I have seen folks mention factory options for converting small calibers (model 33 .357 barrel swapped out for the stock model 27 .40 barrel)...

Just wondering what sort of conversions do folks know about for the big guns (10mm and .45)?

For example, can the barrel of a model 20 (10mm) be safely placed within a slide for a model 21 (.45)...?

I have seen aftermarket options for the full size frame of either a 10mm or .45 to mate up to a slide made for a 50cal pistol round...but that is about it...

Thanks!

I have done my research and I haven't found much. Figured it would be a good idea to list the possible caliber conversions barrel swaps that are available, sort of like a reference guide for us Glock guys. If you have another that isn't listed or I have something wrong here please let me know. Don't tell me what you "think" though, please make sure it is accurate information. These are just the few that I know of. Wish there was a .22TCM barrel :p

9mm- .22LR, or upper swap with trigger housing/ejector and magazines to .40S&W, .357SIG, .45GAP (can only upper swap to larger caliber if 9mm frame has 3 pins)

40 S&W- 357 SIG, 9mm, .22LR

357 SIG- 40 S&W, 9mm, .22LR

45 GAP- I have no idea...

45 ACP- 50 GI, 460 Rowland, .400 Corbon, 10mm, .45 Super, .40 Super, .22LR

10mm- 50 GI, .40 S&W, 9x25 Dillon, 357 SIG, .22LR
