I have a Springfield MilSpec and I've been wanting to swap out the factory arched main spring housing with it's goofball internal lock for a flat msh. I have put together a number of options a dozen times on the Brownells web site, but for whatever reason I never bought the parts. I was on the Ruger site trying to decide about a few things for my 10/22 when I decided to look at the SR1911 parts page. I ordered a flat checkered msh for $20, the spring $2, the caps were $2 each, as was the retaining pin, while I was there I bought an SR1911 trigger as well ($16.00).
After adding in shipping all of the stuff combined was like $50

I have a couple of eclectic Gov't models as well.
There is a Smith & Wesson flat mainspring housing in my Colt Gold Cup, and several small parts in my Caspian and DoubleStar frame builds.
Now Ruger is another source. Multiple sources of suppy are good. So far I have had good luck with the open source approach to pistol building.

I've bought 1911 parts from Wilson Combat, Ed Brown and Fusion Firearms with good success. Brownells is good but don't care for Midway.

Well, UPS says the stuff should be here tomorrow. I'll do the MSH swap and put a few rounds through it before I swap out the trigger, but I may just test fit the trigger as long as I have the gun apart.

The parts came today.
The MSH went in with just a little trouble. The main spring cap pin hole in the main spring housing had a burr on it that needed to be cleaned up before the pin would fit in the hole, but other than that I think it came out pretty good
I have not yet done the trigger. When I had the gun all the way apart I did test fit it and it seemed to go in with no issue, but there is an over travel screw and I don't have an allen wrench small enough to fit it, nor have I read up on how exactly to adjust an over travel screw, so that is going to have to wait a bit.

I decided to install the trigger, I'm just not going to do anything with the over travel screw until I know more about how to adjust them (That's safe right, leaving out the over travel screw?). I also put the cocobolo grips back on. I like the way these two mods came out. Total cost including shipping for the main spring housing parts and the trigger was like $56.00.
