Perfect fit

Great upgrade to your 1911. Simple, easy install. The housing is bare; you'll need to install the pins and springs from your other mainspring housing. This housing slipped right into place with no additional effort. And, it looks great.

Great fit

Bought one for my Kimber pro series and it fit like a glove with no modifications. Had it a few years and i will be buying another for my colt competition. Very durable and zero issues. Not to mention it looks and feels fantastic. Gives good grip without being overly abrasive on the palm. The value is the main selling point. I was afraid when i saw the price but after getting it i realized the other manufacturers are just marking things higher than they need to be. Will buy again
