I think I've FINALLY found the right holster for me!!!
I started with a Fobus paddle ordered from Ruger. It works but was really only concealable under a heavy sweatshirt or jacket and I didn't feel like it was completely secure on my belt.
Next was a Pocket Holster from
www.thepocketholster.com. This is still my best option with a tucked in shirt. I changed the anti-print flap to a heavier piece of leather to reduce printing. Some jeans pockets are still a little shallow to feel completely concealed and it is not super comfortable when seated.
Then I purchased a Desanti Summer Heat IWB. This is a very nice holster for the money. It seems to be best for appendix carry (1:00 or 2:00) which is not the most comfortable position for me. It works for behind the hip (4:00 or 5:00) but the metal clip can tear a hole in your shirt, scratch your belt and scratch furniture or car seats when seated.
So... I started a search for a new IWB leather holster with snaps/straps instead of a metal clip. I ended up ordering from hanksgunleather.com. I was a little skeptical since the holster was only $40 plus $2 shipping. The holster shipped immediately and arrived in a couple of days. This is by far the most comfortable holster I've worn, standing or seated. It conceals great under any untucked shirt. There is no risk of tearing or scratching anything. I wish I had started here. The best $40 I've spent in a long time. I'm sure more expensive options use better leather, snaps, etc. but this is a great value and worth consideration.
