Ok I am looking at a couple of guns now. I am looking at the Glock 23, Kahr CW9 or 40 and the Sigma series as well. My question is this, will the Glock 23 be easily carriable once I get my CCP? I know the Kahr will be easily carriable as it's a touch smaller. Talked to the wife and she's ok if I push the limit up to around $500. Also which would be a better round the 9mm or the .40 S&W?
