Owners of the Colt Defender consistently point to its build quality as the main reason they chose it over other compact .45 ACP pistols. The carbon steel slide over aluminum frame combination gives it a solid feel without excessive weight, and the two-tone finish holds up well in normal carry use.

The G10 grips draw positive comments for texture and grip in various conditions. The Novak sight setup is considered a practical upgrade over standard offerings in this class, though some owners eventually swap the rear for a fiber optic or night sight variant. The skeletonized trigger is functional, though trigger feel on the Defender splits opinions between those who find it crisp and those who prefer a bit more travel.

The compact .45 ACP format means recoil is noticeable, and this is the most common point of discussion among new owners. Most acclimate quickly, but it is not the first choice for high-volume range sessions. Reliability with quality defensive ammunition is generally rated highly, while some owners note sensitivity to certain budget hollow-point loads.
