I've put 500 rds through my new XD45 in the last 3 weeks and have nothing but praise for it. It feels great in "my" hand and I've been almost as accurate with as I am with my Sig P229.
I'm impressed with the finish thus far, but this thing is still a baby regarding how many rds I've put down range with it. I'm sure I'll have more to say about it in a year or so.
Before I bought it, I had looked at and held various Glocks, the HK P2000, the Walter P99, the Sig 2022, and some other sigs. The XD45 felt the best for me. Caveat - The HK was my second choice, followed by the P99. I really liked the Glocks and would love to own one, but they just don't fit my hand as well.
