WILSON COMBAT - 1911 MAINSPRING HOUSING

This MSH was a perfect drop in fit for my SA Operator AOS .45acp. No fitting required. Good price for a premium part from WC. 30lpi feels good.

No fitting required for my Colt O1980 XSE dropped right in. Tight fit. Replaced the stock poly housing with straight serrations. This Wilson Combat unit feels and looks way better.

Good part, as all of the Wilson Combat parts that I've used in the past are, BUT, like most parts on a 1911, it is not necessarily "Drop-in", although that is what the packaging states. It took about an hours worth of filing and stoning to get the OAL short enough to not bind on the grip safety. Checkering is clean and fine, finish is a matte blue.

I purchased several items including complete spring kit & other Wilson's combat parts such as bullet proof firing pin, bullet proof sear, SS mainspring housing, bullet proof extractor, bullet proof sear spring, several weight recoil springs. I don't know the 1911 as well as I do the AR and AK so I sent all of my parts to robar to have them NP3+ which has given me excellent performance so they put all of my parts together and I couldn't ask for a better running 1911. https://www.youtube.com/channel/UCD8DL8Mpc77Il7-NFUVVtWA

This is a great product as is to be expected with Wilson Combat, especially their Bullet Proof line. It does however need fitting for my Colt Rail Gun. As another reviewer stated, it is just a hair too long to fit. It should be understood that very few parts are actually drop-in on a 1911 and this is not advertised as such, so no need to drop the rating because of it. The part looks and feels great.
