[Changed the title 3/26] Anyone ever done this? I'm looking at getting a P250/P320 full-sized barrel for either .357 SIG or .40 and threading them to shoot in a compact model. Has anyone ever done this? I wonder if you could do the same with a P226 barrel for use in a P229? Or a P220 barrel in a P220 Compact or P245.This message has been edited.

I have no idea on your exact question. But I would sumise that if the barrel runs before threading it will be fine after. I have done this with glock barrels no issue fwiw. “So in war, the way is to avoid what is strong, and strike at what is weak.” | |||

Or does anyone know a company that custom threads pistol barrels?This message has been edited. Last edited by: AUTiger89, Phone's ringing, Dude. | |||

The Berretta 92 barrel is typically longer and can be threaded- I believe this is what the OP is attempting to do. Tornado Technology is a reputable company that does barrel threading. https://tornadotechnologies.co...ading-shop-services/ | |||

I can’t answer all of your questions definitively, but a few thoughts. Thunder Beast rethreaded a barrel for me a few years ago. It was a T/C barrel made by a small manufacturer and the threading was misaligned with the bore. TBAC cut the original threads off and threaded it properly. I have no idea whether they would thread a pistol barrel, but it might be worth contacting them. https://thunderbeastarms.com/ Have you acquired the 357 or 40 P320 barrel(s) you were thinking of? The thickness of a 40 S&W P320 barrel between the bore and outside looks to me to be pretty thin for cutting threads into. A 357 barrel would add an extra 0.5 mm of thickness to work with, but …? Perhaps it’s possible, and maybe a company like TBAC would already know the answer. I can’t confirm it positively now, but I am 90% certain that the locking inserts of P226 and P229 pistols are different and a P226 barrel cannot be used in a stock P229. There was discussion of all that here years ago, but it’s been so long that I no longer recall the details. I would recommend confirming before buying the parts for such a project. Added: I decided to try to find my old list of SIG parts. Although they have changed part numbers at times, based on what I have, there were definitely different locking inserts for the P226 and P229. There may have even different parts for 9mm and 357/40 P229s, but I can’t be sure from the parts numbers. Because the locking inserts were different, the barrels were different as well, and a P226 barrel will not work in a stock P229.This message has been edited.

Thanks! Their web site only lists SIG barrels in .22LR or 9mm. I'm looking to: - Have a P250/P320 Large .40 barrel threaded to fit in a P250 Compact - Have a P250/P320 Large .357 SIG barrel threaded to fit in a P250 Compact - Have a P250/P320 Large .45 barrel threaded to fit in a P250 Compact - Have a P220 (standard) barrel threaded to fit in a P227 SAS or a P220 Compact All of these would be around a half inch difference in length (such as between the P250/P320 Large and Compact models), so I did check the barrel lengths. I'm not really that interested in the P226/P229 thing, but I was curious if it was possible - and in my case it would be in .40/.357 SIG. I have another local company I'm going to check with, and I'm going to check with SIG. I was just curious if anybody here had any resources or experiences doing so.

I'll try and look at some 9mm barrels, threaded and non-threaded, to see if there are differences in barrel thickness. I'm not switching between 9mm and .40/.357 SIG, so the locking block shouldn't be an issue. 9mm threaded barrels are pretty easy to find, but .40 and .357 SIG aren't as easy, as well as P250/P320 .45 barrels and P220 Compact threaded barrels.

Well, I found someone local to thread pistol barrels, but he wants $300 per barrel... Phone's ringing, Dude. | |||

I would only have a pistol barrel threaded if I could not buy a threaded barrel for that pistol. I have seen some aftermarket threaded barrels strike baffles and destroy cans. These were threaded by reputable machinists. I’m no machinist, but pistol barrels are so short it may be difficult to get runout precise enough prior to threading. | |||

Hence: https://sigforum.com/eve/forum...858/m/8240000005/p/1 As I have discussed elsewhere, checking alignment is a good idea, I believe, because it doesn’t have to be Bubba in the garage who’s doing the threading for it to not be done correctly. ► 6.0/94.0 “I can’t give you brains, but I can give you a diploma.” — The Wizard of Oz | |||

Absolutely! I've got some alignment rods that I'll check before giving him more business. Still can't decide if $300 per barrel, plus the cost of the barrel, is worth it. Dean - yes, I'm only wanting to have barrels threaded that I can't find on the market.
