The Middle Aged Gamer checks out the SIG Air Proforce P320 X Carry GBB Pistol in this video review. The Proforce airsoft pistol is modeled after the SIG SAUER P320 XCARRY and replicates its advanced ergonomic design, including the straight blade trigger and XSeries grip module. It has a fully enclosed, high volume blowback system, a revolutionary hop-up system, and is field strippable like its centerfire counterpart. The pistol also has superb attention to detail with engraved slide and authentic stippling and SIG SAUER markings molded into the grip module.
