Maybe someone on here can help out.
A FNP 40 was fitted with a new (threaded) barrel. All things are fine and dandy without ammo. However when using ammo, the gun did not go into battery.
I've looked at all outer dimensions and think that I've fitted those to proverbial death. While things go better, I still have no dice loading some ammo. To me it seems that the barrel throat is not cut wide enough, i.e. a "rounder" bullet - thus wider diameter at the throat - gets pushed and this causes the gun to choke. Conical bullets seem to be better in that area - i.e. smaller diameter and better "fit" into the throat.
I've looked at the gauges but don't want to buy them for that one-time use. Anybody has a .40 S&W Go and NO-GO gauge for checking the chamber? I'm in SLC and depending on distance can either swing by during an evening or on the weekend.
thanks for letting me know.
