G20 conversion

[critrxdoc]

I have .40 and .357 sig conversion barrels. These have shot fine with stock mags and recoil spring until the last range trip. The sig stove piped and the I switched to the .40 barrel and it failed to go completely into battery and I had to assist each round into chamber. Any ideas would be helpful. Thanks

check recoil spring/guide. slide lube? clean mags?

What ammo were you running through it? What # is the recoil spring, and how many rds through it with the same spring?
