mainspring housing change

Ive decided to try a flat mainspring housing in lieu of the arched in my Springfield Armory Mil Spec. Primarily for the range. I know I want aluminum or steel...no polymer. Any recommendations for an inexpensive yet quality part? The mil spec is parkerized so I'd like to use a piece that matches in finish. I've searched Brownells, Midway, Numrich and Sarco.

Just look around at any gun show. Plenty of original GI housings with the lanyard loop or aftermarket housings without.

Or you could try this link:

The only problem with some cheaper aftermarket housings I have encountered is that the hole (into which the hammer spring goes) at the bottom isn't drilled big enough to allow the housing retainer pin detent to securely lock the retainer pin. It's easy enough to cure by drilling it slightly bigger.

It's actually a relatively low-stressed part, which is why Colt gets away with using a plastic housing on some of their guns.

You might also end up having to get a new hammer strut and a plunger cap retaining pin. The last SA I swapped MSH's on ended up having a shorter strut due to the internal lock. Or maybe it was longer- I don't exactly recall. but anyway, if things don't mesh up right- look for a GI type cheap replacement strut. I don't see a need to go with a light-weight, polished, high speed, cadillac version for just a strut.

I'm going to use the words "clip" and "Long Colt" every chance I get. It grinds my gears to see new members attacked when we all know dang good and well what's being refered to.
