The SIG SAUER P229 E2 (E squared) designation symbolizes Enhanced Ergonomics which is the basis for their current marketing slogan, “A New Look and Feel.” The SIG P229 E2 is a full-sized duty handgun, yet it can also be effectively carried concealed. The pistol is short recoil operated and has a doubleaction/single-action firing system. It has a stainless steel slide on an alloy frame. The slide is wearing SIG SAUER’s Nitron® black coating along with SIGLITE® fixed night sights dovetailed into the slide — and these sights are part of the gun package (as opposed to being optional for an additional cost). Extraction has been further improved by a larger, sturdy external extractor positioned at the right rear of the ample ejection port. The slide sits atop a machined 7075-T6 aluminum frame which is black hard-coated over anodizing. A Picatinny spec rail is on the dustcover on which the SIG SAUER STL-900L Tactical Light and Laser can be installed and removed without difficulty. Fine horizontal grooving is present on the front strap. E2 grips are slimmer and more ergonomic than previous versions, grip removal tool is included.
