I'm a big fan of Kydex paddle holsters....I have 3 Blade Techs and 1 Fobus.
These don't conceal as well as an "in the pant" holster....I did have one for a Berretta 85F...I didn't like it, not real comfortable...plus I had it slip a few times.One day in a Home Depot...loading some 2x4's....I had to catch my gun before it hit the floor...Not good!!! I never had a Kydex paddle holster slip.
I have a nice Galco leather belt holster...very comfortable..good retention but eventially the leather does stretch.
I also have a break-a-way vertical shoulder holster that I'll wear very very rarely...Looks cool, but not very practical...anybody that has any real training with personal protection tactics involving drawing from concealment..knows these actually suck.
What do you use?
