Had friend take a brand new Colt Series 80 Commander to a nationally known (think American pistolsmith Guild) pistolsmith for a triggerjob. Got the gun back, and very shortly had an AD...firing pin block was removed and the hammer hooks taken down past the safe limit. My friend dropped the slide, and hammer bounce took care of the rest.

Didn't set well when a gunsmith friend refered to this nationaly known pistolsmith's shop helper/apprentice as "Monkey Boy"!
Stuff happens, give him the opportunity to make it right.
