Colt Officer's Model - 45 ACP
Charter Arms Off Duty - 38 Special
Ruger 22 Cal with Bull barrel
Every one of those have been shot extensively. I know for a fact that I have over 10,000 rounds through that Colt and at least 3000 horsed-up (and I do mean horsed up) rounds through my 41. Maybe a thousand throught the 38 Special and I am not even going to try to guess how many I've ran through the 22.
