The EFS is a full-size, Government-length 1911 chambered in .45 ACP with an 8+1 capacity. It follows the Series 70 pattern with no firing-pin safety and uses a traditional bushing-style barrel for classic 1911 lockup. The dustcover is non-railed, keeping the standard Government profile.
The stainless-finished slide and stainless steel frame present a uniform stainless look. The slide adds front and rear cocking serrations and a lowered ejection port for smooth manipulation and ejection. The model is clearly marked 'EFS' on the frame and corresponds to Rock Island Armory mfg part number 51414 within the Rock Series lineup.
Sights are fixed and dovetailed: a front blade and a low-profile, fixed rear. Controls include a thumb safety and a beavertail grip safety. A skeletonized commander-style hammer and black textured synthetic grips with a 'P' monogram round out the configuration.
