Congrats!!! That's a nicee snag! I got one a little over a year ago and I love it. It's a lazer!

You can get 10 round mag extenders and some really nice ammo from a site called Elite Ammunition. I haven't done either of these yet but its high on the list. A ton of info and a nice user group sponsered by eliteammunitons.com is fivesevenforum.com.
