Here's something to think about:
Clint Smith says it but it's easy to gloss over. He says your holster should give you a FIRING GRIP. (emphasis mine). IOW if you have to re-adjust before you put the front sight on target, then you have the wrong holster, wrong belt, wrong wear location or something. It should, of course cover the trigger, b/c you could shoot yourself in the jewels or something being excited.
Look at what three-gun shooters use. They have that for a REASON. (partly it's to assure the safest possible re-holstering, but also speed of acquisition of the firing grip).
It's the best of all possible worlds, b/c it gives you a secure, 'straight on' full firing grip. If you COULD, you'd wear that (a little less glitzy of course). But we can't, we don't want to excite people, and it would be cumbersome to a degree. It's better than drop-leg, but in combat you'd snag it on stuff. See my point, though.
(I'm talking about the offset from the belt).
So holster makers should assure you can get a firing grip and in reality to optimize, they should sell the holster and (a) belt combo together. You want no give, or wobble or missing the holster when not looking. Concessions have to be made for your mode, which is CC, for example.
You could CC outside the pants but under a loose jacket. In MOST states or many, conceal is specifically defined...well, let me back up. IF your state defines 'conceal' as 'out of ordinary view' you should not endeavor to hide your defensive tool under three layers of shirts and sweaters and coats and jackets, if you don't have to.
But too often 'we' don't look at what's required and therefore make 'amateur' decisions. That's OK, because we 'are' amateurs. But we can try to think and understand the code and get better. We shouldn't have a lenient CC law and make things difficult because we are 'nervous' and have to have 'no trace' or have to wear tight shirts because it's 'fashion' I mean are you seriously carrying? Do you have serious threats.
Nuff said. Sorry to be long.
