The thinner the package the better. Then I got an Uncle Mikes no.3.
I've used this every day for 4+ years. Your choice of britches will make or break this dance. Short go pockets on Wranglers leave the thing peeping out the top and show a bulge. How about relaxed fit somethings with pleats?
Depends on how you style.
Another vote for the Uncle Mikes pocket holsters. They are super thin and work very well for me too.
I’ve got one for my Ruger LCP 380, one for J-frame S&W’s, and one for my Sig P365.
