Micro slides are made to the tightest allowable tolerances, with barrels machined from stainless steel for superior resistance to moisture. All Micro frames are shaped from the aluminum for integrity and strength. In many respects a miniature 1911, among the most important Micro design advantages is a single action trigger with the kind of short, smooth pull that ensures accuracy and builds confidence. The thumb safety, slide release and magazine release are 1911 as well. Standard features include a lowered and flared ejection port for flawless ejection; beveled magazine well for fast, positive loading; sights are steel not plastic and mounted in machined dovetails for additional integrity. Includes two Tac-Mags and a UM Tactical holster.
