Hi Six
There may be a "Depends" in here somewhere (no, not the package depends). The original AWA guns were made by Armi San Marco. For all practical, they are a dead ringer for a Second Gen Colt. The later AWA Ultimate are not ASM sourced but were still built PRETTY Much as a Colt Replicant. SO:
The firing pins are retained in the same manner, with a cross pin through the hammer and through a small notch in the firing pin. You should be able to source Pietta Firing Pins, Original type Uberti Firing Pins, or even Colt Firing Pins. There can be a SMALL amount of firing pin movement on the cross pin which is normal. It is also possible the cross pin is beginning to wear.
Since you cite the Firing Pins are mushrooming, I am certain the guns are ASM guns and Pietta Firing Pins should fit. Check availability with VTI Gunparts. Be certain to also order new cross pins.
