RE: Which Handgun
Smith and Wesson 329PD, 44 magnum. Nothing else like it.
As far as the 40 caliber, I consider it the caliber of the month. It is not the first attempt at marketing the 10 mm. It is a fine caliber, but not in the league of the 44 Magnum for bear and such. If you wanted a 10 mm, or 40 S&W, try one of the revolvers. But that Titanium 329PD is the ultimate. Tom.
