As you may remember, I bought a new Gen 3 Glock 22 a week ago. I've since put 100 rounds through it. Long story short, I'm not liking this gun very much. I knew I should have gotten something in 9mm or maybe .45 ACP. I'm now considering selling it. How much is it worth? I'm thinking around $430-$450. Am I at least in the ball park?
