You know? I'd like to give that a try. After my less than favorable experience with the 509, I've been somewhat hesitant to pick up another FN pistol. Still, the one you described sounds interesting. Maybe I'll look around and see if I can come up with one.

Howard, I agree with your thoughts on the 509, there's so many better choices.
However if you like 45ACP as I do, IMHO the FNH-FNX-45 Tactical is what a modern 45 caliber should be. A 1911 on steroids. And what surprised me most is how they got 15 +1 rounds within a grip that's less than 1.3" wide and quite comfortable for my medium sized hands. Even though it has fairly aggressive stippling, I did add Talon grip tape as I do with all my polymer guns.
The SIG P220, HK USP 45, CZ 97 (and clones) are fine guns, but with or without the optic, you just might like this one!
