Instead of having the 646 tuned up for Steel Challenge, I could find some SW collector, sell it and then use the money to buy 2 S&W 625s, which are definitively the bee’s knees. That way all my gun kata stays the same since the 625s eat out of moonclips, and I only need to buy one kind of ammo to feed them. Decisions, decisions. The 625s also have the advantage of being an N-frame, which is full of win and awesome.
The 646 isn’t a bad gun, mind you. It just hast really lit me on fire with enthusiasm, unlike the 625 which was love at first trigger pull. Plus, I have one 625 already, and could always use a backup in case the first one goes TU at an inopportune moment during a match.
