Optics have been placed on competition pistols for decades, but the understandably hit or miss reliability of tiny electro optical devices placed on rapidly accelerating and decelerating objects with significant mass has been a stumbling block to their adoption in the tactical or military sphere. With the accelerated development of micro red dots like the Trijicon RMR 2.0, Docter Optic, and Leupold Deltapoint Pro demonstrating that little red dots are finally ready for prime time, it has become in the last few years almost a requirement for pistol manufacturers to sell optic-ready versions of their pistols.
Along with the rise in the popularity of micro red dots on pistols, there has been increased demand for pistols designed for use with sound suppressors (or silencers, if you’re old-school). Sometimes this calls for more than simply machining a threaded barrel and leaving the rest of the pistol alone.
Enter Walther Arms and their new PPQ Q4 TAC, a pistol made specifically with optics mounting in mind. An out-of-the-box pistol meant for mounting both a silencer and a micro red dot is still something of a rarity even with increased demand for such things, but Walther has apparently had their ear to the train tracks, because they clearly know which way the wind is blowing. The PPQ Q4 TAC – quite a mouthful – is a suppressor-ready, optic-ready, duty-ready, American style mag release version of their excellent PPQ pistol line.
Most shooters used to gritty and creepy striker pistol triggers should be very pleased with the clean and crisp break of the PPQ Quick Defense trigger and even more pleased with the short and positive reset. It’s everything people have been seeking in a striker gun trigger without the expense of aftermarket modifications or the lingering self-doubt regarding the effectiveness of internal safeties after said modifications.
Atop the matte Tenifer finished slide is a removable rear sight plate with a fully adjustable LPA rear iron sight. This plate may be removed and replaced with one of three optic mounting plates included in the box with the pistol: one meant for the Trijicon pattern, one meant for the Docter Optic, and one meant for the Leupold Deltapoint Pro. Also helpfully included in the box are the screws and tools and other hardware required to mount these plates and thus their intended optics. Out front is a fiber optic sight for rapid sight acquisition in daytime use, although it won’t be usable or necessary with the rear sight plate removed and a red dot optic in place.
The muzzle is threaded ½ x 28, the standard 9mm threaded barrel thread pitch, for use with silencers / suppressors. The recoil spring installed in the pistol from the factory is designed for use without a silencer, while a spare recoil spring in the box is meant for use with a silencer.
Little touches like this extra recoil spring and the inclusion of three magazines – two 17 rounders and one 15 rounder – are sure to set the Walther PPQ Q4 TAC apart from the competition. It’s obvious that Walther thought this package through before taking the best parts from all of their PPQ models and combining them with an optics-ready slide to make a pistol that will shoot just as well as standard models while offering flexibility which was previously available only via expensive and time-consuming aftermarket modifications.
