet. Then I tried pushing with both thumbs on the trigger to see if I could move it forward. I heard and felt a distinct "CLICK" when I did this. I curled my index finger around the trigger and cautiously applied tension to the trigger. There was DEFINITELY resistance felt. More tension and "CLACK". The hammer fell to the fired position. LOL...I let out an "OH YEAH" yell that woke up all my neighbors http://www.machinegunbooks.com/forums/invboard1_1_2/upload/html/emoticons/laugh.gif I pushed in the takedown button on the rear of the receiver, and what was previously under heavy spring tension was now completely free. I can slide the upper and lower apart with ease. My thanks go out to TommyGunner (Damon) for his expertise and helpful suggestions. Sure saved me from shipping that beast back to Kahr and getting reamed out for a service charge that wasn't even my fault. I suggest the mods add this fix to the FAQ. It will save a lot of future headaches for anyone who had the same problem I had.

SecondAmend Posted May 26, 2006 Report Share Posted May 26, 2006 Congratulations and better luck in the future with the operation of your Thompson. Kudos to Damon. Link to comment Share on other sites More sharing options...
Deputy Posted May 26, 2006 Author Report Share Posted May 26, 2006 Thanks SA. Next I take it apart and see if I can find any parts that might be bent or broken. http://www.machinegunbooks.com/forums/invboard1_1_2/upload/html/emoticons/tongue.gif Dep Link to comment Share on other sites More sharing options...

Norm Posted May 27, 2006 Report Share Posted May 27, 2006 Deputy, Damon is good guy; you should check out his web-site for Thompson goodies and parts! http://www.machinegunbooks.com/forums/invboard1_1_2/upload/html/emoticons/wink.gif I had a 27A1 that did the same thing yours did. It happened to me several times. http://www.machinegunbooks.com/forums/invboard1_1_2/upload/html/emoticons/banghead.gif I finally found out why; the rear grip screw was protruding to far into the trigger frame. The sear would come down and contact the screw (while pulling the trigger.) I put some washers between the screw head and the wood of the rear grip- problem solved. This happened because WH grips were made to sloppy tolerences and mine just happened to have the hole drilled too deep. You may want to check this on your gun. Enjoy your gun! http://www.machinegunbooks.com/forums/invboard1_1_2/upload/html/emoticons/cool.gif Norm Link to comment Share on other sites More sharing options...
Deputy Posted May 27, 2006 Author Report Share Posted May 27, 2006 Thanks for that suggestion Norm. I haven't taken it apart yet, but I will give a close inspection to that screw. Yep...went to Damon's website. VERY cool!!! http://www.machinegunbooks.com/forums/invboard1_1_2/upload/html/emoticons/smile.gif You guys are the greatest for help.

Whiskey Brother Posted June 2, 2006 Report Share Posted June 2, 2006 Whoops... Didn't see this post. I'm glad you got it fixed okay. The grip bolt protruding too far does sound like a likely culprit on that one. You can also grind it down a bit instead of shimming it with a bunch of washers.

Gun cocks and fires and safety goes on normally. So what we have is Kahr either installing grip screws that are too long or taking too much off the recess in the wood where the screw goes. I'm off to the hardware store for some washers. Thanks a ton to EVERYONE for all their suggestions.

Norm Posted June 7, 2006 Report Share Posted June 7, 2006 Deputy, I'm glad the info helped. I call this predicament the "getting screwed- LITERALY!" Kahr----> http://www.machinegunbooks.com/forums/invboard1_1_2/upload/html/emoticons/nutkick.gif I hope that the rest of the gun is in good working order. Norm PS- don't forget to inspect the parts for burs that may have resulted from it jamming. Link to comment Share on other sites More sharing options...

Norm Posted June 7, 2006 Report Share Posted June 7, 2006 Damon, Even rednecks get lucky now and then. http://www.machinegunbooks.com/forums/invboard1_1_2/upload/html/emoticons/blink.gif BTW, do you still sell the 28/21 stock slide assembly? The one you sold me years ago still looks and works great. Maybe Deputy's next Thompson project will be a detachable stock and 28 trigger frame. It sure makes a 27A1 look better AND it will fit in Kahr's FBI case. Norm Link to comment Share on other sites More sharing options...
Deputy Posted June 8, 2006 Author Report Share Posted June 8, 2006 Phil: Must be that much-improved quality control now that Kahr has taken over things http://www.machinegunbooks.com/forums/invboard1_1_2/upload/html/emoticons/laugh.gif I wonder how many more Kahr Thompsons are having this exact same problem? Once is a glitch. Twice....sounds like the assembly line is screwed up. http://www.machinegunbooks.com/forums/invboard1_1_2/upload/html/emoticons/dry.gif Dep Link to comment Share on other sites More sharing options...
Deputy Posted June 9, 2006 Author Report Share Posted June 9, 2006 Went to my hardware store to get the washer/spacer today. Dang wedding plans kept interfering with important stuff http://www.machinegunbooks.com/forums/invboard1_1_2/upload/html/emoticons/tongue.gif Of course, my first thought was to get a slightly shorter grip screw. But it seems Kahr is using some kind of weird thread for the grip screw. NOTHING matches, not coarse, fine, or metric thread. Anyway, I wanted a washer that would fit inside the hole at the base of the grip. Problem was ALL the washers, flat or lockwashers I looked at, were too big to fit in the hole. What I ended up doing was going in the plumbing section and getting a flexible plastic washer designed to fix leaky faucets. I had to lube it to slip it on the grip screw, and I had to trim it all around to get it to sink into the grip screw hole, but it's completely hidden and now the grip screw is tight and it doesn't interfere with the internal workings of the trigger/safety mechanism. On further reflection, I suspect an o-ring might also work. Oh well http://www.machinegunbooks.com/forums/invboard1_1_2/upload/html/emoticons/smile.gif Dep Link to comment Share on other sites More sharing options...
Deputy Posted June 10, 2006 Author Report Share Posted June 10, 2006 Phil: I have a grinder, but measuring how much to take off would have been iffy. I didn't really want to disassemble the internals of the trigger housing just yet. I may do what you suggest in the future if the current fix gives me problems, though. Now I must go work some VooDoo spells and pray to the ancient gods. I am going to try and order an M1 Kahr/Thompson and I need to get my good Karma in position. I need to implore the ancient ones to make sure (1) it's available to order from my local gun shop and (2) it was assembled on any night but a bowling night and the assembly line monkey was given his supply of bananas for the day http://www.machinegunbooks.com/forums/invboard1_1_2/upload/html/emoticons/laugh.gif I'm still planning on a future purchase of a FA Thompson, but for now I have to be content with the Rube Goldberg look-a-likes http://www.machinegunbooks.com/forums/invboard1_1_2/upload/html/emoticons/biggrin.gif Dep Link to comment Share on other sites More sharing options...
Norm Posted June 10, 2006 Report Share Posted June 10, 2006 Deputy, Let's hope you don't get a "Friday" gun. You will like the M1 because it is easier to aim. You don't have to look through the cocking knob to aim it and the rear sight is easier to use. BTW, if you want a full auto Thompson- remeber, they won't get any cheaper AND the supply of "shooters" seems to be get smaller every year. http://www.machinegunbooks.com/forums/invboard1_1_2/upload/html/emoticons/sad.gif Shoot safely- Norm Link to comment Share on other sites More sharing options...
First Sergeant Posted June 11, 2006 Report Share Posted June 11, 2006 Deputy, Given a choice I'd put off the wedding and get a FA Thompson. Not that the wife will get any cheaper either but shooting a FA Thompson is the most fun you can have with your pants on. Good luck on both ! Stay safe Chuck (another Dep.)

Deputy Posted June 11, 2006 Author Report Share Posted June 11, 2006 Well I got lucky today. Got my order in for an M1 Thompson AND they had THREE of them in stock. My gun store guy nearly feinted when he found that out!!!!! I also ordered a S&W Model 1911... http://www.smith-wesson.com/webapp/wcs/sto...709&isFirearm=Y This is my third S&W auto and my second 1911 model. Can't believe how nice they are made compared to Colt. Poor Colt. They went under so many times I think the people they have making guns forgot how to do it right. So next week I get my wedding presents early http://www.machinegunbooks.com/forums/invboard1_1_2/upload/html/emoticons/biggrin.gif Dep Link to comment Share on other sites More sharing options...
