Well first off I carry my P95 only in the winter. It is harder to carry then my Glock 20 with 6inch barrel but this holster helped a lot.

It is the only holster that seemed to work well and didn't cost over 30 bucks. The inside the waist makes a big difference but you can still see the grip of the gun when sitting and no light jacket.
I carry my Glock 27 for deep concealment and nobody is the wiser ever! It is the grip of the gun that matters more then anything, not the barrel length or width of the slide(large revolvers of course are not part of this equation).
For a semi auto 9mm I really don't think you can beat a Glock 26 or maybe a 19. I know others will say "Glock Boy" but my Glocks are the only semi-autos that have never jammed on me after thousands of rounds through each. Knock on wood! My Ruger, S&W and Springfield 1911 and Bersa (last two I sold because they were very picky with hollowpoints) have all jammed at least twice and some over 20 times and none of them had over a thousand rounds in each.
If you want something thin and single stack the LC9 seems like a good choice. I like sub compacts with a little more weight and I would look at a Springfield XD for that price range. My buddy is a LEO and carries the full size on duty and the sub compact off duty and has had only a few jams in over 20,000 rounds on his full size. Also other then my Glocks my S&W semi auto has been the next most reliable semi auto that I own.
This is just my 2 cents. Glocks are simple good guns that's it. They are not fancy 1911s and they won't feel as good in your hand as many guns but they go bang.
Try an XD If your friend wants something with a little more weight and capacity then a single stack. They can also cost 100 dollars or more less then a S&W or Glock not to mention a sig and the are still great guns they feel great in your hand. I like them at least.
