The first Bobtail I handled was a 5" 1911. I thought it sucked. I did not like the feel, balance, and it pointed way too low.
Then I fondled a 4" one a couple of weeks later. That one was way better, still not perfect.
The POINT; handguns are very personal and some people won't like what other rave about. Get your hands on one (like at a gun show or LGS) before you take a plunge like bobbing the frame on your favorite M1911. Better yet rent one borrow one and shoot it.
