What holster are you using for ccw purposes? What are you carrying in it and how do you like the holster? Pros and cons if you don't mind.
I use two. The Galco King Tuk and the Glaco Stow N Go. The stow n go is pretty neat. It's extremely simple to use. Just slide it IWB and it clips to your belt. And it's comfortable. And because of its size it holds the gun close to your side and it's secure. The only real downside is its tough to re-holster because it kind of closes up at the top. The king tuk I just got and haven't worn it but a few times. It's comfortable and an undershirt isn't needed. It's a kydex holster so it doesn't close up. The jury is still out on my feelings about it. I'm gonna give it a good try. With my stow n go I didn't need to change pants sizes. But with the king tuk I might have to. My pants are much tighter and not as comfortable. But it will mold to my fit over time. For my particular gun I wish it held the gun tighter in the holster. It's a little loose. But a different 1911 or any other gun it may not be like that. Of the 2, I like the stow n go quite a bit more and it's half the cost. I've worn it neat every day for a year and it's still in great shape.
Blackhawk Sherpa/Glock 19. I love the Sherpa because it's super light weight, comfortable, incredibly durable and includes a locking mechanism (single "button", which is easily released by applying pressure with the index finger). The only draw-back is that it can only be worn outside of the belt/pants.
