I've owned two Glock 19s. I've sold two Glock 19s.
I have held the P99, but never fired one. Did feel very good compared to the others I held that time. It does look/feel like a solid piece, cheers!
I myself newly aquired a gen3 glock 26, and I love it! 30 round mags. for range fun, and easily concealed. Love it!
