    It seems most new 1911 type pistols come with flat main spring housings. I've always preferred the arched. I've had this 1991 Commander in the safe since I bought it new around 1996 and had the late Joe Bonar of Novak's install lo-mounts and do a trigger job. While I was at a gun show in Dulles, VA picked up a arched MSH and a spur hammer, strut, and pin from a gentleman who had bins of old stock parts for all things USGI. I've always liked spur hammers more than rowel-type for the 1911. Anybody else prefer arched housings? Before and after pics below. IMG_2099c.JPG IMG_2101c.JPG

    I prefer an arched housing with a short trigger, much like the original 1911-A1 spec.

    Arched mainspring housing with a medium or short trigger fits my hand better than any other pistol.

    I installed arched MSH's to get my 1911's to point more like a full size Glock. I stopped shooting 1911's 'till the light bulb finally came on.

    Joe Bonar, God rest his soul, did a fantastic job on my GM 1911. Took off the sharp edges, installed a rowel type hammer, installed Novak sights, did a trigger job. About 25 years ago.

    I like the arched mainspring housing. Tried the flat housing but my hands were just not made for it.

    I think the arched MSH look more 1911-y, but the flat is more comfy in my soft baby hands.

    Straight for me. Obviously this is a matter of personal preference, this is not a matter of right and wrong. Except, everybody who likes the arch is wrong.

    Long trigger, flat MSH here. I will admit to favoring G.I. and "rat tail" grip safeties -vs- beavertails as well as preferring spur hammers on 5", and "traditional rowel" hammers on commanders.

    Best thing about 1911's is everyone can get one they like with a little effort. Good times.

    The original 1911 had a flat MSH.

    Although I love the look of the flat mainspring housing, the arched MSH and a long trigger fit my "ham hands" better.

    I absolutely can't abide a short trigger. My hands are too large. I usually wind up having to go with the thickest grips I can find, and/or grip spacers. Even then, with a short trigger trying to put the pad of my finger on the trigger would result in all the joints of my trigger finger bent at ridiculously acute angles, and the second knuckle of the finger sticking way out from the side of the pistol. I generally go with triggers with the longest shoes I can find.

    As for the MSH, I always thought I preferred an arched MSH because that's what I though 1911s should have, and that is what the first one I got had on it. Recently I bought a government model 1911 with a flat MSH and I am finding that I prefer it.

    I find the arched MSH very comfortable to hold, but I guess I'm just used to the flat version, so common on modern 1911s. Most of my guns have flat, but several of my A1 patterned guns have arched and I've left them original.

    Flat for me :)

    Short round hammer, too. I don't have much occasion to cock or decock a 1912 style much, and racking the slide dosen't need a hammer spur, so I would rather have it out of the way :)

    The great thing about 1911's is the ability to tailor them to our liking.
