My 1st posting on this forum,and I have a question.I am NOT the most knowledge person about S&W auto,I currently own a Model 39-2 in Nickel,really like weapon,but I have always wanted a 45acp,I have found a 645 in really nice shape,but its not local so seeing it in person would be hard. Its being sold for $500.00 with 2 mag's,Right side holster(I'm left handed) and its been modified to take a 4506 wrap around grip. Is this a good price and are they a good running pistol in general? My 39 eats just about anything I feed it and I hope the .45acp are the same.Thanks for taking the time to respond and for the help.Clint
