I was wondering if anyone here has a milt sparks PMK OWB holster for a S&W J-frame? If so how well does this holster conceal this gun? I'm going to order one for my S&W 340 M&P and plan on wearing it under a T-shirt or polo type shirt. Is this a bulky holster or is it a thin holster? If you own a Sparks PMK could you post a pic of how it,so I can see how it carries and holds the gun against the body? Thnaks for any help on this guys.
