Hey all. I'd like to buy a TP9 ASAP. The only problem is that I cannot decide which generation of TP9 to go for.

If I get the newest TP9, with the extended dust cover and grip, then I will for sure do a grip chop down to P9 length. Otherwise, I'd go for the older TP9 that had the P9 frame to begin with. Were there any significant differences other frame frame dimensions between the older and newer TP9's? I seem to recall something about Kahr changing the design of the slide stop spring retention or some other.

And just to double check, this kind of grip chop should pose no problems, correct?
