Wilson Combat ACP Compact 9mm Luger 4in Black Pistol – 10+1 Rounds – The ACP is built with the highest quality parts in the same time-tested way as other Wilson Combat custom 1911 handguns, but with reduced customer selected options that streamlines the production and enables a lower price to the end user. The ACP features the latest generation forged slide, frame and barrels that are hand fitted by our skilled pistol-smiths with 100% machined Bullet Proof parts for a lifetime of high performance.
