Perfect fit
Couldn't believe Kimber uses plastic MSH in all there 1911s. Yeah I replaced it with this W/C aluminum MPH in my custom Kimber. No fitting was needed. Looks and functions great. Kudos to W/C for all their great products.

Fits Better Than The Plastic Mainspring Housing
MSH slid right into my Kimber Gold Match II.

Perfect For Colt 1911A1
I installed this into a Colt 1911A1 Series 80 - fit absolutely perfect! No fitting, filing, sanding - nothing, just slid it right in. The checkering on the back is really nice and will definitely help keep things steady. Top quality - Love it!

On A Para X 1911 Ltc
Required about 20 minutes of fitment, looks great and feels great. Peace of mind of mind over stock polymer MSH, which is prone to breaking if firearm is dropped, on my carry weapon and its lighter than steel.

Works Great In My Kimber Stainless Target Ii 9Mm
Was replacing the mainspring in my Kimber Stainless Target II 9mm and busted the cheapo plastic mainspring housing. Bought this mainspring housing. Required a little filing to get it to fit, but otherwise is a solid upgrade from the factory housing. Filing was required to allow the grip safety to work correctly. Probably 2 minutes of light filing. Now works great. Looks great. Very happy

Perfect Fit On Kimber
Dropped in on a Kimber Custom II just great! Feels so much better than that crappy plastic one that Kimber had on there! Highly recommend this part. Thanks Wilson!
