I am told that the new PPQ has a Tenifer treated slide. Interesting, no? I thought I would look them up.
I am unfamiliar with the new Walther PPQ. I do know that it is the successor to the P99 and I know there were a lot of fans who swore by the P99. However, I did have the opportunity to shoot a P99 previously. Personally, I didn't see anything remarkable about it, although I didn't find anything wrong with it either. I am told that I would have preferred the later P99QA.
However, in my unscientific initial preview of the PPQ, I am astounded by the physical length and positioning of the slide lock/release! (click on the pic to see a larger version)
Holy cow that is long!!! And it is presumably on both sides. And wow, does it have enough slide serrations?
Some folks don't like the big square trigger guard, but I do. Definitely would work with gloved hands. Anyway, I know these are aesthetics and personal preference, but I thought I would share in case you hadn't seen one, or noticed the super-long slide lock.
