I wasn't familiar with the urban carry holster so I just finished checking out the website. while its an interesting concept, I'd stay clear of it myself. For one thing, it appears to require two hands to draw. Also, it might not be possible to draw it from a contorted position, such as bending forward or maybe even seated.
Best carry method for you will depend mostly on what gun you carry and how you dress.
I understand a belt holster may not be possible for you if you wear a tool belt daily. So a few other options to consider:
-- Pocket carry is a nice option for ultra compacts like the LCP, Kel Tec, etc.
-- Some guys like ankle carry; might be something to think about.
-- I frequently use a belly band holster ( Desantis) that I'm quite happy with.
-- under heavier clothing a shoulder holster is a nice option for all day carry. Bianchi makes a nice one.
Oh, and welcome to the forum!
