I have and often carry a Colt Defender, which has the 3'' bull barrel. I have had one malfunction in nearly 500 rounds, 100 of which were JHP carry ammo. Most of the reliability problems I have heard of in 3'' 1911s were from other manufacturers.
I recently bought a Kimber Super Carry Pro with a 4'' barrel, and once I get enough rounds through it, it will become my daily carry. It feels perfect in my hand.
The Kimber has a curved (bobbed) grip so the Defender loses a bit of its shorter grip advantage, and it will hold one more round than the Defender.
For me, the grip size is a bigger deal for CCW than a 3'' vs 4'' barrel (at least for 1911s).
