The Thompson Custom 1911 frames are machined on high precision computerized machinery from a 420 stainless steel casting. The slide is machined from a solid stainless steel billet utilizing specialized tooling to reduce set-up and refixturing. The combination of high precision equipment and fewer set-ups result in a higher quality and more consistent final product at a lower price.

Front and rear sights are black with serrations and are dovetailed into the slide. The ejection port is flared and the slide has front and rear serrations machined at a slight angle. The mainspring housing is checkered and the frontstrap is machine checkered at 20 lines per inch. Additional features include an adjustable trigger, combat hammer, stainless steel, full-length recoil guide rod, extended beavertail grip safety; extended magazine release; checkered laminate grips with a Thompson bullet logo inlay and a checkered slide stop lever.
