The R9 right hand grip has a complex shape inside, required to clear the mechanism. All the Crimson Trace grip sets I've seen carry the mechanism in the right side grip - I guess to accomodate right-handed shooters. The NAA .380 r.h. side frame is flat with no mechanism. The R9 r.h. grip would have to get pretty chunky, as would the l.h. grip to keep things balanced.
Still, an R9 with C.T. set-up would be nice. I did write to C.T. in 2005 when I got my R9S.
I have a set of C.T. grips on my S&W 686. Perfect function, perfect reliability.
RE: Liability after a shooting, I agree with riffraff. Get that CCW training under your belt and you'll be a lot more likely to make a proper decision before drawing your R9. In fact, maybe you'll think TOO MUCH before drawing. (The built-in disadvantage of being a law abiding citizen put into conflict with a no-conscience criminal.)
I'll go a bit further and repeat what my CCW trainer here in Michigan said, "If you are involved in a shooting, no matter how justified, plan on having to defend yourself in civil court even if the prosecutor declines to file any criminal charges against you." He went on to recommend that we should carry the phone number of a good defense attorney with our CCW permits! Articles I've read in the gun magazines by people like Massad Ayoob and Clint Smith seem to confirm that advice.
