Are you a worrier?
Get a new block (about $65 from Beretta USA) and forget about it for about 20K rounds w +P ammo, or twice as much (or more) w std pressure ammo.
Most LE trade ins have lots of holster wear, little actual use; very few PDs/LEOs shoot more than a few hundred rounds a year.
Blocks rarely just go and lock up the gun; usually they start to jam a lot first. Replace it then.
Saw an ad for Beretta kits (barrel, block, guide rod/spring, etc) for only $95 at RPB, 404-297-0907. Get one of those and relax.
