I also wanted a DAO trigger as I prefer one type of trigger pull. I do like manual safeties but I wanted my CCW gun to be without one. I ultimately chose the HK P2000 with a LEM trigger. I like the 9mm and the .40 S&W. I chose the .40 S&W because it is a very good compromise between a .45 ACP and a 9mm. In the case of the P2000 I was going to have to choose between 12 rounds of .40S&W or 13 rounds of 9mm. I felt that there was not much difference in capacity so I figured I would go for the bigger caliber and the one I felt would stop a threat better. When I move this will be my daily carry gun. I may also have a P2000SK with the LEM trigger and in .40S&W to back it up as well.
