Turpin81 Posted January 2, 2013 Report Share Posted January 2, 2013 (edited) Hello, I purchased a Auto Ordnance 1927 semi auto. I wanted the steel receiver however, that was not available in the pistol format. My question is, should I be concerned with an alloy receiver Tommy? I would like to know if anyone has experience with the newer A. Ordnance alloy 1927's. I heard allot of bad stuff with the older West Hurley models. I have read Savage built a few aluminum full auto Thompson's for the British to test out in WW2. The Brits said they wore to excessive in the mag slots, and the receiver's were to weak for combat use. However, I am sure aluminum alloy has came along way since the 40's though?

mnshooter Posted January 2, 2013 Report Share Posted January 2, 2013 The pistol version is aluminium only, so no choice there. Otherwise, get the steel. EZ pull spring instructions specify the steel gun only, so that should tell you something. Link to comment Share on other sites More sharing options...
Turpin81 Posted January 2, 2013 Author Report Share Posted January 2, 2013 Thanks, Yes from what I have read Aluminum is strong but is soft so it will wear quicker if steel parts slide or slam into it frequently. I suppose that's why A.O. has such a strong recoil spring in there 1927a1 Link to comment Share on other sites More sharing options...

I suppose that's why A.O. has such a strong recoil spring in there 1927a1 I built a semi-auto Thompson that has an aluminum trigger frame (lower receiver) and it definitely is showing signs ofwear although not as much as you you think. Modern aluminum can be made pretty durable. Remember, they use itin aircraft and those plane surfaces undergo huge forces.

emmagee1917 Posted January 3, 2013 Report Share Posted January 3, 2013 True , but when they slam a few times into the iron in a mountain face , they tend not to fare very well.Chris Link to comment Share on other sites More sharing options...
Turpin81 Posted January 3, 2013 Author Report Share Posted January 3, 2013 (edited) Hi, Thanks for the reply's. How old is that gun T-Hound. I am just curious to see how many rounds it held up to. I do wish I could get a replacement steel receiver to keep around incase this one wears out, However, I can't find Just the receivers for sale.

T Hound Posted January 14, 2013 Report Share Posted January 14, 2013 (edited) I have put 500 rounds (probably more because I don't really count) through it so far. It is a semi-auto of course which will always fare better than the TSMG aluminum receiversthey experimented with in WW2. But I have three Thompsons with different configurations. So I shoot all three. If you really want a steel receiver for a Thompson pistol you could always buy one ofRecon Bob's (Philadelphia Ordnance) 80% receiver and MAKE one yourself. Itcan be done with a 5 speed drill press and LOTS of patience in drilling and grinding itout. Then you must have a lower trigger frame which does not have a hole or slotfor either a bolt on stock nor a slide on stock. Have the words "Thompson Pistol"etched onto the side and "voila" you have a Thompson pistol. I plan to build onemyself this year because it can legally have a 10 inch barrel on it because it isa pistol.

Turpin81 Posted January 16, 2013 Author Report Share Posted January 16, 2013 (edited) Thanks, T-hound. I was wondering if the 1921 and 1928a1 receiver's he sales are the same fit is my auto ordnance 27 ta5 pistol reciever?

T Hound Posted January 17, 2013 Report Share Posted January 17, 2013 (edited) If you mean "will the trigger frame of your pistol work with a Philadelphia Ordnance 1921 or 1928 receiver then the answer is no. These receivers are based off the Full-auto receivers and are therefore 1/10th of an inch higher than the semi-auto receivers. While the bolt channels are the same length and width they are NOT the samedepth. The semi-auto bolt would not, therefore, function correctly in the full-auto receiver. To make a semi-auto from the P.O. receivers you will have to go over to Weapons Guild and find a build for a semi-auto. A full-auto bolt will have to be modified to be semi-auto so that it will fit the Philadelphia Ordnance receiver, but you have to put in "denial" pins or islands that keep a full-auto bolt from fitting into your receiver and you will have to mill, grind, cut the former FA bolt to fit those denial islands. There are a few BATF approved designs out there. This assumes you have some machine experience or at least the desire to learn. Otherwise it becomes a felony. Not good. But the end result will be an authentic looking Thompson because the receiver will be the same dimensions as the TSMG. The bad news is that you can NEVER sell it to anyone, although I have heard you can sell to a Manufacturer or if YOU become a manufacturer.

T-Hound, Have to disagree with you on this . You can not as an unlicensed individual build a firearm for the purpose of selling. You are not required to put a serial number on the firearm but if you ever transfer it it must have a serial number and makers mark. You are not prevented from transferring the firearm at a later date. Note that we are talking about Federal law, not California. See the attachments.

T Hound Posted January 17, 2013 Report Share Posted January 17, 2013 (edited) I stand corrected. Thank you Joe! That actually is good news---for a change. Edited January 17, 2013 by T Hound Link to comment Share on other sites More sharing options...
Turpin81 Posted January 19, 2013 Author Report Share Posted January 19, 2013 Thanks guys. I dont intend to sell it though. Its good data to know just incase , thanks.I will keep you informed when and If I get a new reciever how it goes. I may just build a new semi auto , instead of putting the reciever on my current A.O. semi. pistol.Un-fortunatly at this time Philadelphia Ordnance does not make a reciever that will work with the A.O. bolt. like T-hound said its 1 10th shorter.Mabee I can have one milled down I/10th?lol all this work for a steel reciever thompson pistol.

Darn you A.O.!!! Understandable reaction Turpin81 but probably Kahr did it because the steelreceivers would be too heavy for a single hand hold for most people. I believethe rules require that the pistol can be held with one hand and by using the aluminumreceiver it is only 7 pounds, as a rifle, rather than 10.5 pounds. So after the stock is removedit becomes even less and "Voila" a pistol. And using steel, and more weight, probablywould have made a BATF approval more difficult in todays day and age of gun grabbing.But this is only my interpretation. Please don't take it as the Gospel truth. Edited January 21, 2013 by T Hound Link to comment Share on other sites More sharing options...
Turpin81 Posted January 21, 2013 Author Report Share Posted January 21, 2013 That makes since T-hound, I was just kidding though. . I was debating on ordering the P.O. receiver and finding a 28 bolt. or just getting my alloy receiver and frame metalife , nickel or some sort of quility finish to stop wear. I have found a guy who makes 80 percent steel receiver that has some to fit the A.O. bolt 1/10th shorter. however he's retail for over 600 bucks.

I suggest you go to Philadelphia Ordnance and check out ReconBob's website. He has multiple options and prices depending upon what you want. If you get thebasic 80% without writing or blueing then it is not expensive at all. Of course the extras, requiring a lot more work, are going to start inching the price up. I got mineunblued and without writing because that gives the option of either making a rifle OR a Thompson Pistol. I am pretty sure he told me once that he also does thesemi-auto 80% receiver so you could call and ask him. Link to comment Share on other sites More sharing options...
Turpin81 Posted January 22, 2013 Author Report Share Posted January 22, 2013 Would you have a link to ReconBob's website. I cant seem to find it on P.O. website. I email P.O. earlier and they said that they currently do not produce the part that I am looking for . I appreciate the help Link to comment Share on other sites More sharing options...
T Hound Posted January 22, 2013 Report Share Posted January 22, 2013 The URL is :www.philaord.com/ Are you sure it was Philadelphia Ordnance? He makes receivers in batches. Maybe he stopped makingthem due to lack of interest. Hard to say. But I PM'd him and asked so sooner or later he will confirm ordeny that. Link to comment Share on other sites More sharing options...
Turpin81 Posted January 22, 2013 Author Report Share Posted January 22, 2013 Good morning T-hound. I send an email to the contact us link on this site http://www.philaord.com/. they probably told me that because I also wanted to buy a frame to fit the receiver. I should have looked around the site and noticed they sell only receiver's. Link to comment Share on other sites More sharing options...
T Hound Posted January 22, 2013 Report Share Posted January 22, 2013 No brother, Bob also does sell the trigger frame (lower receiver), but it is only for the full-auto; i.e. you're righthe doesn't sell the SEMI-AUTO trigger frame that I have ever seen. I PM'd him a day ago to ask becauseI am curious since I buy receivers from him and plan to buy the trigger frame too. But a phone call duringthe day is probably your best bet. He's a nice guy, but just be warned that he will want you to getto the point because of his production time constraints. Link to comment Share on other sites More sharing options...
Turpin81 Posted January 23, 2013 Author Report Share Posted January 23, 2013 I will have to give him a call when I am not in class. Thanks so much T-hound. Link to comment Share on other sites More sharing options...
reconbob Posted January 23, 2013 Report Share Posted January 23, 2013 I made a couple of 4140 steel semi-auto M1 pattern receivers about a year or soago, expecting that there would be interest. I put one on gunbroker and it sold for(I think) about $440. At that price its not worth doing so I just dropped the idea. Bob/Phila Ord Link to comment Share on other sites More sharing options...

But was this version an 80%blued and have engraving? Or was it a bare metal 80% receiver? I know there is adifference on your full-auto 80% receivers.

T Hound Posted February 1, 2013 Report Share Posted February 1, 2013 Good morning. here is a link to the other semi auto receiver's I have found. http://www.thompsons...INFORMATION.htm Yes that is Doug Richardson's site. I actually have an order with him for a semi-auto receiver. The problem is thatDoug has not been able to see well enough to machine the back orders of his receivers for at least three years.Since he works alone, that situation is unlikely to change in the near future. Afterall, it has already been three years.But I wish Doug good health-especially eye health. Link to comment Share on other sites More sharing options...
Turpin81 Posted February 1, 2013 Author Report Share Posted February 1, 2013 Hi T-hound that is unfortunate, as a art major, I can only imagine how bad it would be to if I was unable to do the work I enjoy because of my eyesight. Link to comment Share on other sites More sharing options...
