Anyone who's ever tried to speed-reload a mil-spec 1911 knows that trying to get that magazine into that single-stack magwell can be a challenge. This Stan Chen Shooter Installed Magwell is designed for easy attachment onto any standard 1911 pistol, allowing them to dramatically improve their reload speeds. Each Stan Chen 1911 Magwell is available in 4140 chrome-moly steel or 416 stainless steel options and is designed to fit all standard, USGI 1911 frames. The funnel design matches the beveled magazine well openings found on most of today's production 1911s. Those who own 1911s without any kind of magwell bevel may need to do some minor fitting to optimize performance. This one-piece Shooter Installed 1911 Magwell is also designed with smooth contours that eliminate any sharp edges, and all of Stan Chen's 1911 components are machined right here in the USA.
