Which firearm have you fired most and the least fired one.For me my BT-99 with about 15,000 rds through it,and for the least would be my Safe Queen,Kimber 25th Anniversary Gold Match 45 ACP,Serial No.6 out of only 500 made.
Least fired: My John Wayne commemorative rifles and single action Colt's. They have never been fired.
Most fired: At one time it would have been my Beretta 686 Skeet shotgun, but since my leg injury I can't shoot skeet anymore. So now it is my Low Wall in 45 Colt. But probably my 9422 gets the most action. Tom.
