By now it’s apparent what Walther Arms planned years ago for the United States market: their striker-fired Performance Duty Pistol (PDP) series has become the company’s primary offering. Sub-editions of the newly popular PDP have proliferated. But there is one that I feel ranks among the best of them, one that I carry at work almost daily, that’s received little attention. That’s why we’re diving in with this Walther PDP Pro ACRO review.
Sales of this 9mm, striker-fired, German-made pistol were, until sometime in the spring of 2024, restricted to law enforcement agencies and officers. But now this standout in the PDP line is available for order by any legal buyer. It’s also been the model least covered by media. Here, I’m doing my part to change that.
On the way to explaining my fondness for the Walther Pro ACRO, I’ll start with some general information about the gun and the Pro segment of the PDP lineup. In general, PDPs are on the bulky side. Their boxy appearance is in part thanks to a fairly square slide with deep, aggressive “superterrain serrations” as Walther Arms calls them on both the front and rear. Capacity on the Pro ACRO is 18+1, compared to 15+1 on some compact PDPs. Walther bestows the Pro designation to some other full-size PDPs bearing the same trigger. The difference is, this one includes a pre-installed Aimpoint ACRO red dot.
The PDP Acro Delivers Robust, Quality Features
Two Trigger Options
Walther offers two triggers with the PDP. Base models feature the “PDT,” or Performance Duty Trigger, with a traditional curved face. The Pro line sports a flat-faced “Dynamic Performance Trigger” with skeletonized safety block.
It’s my theory, though I’ve not done a thorough takedown of either, that the differences are only external. If you’ve fired a base or F Series PDP, you have a feel for the Dynamic Performance Trigger. Their operation is identical, and excellent. A five-pound (give or take) pull is followed by no perceptible creep, an easy break, and a short, palpable reset. It is the trigger one can expect from a company long lauded for trigger quality, dating from their hammer-fired products’ history. It’s also the trigger I expect for the price, which is in the upper but not inflated range in the striker-fired territory of gun store shelves.
The Pro’s Metallic Mag Well
Like others in the PRO series of PDPs, the ACRO model includes a metallic magazine well and metal magazines with squarish floor plates. This is a difference from the non-Pro models. Those don’t have a flared mag well and have polymer-base mags with the base in the more familiar “U” shape.
Regular PDP vs Pro PDP Magazines
In the user manual is an admonition that the Pro series guns won’t run regular PDP mags. This is true since the mag well blocks the U-base mags from being fully seated. But, that (to me) dreadful mag well is removable with the simple push of a pin. Voila! My Pro ACRO now runs the polymer-base magazines. I already had some, since my first PDP was a base model and Walther generously includes three mags with purchase. So my perceived problem—and peeve—are gone.
I am not a fan of extended mag wells, especially for duty use. The added bulk tends to slow me down getting in and out of the passenger side of a vehicle on repeat, as I do in my armed courier job. For law enforcement, the metallic well, and mag baseplates for that matter, offer opportunities for undesirable clatter. They inevitably hit objects in tight quarters. Additional loss of stealth and tidy appearance is found in the way the edges of the metallic baseplates of the Pro mags lose their finish, exposing the glint of polished aluminum. These are problems in a duty gun, but the fix was easy, if not exactly blessed by Walther Arms.
Optic Setup Done Right
Every PDP is optic-ready. Walther includes a mail-in card with every model except the Pro ACRO which allows the user to select the brand footprint of their choosing. But the Pro ACRO is different, for a reason obvious in the name. The gun comes already equipped with an Aimpoint ACRO P2 optic.
The iron sights were not forgotten. The Pro ACRO is the only PDP that comes standard with tritium, in three-dot configuration. The steel backup sights aren’t suppressor height, nor would I want them to be. They’re just high enough to clear the ACRO window, making use of them in a pinch a matter of course. Tritium sights are a feature I wish Walther would include on other PDPs. Only the Pro ACRO has them thus far.
About that ACRO
Most readers likely know that Aimpoint brought the first closed-emitter pistol optic to market in the form of the ACRO. Like the PDP, it’s boxy. It’s also touted for toughness and practical features. In the eight months or so, as of this writing, that I’ve carried the Pro ACRO six days per week at work, I have found these claims to be true. It is not covered by the Dara brand Level 2 (excellent, by the way) holster I use. So it’s been the object of countless unintentional minor bumps and a few major ones as I’ve occasionally misjudged a doorway while carrying a heavy load.
The motion-activated ACRO has been superbly reliable; the plain red 3.5 MOA dot turning itself on to whatever my most recent brightness of choice was. Its 2032 battery has not yet needed replacement. When it’s time, that’ll be easy thanks to a “dime screwdriver”-accessible cover on the side. Brightness is simple to adjust with +/- buttons on the left side. On the rare occasion that I’m turning it off for more than a day, battery conservation is easily attained by holding down both of the brightness buttons for three seconds.
For all the praise I have for this setup, one thing I’ve learned is that the best optic product lines have the occasional, single sight with a big or small problem. And my particular ACRO has a small one. The dot was perfect from the factory in terms of elevation adjustment (a subjective ideal indeed; pick something and deal with it. Mine is 25 yards).
Windage Trouble
But windage is a slight problem; the sight has a dot that lingers, at maximum adjustment to the starboard side, just to the left of the center of the front sight post. Could I send it back for a warranty claim? Yes, but it’s good enough to pass the four torso shots at 25 yards that my state’s qualification requires. I’ll admit, making six-inch bullseye hits requires a right hold. Since I use the gun daily and its accuracy is better than passable, I’m ignoring the minor issue for now.
Its Ergos are Fire
Walther nailed it in the ergonomics department. Every PDP I’ve fired (Pro ACRO, steel frame comp, full-size base model, F Series) handles extremely well.
Early marketing materials for the line extolled the grip design that allegedly is optimized for electronic optics by encouraging a firmer pinky grip which has the effect of pulling the dot into view from 12 o’clock. Maybe pushback from shooters in the six o’clock camp dampened the focus on this claim. Regardless of the messaging, it just works, and I’ve found this is true for anyone else who handles my PDP. It’s been in the hands of new shooters and old pros of virtually every adult stature. They all like it and can shoot it well. This is in no small part due to the grip. Its deep tang and rubberized, pyramid-shaped dots all offer lots of control. Though the Pro ACRO is obviously lighter than the steel frame PDP, I find it tamer and easier to operate recoil-wise.
All of that grip commentary is from myself and others who’ve fired my Pro ACRO without the mag well. A commenter on my YouTube review disagreed with removing the mag well. He prefers the mag well for his bear paw-size hands because it helps keep his grip high and secure.
Reaching the PDP’s Controls
By now it probably goes without saying, but to be clear, this polymer-lower gun includes three backstrap choices. I’m not wild about the rolled aluminum pin that holds them on, but that’s a minor detail. Removing the backstrap reveals a slot for an RFID chip, a detail apparently included for agency use. I’m paranoid enough to have had my first PDP x-rayed to confirm there’s not a chip in there.
Likewise the controls are set up perfectly, in my opinion. Extended slide locks on both sides of the frame and a shielded, optionally ambi magazine release offer fingertip convenience for shooters of any size or hand preference. With its prominent slide serrations, racking is easy whether gripping the slide behind or in front of the ejection port. The setup has held up well to some students who grab the ACRO for racking (perfectly acceptable, just not my preference).
As with most handguns, I find it helpful to put more finger into a PDP trigger guard than just the center of the pad. It reduces any tendency to influence the muzzle laterally.
The PDP Pro’s Performance Trumps Sacred Cows
The gun carried to protect life must be utterly reliable. My PDPs have never malfunctioned with FMJ or JHP ammunition. The ACRO has never failed to turn on and be there as needed (this assumes my responsibility to present the gun at the beginning of every shift, confirm presence of the dot, and adjust brightness for the weather du jour). Too often, handguns are purchased by individuals and agencies based on some combination of popularity, effective marketing, and outmoded military testing standards. The PDP Pro ACRO has now been around long enough to have earned its way to respect among armed professionals and private owners alike.
Finding holsters for new-ish models can be challenging. There are plenty of non-duty PDP holsters out there, but finding Level 2 or 3 holsters can be a challenge. Dara Holsters is a solid choice. Mag carriers can be even tougher to find. Falco Holsters brand has worked well for me; though they didn’t have PDP-specific pouches they worked with me to find a compatible setup.
What Does the Walther PDP Pro Acro Cost?
At $1,599 MSRP or $999 officer/agency pricing, Walther priced the PDP Pro ACRO fairly, considering the valuables included like the direct-mount optic, tritium sights, and three magazines. It should be on the shopping list of anyone who’s ready to upgrade to a pistol that’s tough, trustworthy, and a pleasure to shoot.
