I may have a chance to get a good deal on a Walther/HK MP5 (sd style model). Anyone have experience with them? Looks like a fun little plinker-a friend is going through some tough times and will allow me first bite at a really great price-the only provision, and we've done this before, is that if I ever decide to sell it he gets to buy it back at the same price.

He's had it a couple of years and has only put about 150 rounds through, trouble free with CCI mini-mag.

Thanks for any feedback.
