I've had the keltec pf9 for about a year. Love it as much as a man can love a gun. I've been alternating carry in pocket, bellyband, and blackhills tuckable leather IWB. Here's the thing, just for sake of it, any who have one place in waistband without a holster and try and tuck shirt over it. Notice two things. How comfortable it is and also how well it hides. So my thing is I think a tuckable kydex would be the ticket. My beutiful custom leather holster made to fit my Crimson trace laser guard adds about 5/8's of an inch to the thickness of the whole package. So what holster do yall recommend. It has to be custom because I am a lefty and I have the laser guard. Thanks and I love this forum.
