So why is going to a used gun better than going with a new gun ?
I didn't really go into depth, but based on the fact that the question was about a budget gun I find that folks can generally find used guns that azre of high quality at a lower price. I recommended Police trade-ins because they are usually a high quality gun that has been maintained unlike your average boat gun that someone traded in after it got rusty.
An example would be a Glock 17 turn in that I bought as a deal with a local shop where two of my friends bought one as well, so we got them for $275 each. They came with three mags. The night sights were burned out, and the finish was rough, but they feed anything and have run reliably for years. I recently took mine up to the Glock factory while I was on TAD orders and Glock went through teh gun and replaced all the moving parts. So now my gun is new with the exception of the frame, slide, barrel, and locking block. No charge from Glock. Just a service they offer.
Cheap, reliable with good customer service.
A friend bought a used Sig 226 and another bought a Smith and Wesson 39-2 that were police turn-ins. Each was under $400 and have worked well, and these guns cost considerably more if purchased new, and they still will be working for many years to come. Mags are easy enough to find as well.
Just what I feel would be better choices than "bargain brand 'x' " or the latest model that was just releasedwith no track record. They may be picked up for a few hundred bucks only to find that it won't feed hollow points or that the cheaper cast parts broke and that the gun will be in the customer service department for repairs for 6 months.
