Just wanted to get advice on a good AR-15 pistol in 9mm. Anyone have experience with them? I'd like to use it as a home defense weapon. So far I've only looked at RRA. Any other good AR pistol brands? I want something small (7.5 inch barrel) that I can use around the house (for those bumps in the night). Anyone have major issues with the reliability of this platform? I like 9mm...because I can shoot it at my pistol range without having to make a long trip to H&H. I recently bought an MP5, which I really like, but the accessories are very limited and expensive. AR pistols seem more practical. What do you folks think?
