45cal Posted September 30, 2015 Report Share Posted September 30, 2015 I'm about to SBR my Thompsons. I have a WH 1927A1, and Kahr M1. Both are closed bolt guns. I'm really considering getting a Kahr 10.5 for the M1. Are there better options? Will the Kahr Arms 1927A1 barrels fit and function in a WH gun?

45cal Posted September 30, 2015 Author Report Share Posted September 30, 2015 Also where's a good place for the engraving? Link to comment Share on other sites More sharing options...
Bender Posted September 30, 2015 Report Share Posted September 30, 2015 I'm planning to use a kahr 10.5" barrel in my WH AO 27a1. Also, I think most of the guys who can swap the barrels can also do the engravings. Just sent my form 1 out a couple weeks ago. Link to comment Share on other sites More sharing options...
anticus Posted September 30, 2015 Report Share Posted September 30, 2015 A GI barrel will screw in to a WH or early Kahr receiver. The threads are identical. As I understand it, the later Kahrs have a press fit for their barrels and comps. Link to comment Share on other sites More sharing options...
mike in pa Posted October 1, 2015 Report Share Posted October 1, 2015 I bought a Kahr M1 back on 2009 for a SBR project and the barrel was threaded in. I did not know that they went to pressed in barrels. Link to comment Share on other sites More sharing options...
45cal Posted October 1, 2015 Author Report Share Posted October 1, 2015 Are the GI barrels that much better than current production? I need some idea's as where to engrave on the receiver Link to comment Share on other sites More sharing options...
Bender Posted October 1, 2015 Report Share Posted October 1, 2015 In front of the magwell on the bottom of the receiver is one option, or the barrel-especially if your doing a smooth barrel, then you can hide the engraving under the horizontal handguard. These are two options I've heard. Also of course the receiver. Near the patent info or the otherside. This of course only looks decent if the fonts match perfectly IMO. Everyone seems to suggest GI, but I'm still planning on trying a new production kahr 10.5" barrel. Link to comment Share on other sites More sharing options...

Everyone seems to suggest GI, but I'm still planning on trying a new production kahr 10.5" barrel. For what it's worth... The reason people suggest GI or even Green Mt. barrels is the difference in steel quality and build quality. The Kahr barrels are made nowhere close to the original specs. To many fins, fins and barrels are not the correct dia., and the chambers are setup and reamed like a 1911 not a machine gun. I think that is where some of the feeding problems stem from in the Kahr and maybe even the W.H. guns. The steel is of lower quality on the Kahr barrels and the rifling on mine from the factory was rough as hell when compared to my now Green Mt. barrel. Just to show the difference in profile, the two pictures below show a Green Mt barrel (which is made to GI specs) in both an original WWII fore-grip and a Kahr fore-grip that was profiled to my original Kahr barrel. You really can see the giant gap in the Kahr grip due to the larger profile of the Kahr barrels... Jon Edited October 4, 2015 by 06AngusSG Link to comment Share on other sites More sharing options...
Bender Posted October 7, 2015 Report Share Posted October 7, 2015 Thanks for that info Jon.I didn't know about the differences, but the trouble is finding GI barrels. Can't seem to find them myself. Link to comment Share on other sites More sharing options...

06AngusSG Posted October 8, 2015 Report Share Posted October 8, 2015 (edited) ^i thought they have new manufactured barrels that they make in house?That is correct. I have never seen any reviews regarding quality, here or otherwise. On the other hand... I can personally attest to the Green Mt. quality as can other members here. If you can't end up finding a GI this would be a good and inexpensive alternative. http://www.gmriflebarrel.com/1928-thompson-sub-machine-gun-barrel/ Jon Edited October 8, 2015 by 06AngusSG Link to comment Share on other sites More sharing options...

kinger Posted October 10, 2015 Report Share Posted October 10, 2015 Hello... on the topic of the Thompson SBR, is there someone that you could recommend for doing the barrel swap? I have a completed form 1 and the guy I had lined up is no longer doing the work. Link to comment Share on other sites More sharing options...
Merry Ploughboy Posted October 10, 2015 Report Share Posted October 10, 2015 Hello... on the topic of the Thompson SBR, is there someone that you could recommend for doing the barrel swap? I have a completed form 1 and the guy I had lined up is no longer doing the work. I believe that a couple board members - Reconbob (noted above as a WWII vintage barrel source) and Deerslayer - both used to do barrel swaps. I'd check with them. Best of luck.

kinger Posted October 10, 2015 Report Share Posted October 10, 2015 (edited) Thanks for the information. I sent Phili Ordnance an email through their website so hopefully they will respond. Correct me if I'm wrong, but is Deerslayer Dan Block? He was referred to me by a friend. I have poked around on the Internet for an email for him and came up empty. I will try and reach out to him on this site. Edited October 10, 2015 by kinger Link to comment Share on other sites More sharing options...
kinger Posted October 10, 2015 Report Share Posted October 10, 2015 I found Deerslayers email address and have emailed him as well. Thanks again for the help! Link to comment Share on other sites More sharing options...
Gio Posted October 11, 2015 Report Share Posted October 11, 2015 kinger, Whoever you get I would change out the front grip mount. Change it to a military style one piece that is also 1/2" . You probable have a 3/4" and two piece on it know. You would have to buy a front grip. Buy a military or have Dan make you one. That would take care of your barrel for good. Then you only have to put military lower to have a good looking semi. Good luckFrank Link to comment Share on other sites More sharing options...
06AngusSG Posted October 11, 2015 Report Share Posted October 11, 2015 (edited) Yes, deerslayer is Dan Block. Great guy to deal with. I got my EZ-pulls from him. If you decide to go Franks suggestion and get a WWII or Dan Block grip... reconbob (Phila Ordnance) also makes repro 1/2" grip mounts.I have one on my gun and it is made to outstanding quality.

Bender Posted October 11, 2015 Report Share Posted October 11, 2015 Frank,Just curious, what is the difference with the front grips, I don't see much of a difference between the wood depending on 1/2" or 3/4" gripmounts. I'd really like to know what to look for. Link to comment Share on other sites More sharing options...
Gio Posted October 11, 2015 Report Share Posted October 11, 2015 Bender If you put a 1/2' grip mount and you have a 3/4" the groove in the wood will be to wide for the 1/2" mount. Most of the semi's have 3/4 grip mounts. I have a early WH pistol that has a 1/2" grip mount but its the 2 piece. If I changed out the barrel I would put a one piece grip mount on it. The 2 piece mounts get loose or brake off. Frank Link to comment Share on other sites More sharing options...

I am just waiting for Phili Ordnance to respond to my barrel inquiry so I can complete the purchase. Then it is off to Dan for the barrel swap.

kinger Posted November 13, 2015 Report Share Posted November 13, 2015 I want to shout out a big THANK YOU to Dan for the barrel work he did on my Thompson. I can't say enough good things about his work or his pricing. Thanks again Dan! http://i68.tinypic.com/209ltac.jpg Link to comment Share on other sites More sharing options...
