I hate IWB carry. Have not yet found a holster that is comfortable without buying new shorts and pants that are two inches larger then I would normally wear, and then they are too baggy. I live in Florida and wear cargo shorts or pants most of the time. Bob Mika is making me a pocket holster for my P99c, which will enable me to comfortably carry it in cargo shorts or pants. I have also found that I can pocket carry with no problem in regular docker pants.
If anyone has a suggestion for an IWB holster for a P99c that they find comfortable, I would appreciate hearing about it. Thanks.
