It only makes sense that one of the leading duty and self-defense pistols should have a rimfire counterpart. Carry an M&P9 to keep from getting robbed; practice with an M&P22 to keep from going broke. The M&P22 has a 12-round magazine, a 4.1-inch barrel and weighs 24 ounces. MSRP is only $419 and it drew quite a few questions yesterday at the Smith & Wesson booth.
