Walther’s Modern 9mm Handguns

Walther has a long and interesting history in manufacturing quality firearms. An innovator in double action first shot firearms with the tremendously influential P 38 today Walther manufactures top quality striker-fired polymer frame handguns. Walther firearms are reliable, that is the baseline, but also feature a superior trigger to most modern striker fired handguns. I currently own and use two Walther handguns on a regular basis. My favorites among the Walther types are the Q5 Match and the PDP 5 inch barrel version.

Q5 Match

The Q5 Match is a match winning pistol in some forms of competition but also useful as a carry gun. It isn’t small but it is light and handles extremely well.  This pistol provides a heft and balance that makes for easy shooting. While it may be used in quite a few types of competition, I find the pistol to be an ideal personal defense tool as well. A handgun that handles this quickly, is completely reliable, and more accurate than most, is clearly a good defensive handgun. Hand fit is extraordinary in most ways and recoil pleasant even for a 9mm handgun. This handgun is based on the proven PPQ handgun. There are certain improvements in sight radius. The trigger action of the Q5 is superb. The hand and grip interface is good for most hand sizes. The pistol is optics ready and features a modern frame rail. A modern light rail is part of the package.

The slide features 16 weight-saving cuts. While the balance of a long slide pistol is maintained this expedient lightens the slide. The slide is black Tenifer while the frame is molded black. The trigger is a bright blue. A high visibility fiber optic front sight compliments the fully adjustable rear sight. For my tastes I added a Vortex Viper red dot sight. My first quality pistol mounted optic was a Vortex Viper and I continue to count the Viper as a trusted carry optic. This sight allows real speed with the Walther 9mm handgun.

Please be certain to order and optics ready holster when choosing the Viper red dot sight. The Q5 uses PPQ and PDP 15 round magazines.  Walther’s  Quick Defense trigger is crisp and sharp- quite different in feel from the Glock and most striker fired trigger actions. A blade type safety lever is set into the trigger action. Take up is less than one half inch. Reset is sharp and rapid.  The trigger action originally broke at just under five pounds. After years of use the trigger now registers 4.7 pounds on a trigger compression gauge. That is a good break in.

The PDP

I have enjoyed good results with the PDP in several variations including the PDP F with it’s smaller grip frame. The pistol illustrated is the five inch barrel version. This compares nicely to the Q5 in balance and feel. I will cut to the chase- the PDP has proven as reliable as any handgun and equals or exceeds the Q5 in most areas.

You may change out either pistol’s grip straps for better hand fit. The magazines interchange, the PDP features a compact version in the line up. The PDP has a wider slide with Super Terrain cocking serrations. The grip is superior to the Q5 although certain shooters may not agree, it fits my hands better. The trigger action on the PDP is almost as good as the Q5- it takes a good shot to perceive the difference. Lets look at specifications for the Walther PDP and get to the firing tests.

 The PDP is wider but lighter than the Q5. The Q5 is being phased out of Walther production from what I understand.  I will be perfectly happy to purchase a new PDP if I ever need another Walther. The PDP is offered in a seldom seen Match version.

So how do they shoot? First I added a Holosun 507 to the Walther PDP for sighting. Widely available, durable, and useful, this sight offers good service at a fair price. I collected a number of loads from Black Hills Ammunition. This removed all doubt as to ammunition quality. Here are my results from a solid bench rest firing position at a long 25 yards.

The difference in performance is slight- almost insignificant. Carrying the pistols wasn’t difficult. I know a maker that supplies some of the best holsters on the planet! The Falco holster A911 Talonguard is a hybrid holster that allows carrying not only an optics ready handgun but a handgun with a combat light. This is a Hybrid holster that is very well put together. This construction of leather and Kydex makes perfect sense although it isn’t simple to get the materials to come together correctly. Falco got it right. I mounted a Streamlight TRL8 light on the Walther Q5 and slipped it into the Talonguard holster. A strong steel belt clip holds the holster secure to the gun belt. The draw is sharp. If not properly designed a light bearing holster will allow the flashlight to drag. Not with this holster. The draw is sharp and the reverse presentation or re-holstering the handgun is smooth. I like this holster very much.


PDP and leather

Falco offers good quality leather holsters for the PDP. However, I did not have one on hand when I first obtained the PDP five inch. I remembered my first Falco holster. Many years ago I obtained a simple Nylon holster with a steel belt clip. I have never worn it out although the finish has worn on the steel belt clip. This holster is about twelve to fourteen years old and still useful. I sometimes carry the standard compact PDP in this holster. I used a modern Airflow light bearing/optics ready holster with the PDP. This is a good set up. Comfortable, affordable with a strong belt clip, the Airflow works well. Plus, it offers a sharp draw. If you need an affordable holster that fits more than one handgun the Airflow is a great choice.

FAQ About the Walther PDP and Q5 Match

The Walther PDP and Q5 Match are both striker-fired 9mm pistols known for excellent triggers, ergonomics, and accuracy, but they have different design priorities. The Q5 Match was developed with competition shooting strongly in mind, while the PDP is a newer, more versatile platform designed for duty, defensive, range, and competition use. In our comparison of the 5-inch models, the PDP is slightly wider but lighter, while the Q5 Match has a slimmer slide and a particularly refined Quick Defense trigger.
The Walther PDP equals or exceeds the Q5 Match in several areas, although choosing between them depends on personal preference. The PDP offers excellent ergonomics, aggressive SuperTerrain slide serrations, an optics-ready design, and a very good factory trigger. The Q5 Match still stands out for its balance, accuracy, and exceptionally crisp trigger. During our testing, the difference in practical accuracy between the two pistols was relatively small.
The Walther PDP 5-inch delivered excellent accuracy during our 25-yard bench-rest testing. Using Black Hills Ammunition, five-shot groups ranged from approximately 2.1 to 2.9 inches depending on the load. The best result came with 124-grain JHP+P ammunition, producing a 2.1-inch five-shot group.
The Walther Q5 Match proved highly accurate during our 25-yard testing. Five-shot groups ranged from approximately 1.8 to 2.7 inches with the tested Black Hills Ammunition loads. The best result was a 1.8-inch group with 124-grain JHP ammunition, giving the Q5 Match a slight accuracy advantage over the PDP in this particular test.
Yes, both the Walther PDP and Q5 Match are available with optics-ready slides. In this review, the Q5 Match was equipped with a Vortex Viper red dot, while the PDP 5-inch was tested with a Holosun 507. When selecting a holster for either pistol, make sure it is designed to accommodate the specific red-dot optic installed on the handgun.
Both pistols have excellent striker-fired triggers, but the Q5 Match has a slight advantage in our experience. Its Quick Defense trigger has a crisp break, short take-up, and positive reset. The PDP trigger comes very close, however, and the difference may be difficult for many shooters to notice during normal range use.
