The BUL M-5 is a.45 ACP pistol made by Israeli firearms manufacturer BUL Transmark.
Based on the M1911, M-5s are made in "carry" models for personal defense and "competition" models for sporting use (particularly IPSC competitions).
The BUL M-5 is specifically designed to compensate for the 1911's heat absorption in high temperature environments with a polymer frame.
BUL also provided the polymer frame to other firearms manufacturers for production of Springfield Armory, Kimber Polymer and Charles Daly Polymer 1911 pistol lines.
