I have shot the Kel-Tec, PF-9, compact, single stack, very slim.....I know Kahr and KT are different in many respects, however, it was, based on your criteria, a very comfortable shooter. Trigger pull is long by design, but does break and reset very quickly. Grip angle and slim design make it easy to carry, grip and get on target. It's lighter than the Kahr, and I can't recall if it is +P rated.
Price is certainly less than the Kahr, IMHO, I've always liked Kahr, but have watched there prices "adjust" lower to attract more sales.
Don't have any other info, maybe an LC9 owner can chime in, but it maybe a bit smaller than the Elite.
FWIW, although it is double stack, my ol' S&W 6909 keeps on runnin'....
Kahr makes good stuff. Hope you let us know how it turns out.
