RobertLx Posted May 28, 2015 Share Posted May 28, 2015 ...anyone ever done it? Any reason you can't put a 9 barrel in a 38 super gun? Limited pro Link to comment Share on other sites More sharing options...
kneelingatlas Posted May 28, 2015 Share Posted May 28, 2015 (edited) I've done it, no problem. The 38 super breech face is slightly larger than 9mm, so if you go the other way it will only chamber 38 super comp.

Is this correct or do you have it backwards? I'm not very familiar with .38 super, but I thought the semi-rimmed case would mean that the 9mm breach face is slightly smaller?

gunnit Posted May 28, 2015 Share Posted May 28, 2015 The 9mm breech face is slightly smaller than the 38 super, but not by much. You can run the 9mm barrel in the 38 super slide, you might have to change to the 9mm extractor in that 38 slide, and then you may or may not have to tune the extractor depending on how it runs .

aceinyerface Posted May 29, 2015 Share Posted May 29, 2015 It wouldn't be legal for Production, though. D4 21.3 Link to comment Share on other sites More sharing options...
earthshine402 Posted May 29, 2015 Share Posted May 29, 2015 (edited) It wouldn't be legal for Production, though. D4 21.3 you sure about that? Technically, "caliber" is the diameter of the bullet - 9mm and 38 super have the same diameter bullet. On the RO overlays, there is a diameter for 9mm, 40, and 45. There are not separate holes for 9mm and 38 super. edit: I just emailed DNROI about this, will post answer.

earthshine402 Posted May 29, 2015 Share Posted May 29, 2015 I will also add that I think this is a terrible idea: to buy a 38 super and get a 9mm barrel for it, just wait for the 9 to be available! Link to comment Share on other sites More sharing options...
Prov1x Posted May 29, 2015 Share Posted May 29, 2015 This has already been ruled on by Amidon when he was the NROI. He said it was legal due to the bullet diameter as stated above. I'm not going to search for it but it is on this forum. Link to comment Share on other sites More sharing options...
BeerBaron Posted May 29, 2015 Share Posted May 29, 2015 It's no problem. I ran my stock 2 that way. Was a large frame 38 super with spare 9mm barrel. Worked fine. No need to change ejector or extractor or even the mags. Link to comment Share on other sites More sharing options...

I'm not going to search for it but it is on this forum. I recall that also. 38 and 9 are interchangeable, so is 10 and40 ... using appropriate barrels.

shabodah Posted May 30, 2015 Share Posted May 30, 2015 (edited) I am having no problems running my limited pro 9mm barrel in my 38 super stock 3. I haven't run my 38 super barrel in my 9mm stock 3 yet, but I see no reason it wouldn't run 38 super comp, 9mm super comp, and 9x23 Winchester, if using appropriate springs. Don't get me wrong, a dedicated barrel for 9mm super comp and 9x23 would be better for them, though. Edited May 30, 2015 by shabodah Link to comment Share on other sites More sharing options...
aceinyerface Posted May 30, 2015 Share Posted May 30, 2015 i assumed someone put a 10mm barrel in a .40 and blew it up in a match. If it isn't to prevent this kind of thing, what is the rule there to prevent? Link to comment Share on other sites More sharing options...

kneelingatlas Posted May 31, 2015 Share Posted May 31, 2015 But you can parts swap to your hearts content between approved guns. This is not what Amidon ruled, he explicitly stated caliber conversions were not legal and also ruled 38/9 as well as 40/10 the same calibers.

aceinyerface Posted May 31, 2015 Share Posted May 31, 2015 I'm just trying to follow along... The goal is to keep the guns in the division (more or less) as produced from the factory So barrel swapping a 38 super to a 9mm is ok but to a 40 is not ok. I don't get the logic there because neither is as produced from the factory. I'm wondering if the rules regarding this have become ineffective. Or just silly. You can trick a Tanfo with Xtreme custom parts, even the trigger and hammer, because they are "factory parts" but in the US you cannot purchase any new firearm that comes with those parts. Over seas, you can special order a firearm with those custom parts, if I understand it correctly. Somehow that meets the standard of "2000 manufactured and available to the general public". You can shoot an Accu Shadow if it was born an Accu Shadow, but if the CZ Custom shop puts the Accu Shadow bushing on a Shadow, it isn't legal? Do I have that right? And I can part swap the safety off my Stock 1 to the Stock 2 so I can get a higher grip and not engage the ambi safety by accident, not a factory configuration but legal because both guns are on the approved list. But, if I just take off the right side of the Stock 2 safety, it would be an external modification. How does any of that conform to the idea that this Production division is for factory produced guns? Link to comment Share on other sites More sharing options...
kneelingatlas Posted May 31, 2015 Share Posted May 31, 2015 You can check that rationality at the door bud I'm just sharing what I know, do I agree with all the Production division rules? No, that's part of the reason I don't shoot it. Link to comment Share on other sites More sharing options...

Then whoever feels the need can contact Troy with Amidon's answer and see what the ruling should be or will be. An "official" ruling would be nice for everyone. I have all 9mm Stock 2 and 3 so this does not directly affect me. Edited June 2, 2015 by Prov1x Link to comment Share on other sites More sharing options...
aceinyerface Posted June 2, 2015 Share Posted June 2, 2015 I think it is a loop hole in the phrasing that needs to be closed. You can't put a .38 super in a 9x19 and pull the trigger so it is a different "caliber" even if the diameter is the same. But my opinion doesn't count. However, you can get 9mm 9x19 projectiles in .355, .356, and .357. This all needs to be tightened up. Link to comment Share on other sites More sharing options...
Prov1x Posted June 2, 2015 Share Posted June 2, 2015 Copied Email response from John Amidon DNROI Jun 6 2014 After discussion with the USPSA President on this issue, it was determined that there is no difference, really. Caliber could be interpreted as the width of the bullet, more so than the actual round. This would allow the Tanfoglio Stock III to have a slide that states 38 and a barrel of 9mm. As the rules state caliber/cartridge .38 cal./9X19 .0354. John Link to comment Share on other sites More sharing options...
aceinyerface Posted June 2, 2015 Share Posted June 2, 2015 Since it is an internal modification, can I hog out a 9mm barrel to fit a .356 Winchester rifle cartridge? Link to comment Share on other sites More sharing options...
