I'm looking to start pinching and saving for my next purchase... Including working OT as I can get it. However, it'll be quite awhile before I'll be making a purchase, so I have time to research and plan. I'm looking for home defense & maximum range fun. I have in mind two ideas and I'd like to hear folks views on both. Please own or have experience with what you recommend. A) KRISS Vector SBR .45 ACP or B) AR platform SBR in .223/5.56 with a few tacticool items like a mounted light and mounted camera. I wouldn't mind a 308/7.62/300AAC but think its overkill for a suburban environment (don't want to shoot through my neighbors houses). I really like the KRISS, I've rented it before and already own a G30 and the mags would work for my backup... So that fact goes a long way to overcome the cost differential with an AR platform. Yes, I'm aware I'll need a tax stamp, and I live in Texas, so there no state law issue in the way.
