Dan Wesson PM9 if you can find one. They are just making 30 of them this year. I'm waiting on one on order now.

I qualified with my father's Kimber Stainless Target II and it was a great shooter, very little recoil and very accurate. As for size, I think it's a bit overkill for a 9mm. Good gun.
 
Aren't there reliability issues with 9mm on 1911 platforms that werent designed for that particular round? EMP was built around 9mm so it doesn't fall into that category. This is just what I've heard, no first hand experience. Might not really be a problem.
 
I have had a couple of 9mms, one a Gov't model, and one a lightweight commander. While both had some cartridges that they disliked, both had some that they just dearly loved, both reliability wise and accuracy wise.

So, with the caveat that ammunition must be tested, I would not be afraid of any 9mm 1911 type.

I seriously doubt that Colt engineers would have introduced a 9mm Commander and Gov't model if there were any major reliability problems.

I still prefer the longer cartridges, but reliability is not the reason.
 
I don't think you'll see many reliability problems. 9mm is a straight wall cartridge just like the .45acp. It has plenty of power to operate a full size 1911.
It will be as accurate as you are although that can be said of any good quality pistol from Sig, CZ, Beretta, S&W, Glock, Springfield, etc.
I am partial to CZ autoloaders and don't care much for the 1911 but its more personal bias than anything. If you like the 1911 in 9mm, buy one and enjoy the hell out of it.
 
The main problem is the older magazines. The 9mm is shorter than the .45 and there is gap in front of the round to the end of the follower. The slide hits the back of the round and it dives in the magazine.
The new mags from Wilson, Metalform and Tripp have pretty much solved this with followers that wont dive as much as the older magazines and a spacer behind the round to move it forward in the mag.
The other problem is the weaker recoil spring in 9mm 1911. Depending on the gun you could have a 9 to 14 lb recoil spring. At the lighter end fame to slide fit and pressure from the magazine spring may cause problems with going back into battery or ejecting. Go too strong and you'll get stove pipes and short cycles. Wilson seems to have stronger springs than the Metalforms and causes slide drag issues in one of my guns.
When you have one that works, they are ton of fun. :)
 
I've got a Springfield full-size 1911 in 9mm. It's soft-shooting and a ton of fun. I have both the newer and older style Metalform mags (some have the spacer in the back, some have a crimp in the front) but it's reliable with all of them.
