Leather pocket holster

I think I've seen an article or two in American Handgunner, where Clint Smith said he pocket carries an N-Frame from time to time.

I believe he's listed pocket holsters from Mitch Rosen ( https://mitchrosen.com/products/holsters/pocket-holsters/ ) and Milt Sparks ( https://www.miltsparks.com/products-pocket-holsters.php ) though both only show J-Frame type guns on their websites

While not leather Mika makes a good pocket holster. I have one for my L frame.

Mikas appear bulky when they arrive, but they conform to the gun and your leg in a few days.
Good stuff.

I pocket carry and have 2 Mika holsters and recommend them highly. I've never had an issue in regards to them adding bulk. Excellent quality and reasonably priced.
