Getting the right holster is the answer for concealed carry or even open carry. I’ve found the old tried and true leather holsters are still the best. Anyone that has owned and carried handguns for a long period of time has a collection.
1. Buy one fitted for the gun you intend to carry.
2. Stay away from nylon
3. No fancy mechanisms. I had trouble with one that requires tilting the weapon a certain way to extract it. Something like that is lousy under pressure. Release buttons jam too.
4. Pay top dollar and get the best you can afford and only buy once. If you buy cheap ones you’ll have to replace them anyway and end up spending the same.
This one is one of the best articles I’ve read on holsters.
