The G20 will feed CCI .40 S&W snake shot pretty well, too.
Hmmm, I haven't thought about that. I'll have to give them a try in my Glock 20 or 29.
My G20 and G29 all did (two 20s, one 29). YMMV, but I hope not. They likely won't CYCLE because the impulse from those loads is too low, but they'll feed if you rack the slide. Never found a semi-auto that will cycle CCI snake shot reliably, regardless of chambering/cartridge.
