I have a bid in on this barrel from Storm lake. I'm assuming it should drop into my XD-40 Mod 2.0, correct? If so, I know I will need 9mm mags. Will the 40 cal recoil spring assembly work with the 9mm?
I added a Storm Lake 9mm conversion barrel to my Smith M&P 40 cal. and it's been running flawlessly for over 2000 rounds now, factory and hand loads .My 9mm barrel is for cheaper range practice. I usually carry the M&P with my Storm Lake 357 Sig barrel installed..40 to 9mm conversion. The only perfect conversion is changing the whole slide. How do you expect a piece of brass in 9mm to be extracted reliably each and every time when the extractor is barely catching the edge of the brass rim because it is designed for a larger diameter .40 cal. brass? Yes it works most of the time but don't ever use a 9mm conversion barrel for carry!!!!!!!!!!!!!!!!!!!
I believe I specified the 9mm conversion barrels are for RANGE USE, NOT for SD situations. When I'm out walking early in the morning I carry my SCCY CPX-2 loaded with Hornady Personal Defense ammo, in a back pocket. I would prefer my Rock Island 1911 in 38 Super but that's a bit hard to carry wearing shorts and a T-shirt, lol.Again the time you need to use 9mm for self defense in your weapon will fail to extract. It's Murphy's Law. Mr. GaCop103, you have been lucky. Look at the physics of the two bullet diameters. A diameter that is 75-80% the size of the designed bullet is bound to fail to extract at some point in time. I have sold conversion barrels for 30 years beginning with .400 corbon, 9mm and .41 Action Express. I have always given my customers the plus and minus qualities. Some clients rave about the greatness of the conversion but others moan over the failures to extract. This does not include .357 SIG (Same size brass as .40 cal.) DO NOT TRUST 9MM CONVERSION BARRELS FOR SELF DEFENSE! PLEASE, PLEASE TRUST ME ON THIS!
