I'm considering a Sub 2000 for my bug out bag, but I'm leery of KelTec quality, or lack thereof. I've seen plenty of posts singing praises about this carbine, but mostly from folks who have only owned them a short time. So, who out there has owned a Sub 2000 for a while and/or has put a few thousand rounds through it? How's it holding up? In case it matters, I would get the Sub 2000 that accepts Sig 226 9mm ...if I can find one.
