While looking into a 3" .45acp 1911 at my local gun store the other evening, I came across the STI LS.
Specs from STI website:
Slide .765" thick; 1.06" across the very thin wood grip panels.
7" long, 4.4" tall, 3.4" barrel.
Capacity 6+1 rounds 9mm.

The guy behind the counter, who has always been low pressure and my favorite guy to deal with there, said he (well, his wife) has one and recoil is very minimal.
Anybody carry one? Shorter than short butt was big enough for me to get half a pinky on it (I have relatively small hands), and it is skinnier than skinny. I am not so keen on only 6+1 9mm; OTOH, the 9mm would get back on target more quickly than a 3" .45.
