I assume you own and are referring to a PPQ 45. It comes with 2 backstraps....the "smaller" backstrap is virtually the same size, thickness x front to rear length, as the PPQ 9mm. Take a look at post #9 in the link below. Olsoul is generally very meticulous in his specifications.chandler: I looked at the 17600 for my PPQ but, since I work with the small PPQ backstraps, the 17600 seems to be too big to hug the grip enough to assure it won't slip under use. I do like its beavertail feature, however. I've gone with the 17210 grip without a beavertail. Not sure if the 17210 could be stretched enough to fit a medium or large PPQ backstrap.
FYI. My approach was to perform an initial warm-up with a hair dryer and stretch using finger strength only. Next step was to heat the Hogue with the hair dryer until it was hot to the touch. Step 3 was the application of non-foaming liquid soap to the PPQ grip followed by one more heat application to the Hogue. Liquid soap was applied to the inside of the Hogue. The insertion procedure went smooth and quick. Started with the front edge of the PPQ inserted slightly. Pushed forward until the rear of the PPQ grip was aligned with the backside of the Hogue. Pressed downward from the top of the PPQ while applying upward pressure on the Hogue. Increased the opposing forces and the Hogue slipped into the full up position.chandler: My PPQ's are the 9mm M2 and the Q5. They each come with 3 backstraps (small, medium, large) and I use the small. I called Hogue and they just haven't confirmed their 17600 for the PPQ so we have to rely on others' experiences. Hogue thinks it will work on all 3 backstraps so I'll purchase 2 more 17600, strip the 17210 off one gun and, once again, wrestle with the 17600 in its application. If it works I'll also put it on my other PPQ and let the world know....or at least the forum....of my experience. Thanks chandler. (p.s. I, too, really like my Walthers....only wish the aftermarket for Walther was more accommodating).
The first step is to measure your PPQ M2 grip. Use the widest point from front to rear. Then measure grip width/thickness using widest point from left to right side. The PPQ m2 should measure 5.3" from the bottom of the mag well to the top of the slide....confirm that.chandler: Since we agree that the PPQ 45 and the PPQ 9mm have very similar sized grips, do you think that your 17600 grip would have stretched sufficiently on a PPQ 9mm handgun with the small backstrap to provide the tight hug on the poly grip needed to secure it well in use? I realize it's a rather hypothetical question for you but anything you can add before I purchase 2 of these grips will be greatly appreciated.
I thought about that approach but didn't want to have to use an adhesive that might remove the original texture. Ended up using strips of Velcro in "strategic" locations but always wanted a more natural rubber grip. Whatever works!
