This is a COMPACT Smith & Wesson M&P 9mm 10-round magazine (with optional finger rest). These 10-round magazines feature the same high-quality steel construction and matte black finish as the mags that came with your gun, along with an optional finger rest that increases the grip area on your M&P Compact 9mm pistol. Arguably the best American made striker-fired pistols on the market today, Smith & Wesson's M&P pistols are shooter friendly and tough enough to meet the needs of military & police units-thanks in no small part to their reliable factory magazines. The extra grip area provided by the optional finger rest makes for a more comfortable experience, ideal for target shooting, tactical drills, or any use where concealment isn't a top priority.
