Pick up the Umarex Smith & Wesson M&P 40 for some good old fashioned affordable BB plinking fun. This officially licensed replica uses the standard replacement magazine sold in a two-pack so stocking up on extra mags is also affordable. This 19-shot BB pistol is powered by cheap, reliable 12 gram non-threaded CO2 and shoots BBs at 410 FPS.
