Straight. Checkered aggressively, as well. And metal of course. I never understood how Kimber could ever stoop to using plastic main spring housings.
 
We are shooting 1911's not "plastic Glocks".

I shoot both, but that plastic MSH bothered me. It looked like poor quality plastic, even. The color wasn't even consistent throughout the plastic piece. It was rather fisher-price looking.
 
When using an arched mainspring housing I sometimes find that I won't depress the grip safety far enough. This is never a problem for me using a straight housing.
 
I prefer straight, but I do have one with an arched mainspring housing, and it doesn't bother me.
 
I prefer the straight. I just replaced the plastic MSH on my Kimber with a checkered SS. Looks much better!
 
Arched--just too many years and too many rounds with an arch. If I shoot a flattie, all my rounds wind up about 6-8" high.

Grooved with lanyard loop, or Pachmyr with checkering. Even have an itty-bitty arched MSH on the Officer's (and kept it as it helps).
 
I slightly prefer straight with a long trigger. I have arched msh's with short triggers too and they dont bother me. Neither do the few plastic msh's I have, lots of guns have plastic msh's btw, aint just Kimber.
 
I spent quite a number of years using the arched MSH.

I modified a MSH and the frame on my Commander back in the 70's to give it a bevel at the bottom. Not as much as the current popular "Bobtail" offerings, but enough to really change the feel and enhance my point shooting capabilities (as well as my normal aimed shooting, of course).

Nowadays I simply go for a flat MSH. My grip technique and wrist lock don't require an arched MSH.

Different folks have different experiences and preferences, which is fine.
 
3 straight, the original arched in parker is in the drawer with the other spare parts.
 
Four of my M1911's have straight mainspring housings: Colt Officers Model, Lightweight Commander, Combat Commander, and Lightweight Government. Over the years I just have come to prefer the better grip I have with the flat housing. The only M1911 that still has the arched housing is an early Springfield Armory M1911A1 that I have decided to keep in its original stock configuration.
 
4 straight and 1 arched on a Colt Mk IV series 70 9mm that I bought used. I have no idea if the arched MSH on the Colt is stock or not, any ideas? I do prefer the look of the straight MSH but I really do not feel any difference between the two. I really like fat wood grips vs thin and the RoCo stippled grips with a palm swell are just the handfull I need.
 
The arched MSH is usually accompanied by a short trigger. I have only tried the flat/long combination, but both guns so equipped fit my hand and pointed perfectly, so I never tried anything else.
