Variation 20

Guns that would otherwise have shipped to the USMC, used instead in parts interchangeability testing and then given or sold to Colt executives. A factory letter for one example officially names the release the "Employee Edition". Serials are scattered, with some drawn from the reserved range below 01001EGA. Notable for the model number O1070CQBP, created before the regular production blue plastic clamshell pistol was established as O1070M45 and the Custom Shop offering as O1070CQB.
