Paul Scarlata explained the appeal of this pistol in his July 2008 "Arsenal" feature: "With its new P250, SIG Sauer has embarked upon a novel concept in semiautomatic handguns — the modular pistol. The P250 is based on a polymer-grip module and metal frame/fire control assembly. This assembly is in fact the 'pistol,' as it bears the serial number, which can be removed and inserted into another grip module. "The P250 is available with two differently sized grip modules: small for the 9mm, .357 SIG, and .40 S&W, and large for the .45 ACP. Both are available in Full, Compact, and Sub-compact configurations with three grip circumferences … It can be ordered with either a long or short trigger."
