I'm just the opposite of Mercy's feelings on the Glock. Can't stand them. Hate everything about them. They feel like a brick in my hand and I would rather throw the gun at someone than try to shoot them with it!
If it's an easy carry single stack you want, I have a hard time not recommending the Sig P239 or even the smaller P290rs. The 290 is a good bit too small for my hands but I have Gorilla hands so most CC single stackers are gonna be small for me. Just something I had to get accustomed to. the 239 is DA/SA so that's a big plus. Can't stand DAO actions myself but that's a personal preference. The 290 is DAO action with fairly heavy trigger pull. Thinking around 8 pounds.
