Wilson Combat Mainspring Housing, Flat, Full-Size, Blue

Perfect..

Purchased this mainspring housing to replace the arched housing on my stainless mil-spec Springfield. I was expecting a good part, but I am amazed at the quality. A perfect fit and feel, and glad I chose the blue, which gives a nice contrast with the stainless frame with black grips. Also, with the arched housing the pistol was shooting high, this solved the problem.

Flawless upgrade..

Bought this housing to replace the factory one on my Kimber. Almost a perfect fit, only took a little work to make fit. Would highly recommend this product and any others from Wilson Combat!

Another great part from Wilson Combat..

I purchased this MSH to replace the arched MSH on my Norinco. I was pleasantly surprised to find that the housing fit into the Norinco without any fitting or filing. Just drop the guts from your old MSH, and slide this one in place.

Update..

With Springfield RO ILS replacement I also just replaced the hammer strut. ILS strut is slightly longer and pre-loads the hammer spring excessively when installed with non-ILS housing.

outstanding !!..

Just replaced the ILS housing on my Springfield RO with this one. Required the longer before ILS spring and matching non ILS cap, but the pointy other end cap for the pin retention perfectly fit. Absolutely flawless fit, finish and function. Maybe even better than original. Plus the finer cut on the checkering just plain looks cool. If this is indicative of the rest of the Wilson 1911 parts, I may start buying parts and build me a Wilson 1911 from scratch.

Massive improvement..

Just installed this product on my kimber. It took very little fitting about 6-7 smooth file strokes to work properly with the grip safety. I am completely satisfied with this product, for not much cash it improves a kimber greatly.

This Housing Market is Booming!..

Wilson mainspring housings are magnificent works of art that will enhance the feel and appearance of any 1911. They are beautifully machined from solid bar stock, the checkering is precise, and they are simple to install. I recently replaced the crappy plastic mainspring housing that came on a friends Kimber, and now it feels more like a real 1911. If you want to seriously improve the performance of your non-Wilson 1911, having a skilled smith install Wilson parts is the only way to go.

An Outstanding Mainspring Housing..

A flawlessly manufactured mainspring housing that will slide into the 1911 frame without fitting. The checkering is excellent. The tunnel for the mainspring is bored straight which eliminates binding of the mainspring.
