I prefer arched mainspring housings to flat; however I'm tempted to try out a wedge mainspring housing. Just curious to know if anyone's compared the arched vs. the wedge in terms of feel and shootability -- if so, what were your thoughts?
I prefer flat with the long trigger aka original 1911 style. I believe after several attempts with different combos of arched and flat, this works best for me. I think each hand is built different and no one way is perfect.
It's my understanding the arched mainspring housing was introduced in order to counter the tendency of some shooters to hit low. I have rather long fingers, so I have a long steel trigger and steel arched mainspring housing, both for the fit in my hand, plus the steel MSH makes the muzzle feel a bit lighter to me, which I prefer.
My 2 1911s have checkered wedge MSH. I find it really helps in placing my small/medium size hand up high against the grip safetly. I had an SA mil spec with serrated arch MSH and I couldn't grip the gun well enough. Maybe the checkered arch MSH would yield the same result (or close) as the wedge one.
