At one time I would have said Glock...just because I thought they were overrated. I used to think Glock was the Apple computer of the gun world.
But now I want a Glock. (I will never buy anything marketed by Apple though EVER)
I would buy almost anything for the right price...I've never had a really bad lemon of a gun...and I've owned and shot Rugers (TONS of them) Remingtons, Savages(tons of them), Mossbergs(tons of them) Winchesters, Llamas, J.P. Sauers, Antonio Zolis, Marlins etc.
Only thing I can think of that I wouldn't buy even for a couple of bucks is a zip gun....
