I'm noticing that most customized 1911s have flat mainspring housings. The gov't must have had a good reason to go from flat to rounded with the A1, but now we're back to flat. Is this a big hand vs small hand fit or what? I could maybe understand why you'd want flat if you were carrying concealed, but what other advantages would it have?
 
It all has to do with what fells good in your hand. I feel that for me, using a high hold with my thumb on the safety, the flat mainspring housing works better. Some of the new WALTHERS and S&W 's have back straps that can be replaced to make the one model of gun fit more peoples hands.
 
I also use a high hold but I prefer the arched main sprig housing.
I find It helps position my hand to the proper grip.There you go
two guys similar grip dif preferences. what ever trips your trigger.

Both my wife and I prefer the flat MSH. Smaller and more compact grip. I hold thumb high. She likes a regular lower grip.

Not that the arched does not work or is not better, we just like the flat MSH for the grip it provides us.

IIRC, the theory behind the arched mainspring housing was that it helped reduce the occurence of users to shoot low (or high) ?

I also prefer the flat MSHs though.
 
I found that with the stock rounded mainspring housing that my (1911) Colt Delta Elite 10mm aimed high and I had to consciously twist my wrists downwards to drop the front sight to point of aim.

When I switched to the flat mainspring housing the sights lined up natuarally for me. The other thing is that the grip became smaller and I was able to grip the gun better. (I wear size large gloves)

I just wish that my G20 10mm had the same option because I have the same problem with it.
