I have a wonderful IWB holster that I love to carry with, but can see what an advantage it is to have an OWB holster for competition. I want something that is IDPA compatible, though that's not the only type of competition I will be shooting. Any recommendations for OWB belt holsters? I'm not opposed to all leather holsters so long as they have a reinforced opening. Right now there are two that particularly strike my fancy, though I'm not sure the second one qualifies for IDPA: The Gladiator by Comp-Tac The International by Comp-Tac Also, while on the subject, can someone explain to me the advantages and disadvantages of having a straight cant as opposed to an FBI cant for competition? EDIT TO ADD: This is for my Glock 23 by the way.
