I want to comment about your comments on mode of carry too. In my opinion, I can sum it up in one word. Smart.I am new to pistols. Just got the security 9. I eventually want to get my ccw permit. I don't want appendix carry. Hesitant about back carry.
What's a good holster that balances not losing the gun (falling out- no back flips for me) and draw?
Mattress, shoes, holster and belt. Buy the best you can afford. I couldn't agree more.Hard to pick a holster for somebody. Everybody likes different. I prefer a pancake style outside the waist band holster for everyday carry. The same style holster but designed for tuckable inside the waistband carry when situations dictate. I usually buy one from MTR Custom Leather that can convert from IWB to OWB. Plus a couple more, one dedicated to OWB carry, and a second for dedicated IWB. All my holsters sport a sweat shield. None use a thumb strap, but instead are fitted to the individual pistol or revolver. A good fitted holster will give good retention, it will not come out unless you pull it out. Finally my holsters have a reinforced mouth.
