Here be ships passing in the night.
While our faithful correspondent Rollo is making the transition from semiauto carry to revolver, yours truly has converted from revolver to semiauto.
That's for CCW. For HD it's revolver all the way. If it's down to the last stand of home defense and I absolutely must defend my castle, the 686+ loaded with .357 DPX is the best I can come up with short of the Mossberg with #1 Buck.
For street carry and CCW defense, I'm liking 18 rounds of 9mm DPX and so far the SR9c has been flawless at the range. Still, I'm saving up now for a 638 2.5in.
