sounds like you settled on the 23. congratulations; i hope you enjoy it as much as i enjoy mine. i carry mine in a galco summer comfort. this holster is very concealable and comfortable for me. every now and then i carry in the uncle mike's kydex paddle, usually when i don't plan on doing alot of running around that day. the neat thing about that holster is it will fit all three of my glocks - the 27, 23 and 22. what works for me may not work for you, though. i'm 5'11" and about 230 lbs but my diminutive girlfriend prefers the same mode of carry with either the galco usa or summer comfort, so go figure. i hate to be the wet blanket but the fact is you're probably going to have to experiment quite a bit 'till you find the combination that "clicks" for you. trying the holster on in the gun store (if they won't let you try it on with an empty pistol, shop elsewhere and tell 'em why) will help weed out the truly horrid ones but you've gotta wear a holster for a while to decide if it's right for you. leather holsters will also take a little while to wear in right. it's actually not that uncommon for people to spend as much money on holsters as they did on the gun. try several modes of carry, types of material and manufacturers and you'll start to get an idea of what you need. good luck.
