I've looked at a few of the 3in 1911 models but not been able to shoot any of them. There would be an increase in perciieved recoil since it weighs less but still not unmanagable. If recoil is a factor, you may want to look at the 9mm versions by SA, Para, Colt, or STI.
The STI Spartan is a bare bones 1911 in 45, 40, and 9 with 5, 4.25, and 3.5 in barrels for around $6-700, while the Trojan and Ranger models are the same size/caliber with more features, and added price, around $11-1500. The Para's are either SA or LDA single stack or a ten rounder. It looks a little fat but is pretty comfortable and I have small-ish hands. SA has the EMP versions and Colt the New Agent. the New Agent has a sight rail instead of a rear sight that would take a little getting used to.
All of them have a 45 version too. Another slim small frame 45 I have shot and did like a lot was the Glock 36. It's a single stack(6+1) mini-Glock, with the 30 being 10+1 and fatter. I've eyed the Kahr K/P/CW 9, 40, and 45s but have only shot the P9. It was pretty easy and very slim.
