Getting ready to buy a H&K 9mm USP compact guys. I need so info before I buy though. I hold the gun I my right hand and would like all the controls (safety, and everything else that is on the gun) to be able to be used by my right thumb so what varient is this? Also is this gun a DAO, SA/DA, or what I'm confused as to how the gun can be both DA/SA because it dont have a hammer on it. Can someone explain this please? Also I was thinking about getting the LEM (whats the trigger pull on this). How does the LEM pull compair to the standard SA pull. Any info will be great. Thanks guys. Bigbore chime in on this.
