I've got a bag of holsters. And I had something reinforced a few days back about them:
It being a quite warm day for this time of year, I used an old Fobus paddle holster to carry to the outdoor range.* And when I went over to the pistol side for a bit, I tried a bit of draw & fire.
Well, it wasn't good. I've been using a IWB holster for all my belt-carry for years, and that's what I'm used to drawing from. The little bit of further out and not-as-solid difference made drawing clumsy. And slower. And a bit scary. NOT confidence-inspiring at all. So back to the IWB, at least until I can save up and get one of Michaels' rigs for OWB, something that'll keep it in tight as I'm used to.
*Shut up; long-ago purchase. And it was handy at times
