I have the T1C Axis Elite, and I will say it makes for a very fast draw - like a hot knife through soft butter. By far the easiest to draw from, of all the IWB appendix holsters I've tried (which includes ones from Crossbreed, Alien, We the People, G-Code). Printing isn't bad, although I've yet to find any that don't show, even using a claw to press the butt closer to my torso. I realize most people don't notice, but to me it stands out like a sore thumb; I'm fairly lean, and it just seems to jut out, no matter what. :(
Anyway, back to the T1C... For me, wearing it for hours isn't very comfortable; seems like it cuts into my body. I'm typically just in t-shirts; if I wore an undershirt or had something between the holster and my skin, it'd probably be a lot better.
So far my favorite is the G-Code Phenom Stealth. It's the most comfortable (thanks to the "tactical fuzz"), and also amazingly prints the least. Just a tad slower to draw from (also thanks to the fuzz), but the comfort is worth it. Does not have attached mag carrier, so you have to have that separate; not a huge issue to me, but the T1C made it very smooth and easy to change out mags quickly.
I liked the idea of the Enigma system, but it's not available for my gun.
