I have a Sparks I-BAK for a 1911 SA Compact. It is a simple but great holster. I wonder why other holsters, unlike the I-BAK, are formed both inner and outer sides? In theory the flat inner should be the most comfortable construction.

I hope Tony will comment when he gets the chance.
Others are also welcome to express their views. The I-BAK does not seem to be a popular holster, but its pancake design, and low ride are about perfect for me. I just wish it had a body shield, but that is not an option.

I think the Axiom would profit from a flat back.
