I just got my smart carry holster yesterday I am "husky" build and I carry a Kel Tec PF9
when I look in the mirror, looks like the grip is printing thru pants will try it on again tonight and readjust holster
The best advice is to wear the holster as low as possible - 4"-5" below your navel. The belt can be higher in the back (and in any case rides up because of the slope of one's buttocks). This applies to all the brands -- Smartcarry, Lightningwear
, Thunderwear -- they all work alike and put the pistol in the same position(s).
You'll want to put the holster on over your outer shirt, so that the holster keeps the shirt from bunching and getting in the way of the draw. You can pull the tail of the shirt out of the holster in the back and tuck it in over the strap in the back. That keeps it from riding up above your pants when you bend over. Generally, slightly tighter adjustment is preferable to slightly looser.
Most people who have ever worn these type holsters find that while there can
be a bit of a bulge at the end of the grip, it's usually with a full-frame weapon. However even with a full-frame pistol, no one else sees this as something that says "gun".
It is holster wearing-height dependent, though: You can create a bulge if you wear the holster high (say, just under the belt) instead of as low as possible.
I've carried a Kahr K40 (pretty close in dimensions to the PF9, except thicker) for years, including while being frisked by concert-security personnel, and never had a problem with concealment. [Of course, the same security personnel also missed the S&W 4516 .45 in my (ex-)wife's gun purse
