Analysis

The Model 4003 employed an aluminum alloy frame combined with a stainless steel slide, resulting in lower weight compared to the all-stainless Model 4006 while retaining full-size dimensions. In the current handgun market, standard Model 4003 examples appear less frequently than TSW variants. Earlier production runs typically lack metal injection molded parts found in later TSW models. Magazines for both versions have become scarce on the secondary market, often commanding higher prices when available.
