Have been looking at geting one though not sure of I want 9mm or 40 cal   I dont have a 40 yet but do have 9mms.  Kinda nice to stay with the same round anyone got one?

To hear several of the police officers I know, the 9mm doesn't have near the stopping power of the .40.

that may have been true years ago but ammo is so much better these days I will always go with the .40 or lager for my choice

40 and 9mm are both duty rounds and are designed to penetrate the SAME distance, IMO 40 cal was a marketing decision.
Ya 40 has a little bigger bullet than a 9 and you get a little capacity over a .45 but with the right ammo and shot placement it really wont make much difference.

I have one, like it real well. Holster choices are a little limited but are getting better since it bought one. I prefer moulded ones. 9mm is my preference, never owned a 40cal.
