I carry a Sigma 40ve in the winter and really appreciate the large round count in 40 caliber. In the summer I'm outside in a t-shirt all the time doing physical labor and the Sigma is just too large. For that reason my summer EDC has been a Kahr CW9 but I feel a little less protected with eight rounds of 9mm, go figure. I think this is going to be the summer when I try a Ruger SR9 with 17 + 1 rounds of 9mm. I don't think I would feel undergunned with this much 9mm in a four inch barrel.
