JayDee Posted June 16, 2014 Share Posted June 16, 2014 (edited) Recently, in a local match, I won a certificate for a match barrel. Currently I have two government sized 1911s: .40 and 9mm. I could always just get an extra barrel for one of these 1911s, but wanted to see what other people are doing with alternate calibers. It looks like I could get a 10mm barrel for the 40 or a 38 super for the 9mm. I don't yet have a "need" for either caliber, but it does sound interesting to be able to swap calibers. Do any of you have a setup like this? If so, what do you use the 38 super and/or 10mm for? Thanks Edited June 16, 2014 by JayDee Link to comment Share on other sites More sharing options...
Steve RA Posted June 16, 2014 Share Posted June 16, 2014 Or you could probably sell the certificate on here. Link to comment Share on other sites More sharing options...

Thanks The problem with trying to do a caliber conversion on a 1911 by changing only the barrel: the extactor is a critical fit so it probably would not extract right. I ran into that problem on a springfield XD when I bought the .40 version and got the 9mm "conversion" barrel. The XD uses a "fixed" extractor similar to 1911. Extraction is iffy on the XD, I have to change the extractor with the barrel. In designs with a pivoting (spring loaded) extractor, the extra range of movement helps keep the case rim held tight to the edge of the breech face.

JayDee Posted June 16, 2014 Author Share Posted June 16, 2014 @bountyhunter - I understand that the extractor has to jive as well, but if I got a conversion barrel it would be a 10mm for the 40, or a 38 super for the 9mm. I believe that the extractor should work since the cases are nearly the same diameter. Link to comment Share on other sites More sharing options...
CHARLES D Posted June 16, 2014 Share Posted June 16, 2014 I went the opposite from you. I switched from a 38 super to a 9mm. Only problem I had was the 38 super mags. Didn't work well with 9mm ammo. Purchased Tripp mags and now the gun runs like a champ. Link to comment Share on other sites More sharing options...
Larry White Posted June 16, 2014 Share Posted June 16, 2014 (edited) .40 t0 10mm you would need the barrel and a recoil spring, and maybe mags, 10mm wont feed thur .40 mags then if you ever had the itch to kill a Chysler Imperial you would have a handgun to get it done. Ever thought about a .40 to .357 sig?-----------------Larry Edited June 17, 2014 by Larry White Link to comment Share on other sites More sharing options...
JayDee Posted June 17, 2014 Author Share Posted June 17, 2014 Aside from shooting Chryslers ....... Do any of you have a setup like this? If so, what do you use the 38 super and/or 10mm for? Thanks Link to comment Share on other sites More sharing options...
