V3 is DA/SA. If you don't like your LEM, I'll trade you for my V3 in a heart beat.I have the p30 so it would be my choice, however I would recommend the sa/da trigger rather then the v3 or LEM. I'm still working out the very long pull of the trigger and is sort of hindering my accuracy. But 500+ rounds with no failures.
I doubt they'll be making a CT grip for the P30 any time soon, but you never know. Here is the new CT system that the SEALs are going to be incorporating into their new HK45C's (they aren't available to the public yet)...Honestly, the only thing holding me back from the P30 is that I would really like to have Crimson Trace grips on my CCW. What are the chances of them coming out for the P30? Seems like they would be difficult to engineer for the grips on that gun.
