Walther PPQ Magwell Installation
WALTHER: My SF magwell is loose?
We just learned that the PPQ SF frame dimensions aren't fixed in stone the way the polymer frames are. Worse, the portion of the SF frame that we used to anchor the magwell is not controlled by the machinists in Germany. As a result, some of the magwells fit great, others not so much.
Depending on how loose the fit is, you've got options for fixing it. If it's just barely loose, you might want to shim the frame with a strip of electrician's tape (or similar), or some form of filler putty.
If that doesn't immediately sort it, we've created a special magwell that can be fitted to the frame by the end user. The tab that holds it on is left unfinished, so you can mount the magwell and use a drill to finish the tab at exactly the right depth.
We call that the "X" model, and would be happy to send you one if that's the direction you want to go.
The crosspin for my magwell won’t go in
Normally nothing has to be modified, but sometimes issues come up.
As for the type of file, there's no particular standard -- the only trick is finding one thin enough to get inside that slot. You shouldn't have to remove much at all.
Just to be double-sure, check the date code on the magwell. If it's got an "X" in it, that's the special mount version, and should be swapped out for a regular one.
WALTHER +6/+12: I only get +2!
Two ways you can end up only getting +2:
- Leaving the plastic tab on the bottom of the spring.
- The follower is catching an edge on the way down. Take the mag apart, set aside the "guts" and put it back together. Look down into the mag tube with a flashlight and see if you can see any metal corners protruding into the space where the spring/follower should go. If you see any, round them off (gently!) with a small file and re-assemble.
We guarantee everything, so even if you scratch/damage the basepad while working on it, we'll buy it back if you're not happy.
My Walther/M&P mags only take 15/17 rounds
As to the basepads stopping at 15, I need to ask some questions.
- Did you take the internal locking plate out and set it aside?
- The follower may be catching at the transition between the mag tube and the basepad. If that's the case, you can put a slight bevel on the tail of the follower and at the top-inside-rear of the basepad to allow the two parts to slide past each other -- it's the same basic problem as shown in this video about M&P mags -- https://www.youtube.com/watch?v=Tj40xkwPWiA&t=71s
- There is a possibility that the spring has rolled past 90 degrees during assembly. If so, the end of the spring is twisted sideways, blocking the rest of the spring from nesting properly. When this happens, the floorplate will want to aggressively push itself back into place when you start to slide the basepad off. The basepad will still come off, but it's a bit of a struggle.
Will the Walther PPQ Backstrap fit my P99
Yes... according to a sample size of one customer. "I wouldn't say the backstrap fit is "perfect" but it certainly looks workable!"
