Arched with a lanyard loop, as well as a short trigger.

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).

Straight fits ME better.

My combat commander and Gov't Model are both straight.........and that's how I like 'em.

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.

Prefer straight, but can do about as well with either, though I tend to throw shots a little high if I get in a hurry. Also prefer short trigger in spite of having fairly large hands.

I only have experience with straight ones. Been thinking I'd like to try an arched, as they look comfortable, and I have large hands.

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.

:) I voted for flat. It just feels better. Don

+1 for the arched/ lanyard loop and a short trigger.

Arched. If you look at a Sig, which most consider to be a comfortable gun, it has a bump down where the arched MSH would be. The newer plastic guns with grip inserts also are not flat.

I found with an arched main spring housing I get shooter's-palsey, so I have to use a flat msh. Sure I could wear padding pistol shooting gloves, but I couldn't wear them all the time so for SD I opted to modify the 1911A1 for my hand.

Colt series 80 with steel [straight] MSH
Kimber UCC II with plastic [straight] MSH. Didn't realize that it was plastic until I dismantled the gun for cleaning.

I start out with an arched. Then I file it down and sculpt it until, when I establish my grip, the sights line up straight across on top. The I rechecker it with 20LPI checkering.
What I found is that the flat gave me a sight alignment where the front sight was slightly low. The arched made the front sight slightly high in addition to making me fail to fully depress the grip safety. So I figured, I have files, I have checkering tools and most important a couple of extra arched mainspring housings in case I screwed up.

I started out on the arched MSH in USCG boot camp in 1979. I though that was the way it was supposed to be, and my personal gun purchases reflected that.
Then, in the mid 90's I bought a 1911 with a flat MSH and realized I had been an idiot. The flat MSH was so much better that I've never looked back. At about the same time, I discovered the short trigger and that also become incorporated in my 1911 preferences.
I (and most of the 1911 world) have come full circle back to the original design as John Browning first created it.
