Another real steel review by The Firearm Blog to help brushen up our dear airsofters' knowledge on real guns apart from just learning about airsoft and it's covers the S&W M&P 1.0 Classic Pistol... "The Smith & Wesson M&P 1.0 or Classic series was introduced in 2005 with a heavy focus on the military and police market. This episode Patrick takes a look at the pistol that was derived from the “lesser” Sigma and was widely adopted by police all over the United States. The pistol even sees military use with the Singapore Armed Forces. This particular example is chambered in .40 S&W, but there are variants in .22LR, 9mm, .357 SIG, .380 ACP, and even .45 ACP in one form or another."
