Looks like you found a nice one(plus a few others)! I have a 17 and an 18; they serve differing purposes for me, so I never felt as though I had to choose. I use the 18 to review defensive shooting fundamentals periodically, since it doesn't have the recoil and the blast(makes it easier to concentrate on trigger control, etc.). I also use it to teach new shooters.

The 17 is for longer range target/bullseye-type shooting(I don't compete, just try to improve on my own).

I'm sure you'll enjoy your new acquisitions.
