I've never sold a gun because I'm pretty sure I will regret it. That being said, I'm seriously thinking of selling my HK USP 45 for a p2000sk, a Sig, or a SW1911 Compact ES. The HK is just too big for my hands and I don't like the DA trigger. The reasons I haven't done it yet are a) its scary accurate in SA b) been completely reliable c) was the first gun I bought myself (Dad bought me a Remmy 581 when I was about 9 or 10).
