Brownells USA Could be of better quality 27/03/2017

I gave this product a 3 star base on 2 factors, quality and value.



First off for the same amount of money, i am sure there are better quality MSH out there. When i first got it, i ran my titanium mainspring cap up and down the plunger hole and i could feel the grittiness, so i thought lets put some lube in and install it and see how bad. Well it was fairly bad to the point that i could see the hammer hopping. So i removed it and use the 2000 grit sandpaper on a dowel trick and smooth it out. Reinstall and voila, now the action is smooth.



This product was made at the maximum spec, so there may be fitting required on your frame, mine took about 10 passes on the underside of the 2 ridges for it so that the pin hole lines up at the bottom. Also, the pin hole at the bottom was not reamed out perfectly, what i mean by that is that none of my pins would go in at all, so out comes a round file, 5 passes and now the pin goes freely across.

Definitely recommended

Brownells USA Fusion Main spring housing 04/06/2016

Work excellent for Colt 1911 Model 1991, no additional fitting required. 100% drop in accuracy.
