The Mountain Gun series is probably the best series of guns Smith ever made and the .45 ACP the best caliber of the series so you now own the Best of the Best....
Besides .45 ACP and +P if you talk to the guys at Buffalo Bore you'll find a lot of shooters use their .45 Super ammo in currently made Smith 625s.
I've had three over the years but because I am mainly a .41 Shooter have sold them off... The last one went last years with box and paperwork for about $1200 after I picked up a 625-7 Performance Center 5"...
$800 is a GREAT deal....this one just sold for a lot more...
