Description
The little Walther PP-series pistols are wonderfully compact, but that short grip leaves your pinky curling under the mag with nowhere to go. This Mec-Gar Finger Rest Set fixes that. It swaps out the flat metal floorplate on your Walther PP, PPK, and PPK/S magazine for a contoured finger rest that gives your bottom finger a proper shelf to sit on. Better hold, steadier control, and a more natural point without adding a single round to the magazine.
What the F42090SET Actually Changes
Out of the box you get a black polymer finger rest, a steel adapter, and a polymer locking plate. The steel adapter is the piece that keeps things solid where it counts, while the polymer rest keeps weight and bulk down. Mec-Gar has been building magazines and mag parts in Italy since the 1960s for a huge chunk of the firearms industry, so the fit and finish here is what you'd expect from a company that supplies OEMs. Folks who have compared these to the older factory rests note the Mec-Gar version runs smooth all the way around without the mold seam on the front face, which gives it a cleaner look.
Fitting the Walther Finger Rest Set to Your Magazine
Installation is a standard magazine floorplate swap. You depress the floorplate catch through the hole, slide off the old metal plate, then reassemble with the finger rest in its place using the included adapter and locking plate. If you've ever disassembled a magazine for cleaning, you already know the drill, and the Walther owner's manual walks through the same steps. No permanent changes, no gunsmithing.
One thing worth being clear on: this is a grip upgrade, not a capacity upgrade. It does not add rounds to the magazine. What it does is turn a two-and-a-half finger grip into something you can wrap your whole hand around, which makes a real difference during longer range sessions and faster follow-up shots.

Frequently Asked Questions
Does the Mec-Gar finger rest set add magazine capacity?
No, it does not change your round count. This set replaces the flat metal floorplate strictly to improve grip and ergonomics. Your magazine holds the same number of rounds it did before, you just get a shelf for your pinky.
Will the F42090SET fit my Walther magazine?
It's designed for the metal floorplate magazines used on the Walther PP, PPK, and PPK/S. It works with both factory Walther magazines and Mec-Gar magazines that use the standard floorplate design. If your magazine already has a finger rest, this simply gives you a cleaner replacement.
How hard is the finger rest set to install?
It's a basic floorplate swap that most owners can do at the bench in a few minutes. You depress the floorplate catch, slide the old plate off, then reassemble with the included rest, steel adapter, and locking plate. The same steps in your Walther manual for magazine disassembly apply here.
Is the Mec-Gar rest better than the original Walther finger rest?
That comes down to preference, but the Mec-Gar version is smooth all the way around and runs a touch wider than the old factory piece. It skips the front mold seam some original rests have, which gives it a tidier look while fitting and functioning the same.
