I've had a Galco Escort since 1996. It's not my usual daily mode of carry, but it does get pressed into service for certain circumstances. For example, it's the best way I've found to carry while on my motorcycle. My gun is easily accessable, doesn't get flashed when I take of my jacket, and the bag blends right in to the rest of the black synthetic gear I wear. I also like it for time when I'm wearing gym shorts and the like, which don't offer enough support for another type of holster.
I've never had a single person "make" me while I was using the Escort. The design of the Escort allows you to pull the gun compartment open very easily rather than having to unzip it. It's really pretty fast. It carries the gun and a spare mag, plus it has enough room in the non-gun compartments to hold wallet, keys, change, etc...
