Opinions on 645
Our SWAT guys had 645 years ago and some of our people still carry 645's or 4506's. Con opinions: Heavy, too large for anything buy most dedicated holster wearer, some sharp edges. Old style ambi safety has a habit of losing one side with regularity. Pro: Reliable with 2nd Generation magazines only (I saw a lot of the 1st gen. mags shuck the top round skyward when the guys whipped them out to reload, others split at seams or feed lips). Would always feed PD reloads that choked a Glock. To me, trigger is too crunchy and heavy, but Smith triggers smooth with use. I think the 4506, especially the TSW, is MUCH better. Never formally tested the guns for groups.
