Glock bbl conversion, ? spring damage

glockmatt

I bought a bbl conversion for my G23. An EFK Firedragon, stainless NM .357 Sig from .40 S&W. Functioned well with FMJ, jammed with Gold Dots. Good lock up and very accurate. My original G23 had approx. 2500 rounds thru it without any spring replacement. After 250 rds. of .357 my slide stop spring failed and my slide slid off the frame. I subsequently replaced all springs. No new problems. Is it true that the G23 and G32 frames are the same? How much extra wear and tear does the increased pressure of a .357 Sig do to a Glock frame? Is the spring failure a fluke or maybe related to the increased pressure?

40 S&W is a high pressure round. Your recoil spring was probably quite weak after 2500 rds. The 357 Sig is worse, and if you shoot it a lot you are going to have to change springs quite often. Lay in a stock of them.

I bought a 357 SIG Firedragon barrel several years ago at a gunshow for my Glock 22 and they sold me a stronger recoil spring to go with it. It has worked fine. You might want to get a ISMI 22# spring for it. I like ISMI springs and they are about the same price as the factory Glock springs. I think they last longer.

If possible I would like to stick with OEM for springs. Are the recoil springs the same for the G23 and G32? They are quite inexpensive. If they are of different strengths,I can change springs when changing bbls
