Recommended with reservations

Brownells USA Poor fit at base. 16/05/2018

The Mainspring housing fit the frame of a new colt govt with a gap at the bottom due to the mainspring housing being ground undersized leaving the sharp edges of the frame exposed to catch the heal of the hand while loading.

Not recommended

Brownells USA Buyer Beware. 07/09/2016

Fit the frame of a Colt 1911 but the hole for the mainspring cap was undersized and it stuck a third of the way in. Would have to be drilled out to work. Pretty poor Q/C.
