All production guns with frame mounted firing pins have M.I.M. hammers.

MOST all Performance Center revolvers have forged hammers and triggers,
BUT, check, because some very late guns have mim parts.

No 625-4s I guess because a deal on one has just eluded me.
New in box they can bring crazy money .
And I don't have any holes in the collection that I am hot to fill at this time.

The last Jerry Miculek design 625-7 sold on Gone broker for $1400.00
I missed that one. so had to track this one down out of state.


Good Luck,
