Im a massive sucker for super aggresive texturing. my favorite handgun is the M&P 2.0, if you held one you know exactly what im talking about lol. The PPQ felt like holding a wet soap bar. The grip contour was amazing felt really great but that texture man it was awful. With the high bore axis it ended up being so snappy i didnt enjoy shooting it against steel frame pistol or my M&P. The PPQ SF would probably have solved this issue too for me with grip pannel you can get whatever you like.What didn't you like about your PPQ? I have both the "plastic" and SF PPQ Q5 matches and love them both. What is so much different between the PDP and the PPQ that it's worth the switch?
Anyway that new grip texture, the optic ready and having that amazing PPQ trigger again are all good reason for me to grab the PDP. Ill see how it hold up againts my M&P shortly enough. If not so well it will show up on the EE in the near future lol. If i was in your postion with a SF Q5 id probably sit tight for a while and try to handle one, they seems great enough to not throw money at the PDP right away lol
