Some other things/upgraded components I forgot to mention; the recoil spring assembly has been upgraded to a BUSA solid steel recoil spring guide rod and a Wilson Combat 14# chrome silicon recoil spring; the firing pin spring has been replaced with a Wilson Combat chrome silicon firing pin spring; and I also am running the extractor with a Wilson Combat standard strength chrome silicon spring.
The locking block assembly has been upgraded to the current generation of Beretta 92 locking block assembly.
I've already discussed all this before, but thought I'd recapitulate for the benefit of those new to the thread.
Best, Jon
