Brownells - Installing a main spring housing/mag well on a 1911
This guide details the process of installing a new mainspring housing and mag well on a 1911 pistol, as demonstrated by Mike Watkins, a Technical Services/Pistolsmith at Brownells and member of the American Pistolsmiths Guild. The procedure involves disassembling the old housing's internal components, transferring them to the new unit, and carefully reassembling it into the firearm frame. Proper tool usage and function checks are emphasized for a successful installation.
