Walther PPQ 45 M2 .45 Suppressed

The Walther PPQ was the first handgun I found that stood a chance at unseating the Glock 19 that I’d carried for years. This was a 9mm PPQ M2, not the PPQ 45 here in this review, but the ergonomics of these guns and their performance are both very similar. The gun fits my hand, points exceptionally well, and provides the solid reliability that we should all demand of our EDC guns.

And now, years later, I’m looking at the gun for a different reason: sound suppression. I recently picked up a Banish 45 and had been running it on a couple of 9mm handguns, but hadn’t had a .45 ACP with a threaded barrel. The PPQ 45 doesn’t come with a threaded barrel (at least this one didn’t), but Walther makes a threaded barrel for it, and the combination is ideal.

There is a catalog model (The PPQ 45 SD) that comes with the threaded barrel, if you’re lucky enough to find one in stock.

The Walther PPQ is known for its exceptional ergonomics and its short trigger reset.

The highlight of the PPQ line is a toss-up. The trigger is truly one of the best factory triggers available. The shoe moves less than half an inch. The reset is even shorter—just one-tenth of an inch. And there’s not a hint of grit or sponge in it. If trigger performance is important to you, this line has to be on your radar.

Walther PPQ 45 slide drop lever
The slide drop lever allows for a lot of actual leverage. This is one of the easiest slide drops in production today.

The remainder of the controls, though, stand out, too. And these are built into an ergonomic design that has come to define the Walthers of late. These guns have a complex geometry that matches that of the hand.

Walther PPQ 45 grip
Walther’s grip squiggles compliment the well-defined swells on the grip and make this exceptionally comfortable to shoot.

Check the image above. There are curves within the curves. The PPQ 45 has to accommodate a double-stack magazine, but the grip is still easier to hold than that of a 1911.

The rear of the frame is undercut for a high grip. This is one of the reasons why the gun points so well for so many. The trigger guard is undercut, too.

The grip is covered in small half-moon-shaped protrusions at alternating intervals. As grips go, this is not as tactile as some of the rough sandpaper-like textures that are growing in popularity, but still sticky enough that your hand stays where you put it.

Walther PPQ 45 slide serrations with banner
The front slide serrations are interrupted by the Walther banner but are still tactile enough to be useful.

The slide, too, has a variety of textures for easy manipulation. The cuts are deep and wide, and they’re not sharp-edged, but the depth alone is enough to provide for a solid grip. And the PPQ 45 has cuts on the front and the rear.

Walther PPQ 45 rail
The Walther PPQ has three slots of rail up front on the frame for attaching lights or lasers.

For those who run lights on their pistols (and everyone should run lights on their pistols), there are three rail slots ahead of the trigger guard. At over seven inches, the PPQ 45 is ideally suited for a full-sized light.

Walther PPQ 45
The controls are ambidextrous. The mag release, though, will need to be swapped to the right side for lefties.

The controls are worth talking about, too. The most noticeable will be the slide-drop lever. This is a long bar that protrudes from both sides of the pistol. While most guns offer a little nubbin of steel to thumb down the slide, this one extends far down the frame and requires very little pressure to actuate—that’s physics for you.

Walther PPQ 45 slide ribs
The slide has ribs down the top that interrupt glare.

There aren’t any external safeties, other than the lever in the trigger shoe. Inside, there’s a firing pin safety and a disconnector safety. The combination gives the PPQ M2 its drop-safe clearance.

Walther PPQ 45, suppressed
As the threaded barrel is an add-on for the PPQ, the sights are not built especially tall. They are still usable.

Sights on the standard version are a simple three-dot pattern. They’re low and unobtrusive. There’s a version that comes with XS night sights, and those seem like they may be taller.

In the stock configuration, the sights don’t clear a suppressor. This isn’t always bad, though you will need to know what your target looks like with the obstruction of the can itself superimposed between the front sight and the target. In other words, you have to make some allowances when using these sights with a can, but accuracy is still very reliable.

Walther PPQ 45 front sight
The front sight isn’t as easily seen with a suppressor on, but it is still functional. Though some of the target will be obscured by the width of the Banish 45, which isn’t overly wide, the three-dot set-up on the PPQ will still get allow for precise shot placement.

Shooting the PPQ 45

steel target
Running fast on steel, I found I walked up. The fifth shot was high—almost off the plate.

Almost all of the .45 ACP I’ve shot, more than 99% of it, is through a 1911. I’m a sucker for the classics. If my gun is going to be made of plastic, I’d rather have it chambered in 9mm. So this is a crossover of sorts.

But it could change my mind. The 12 round magazine and compact design make this a compelling choice for EDC, especially in winter when I could wear it OWB and still keep it completely covered. And everything about this gun is designed for regular use and carry.

PPQ 45 trigger
The PPQ has a superb trigger. The break is light, the pull is consistent, and the reset is minuscule: .1″.

I’ve already talked about the insane reset. One-tenth of an inch. This makes follow-up shots crazy easy. When combined with the PPQ M2’s ergonomics, which go a long way in mitigating the recoil and muzzle-rise of the compact .45 ACP, this becomes a seriously fast gun that is easy to keep on target.

In fact, if you are shooting one for the first time, the trigger will likely be the takeaway. It will take a bit of practice to get used to. The image below shows what I mean.

I was working on connecting up a group of shots and didn’t yet have my sights perfectly realigned when I pulled off that flyer. I’m accustomed to triggers that are a bit more forgiving, so I’d already begun to pull back in anticipation of the shot I was about to take when I felt the shot fire.

Did I mention the trigger break? The shot on the right surprised me.

PPQ 45 M2 Magazines

Walther PPQ 45 magazine
The magazine for the .45 is big and made of stamped steel. Like the other PPQ mags, it functions flawlessly.

With a 12+1 capacity, the PPQ 45 M2 has a solid capacity for a .45. The mags are built of steel and are stamped with several geometric impressions that both provide strength and guide the double-stack of rounds into a single column.

PPQ 45 mag witness holes
Witness holes allow for decent round counts without letting in too much debris.

The design works and doesn’t need to be babied. The most care one of these mags needs is a good cleaning and light oiling. As the bluing wears, watch for rust. Even then, though, buff it off and oil again and keep going.

mag catch
The mag catch reflects the ambidextrous nature of the gun.

The body of the mag is labeled with a caliber. This, though, is small. While the size is indicative of its caliber, the mag can get easily confused with others that look similar.

Walther PPQ 45 mag follower
The follower is plastic and sits atop a solid spring. Topping off the mag requires some thumb strength.

This is one of the problems with guns like this, I think. The mags are solid, durable—everything you’d want, really. They’re also not super easy to find. These are running about $40 a piece.

Walther PPQ branded base plate
The mags have branded base plates, which will help if you have multiple handguns, though the caliber is not marked, so you may struggle with identification if you have more than one PPQ.

Shooting the PPQ 45 M2 Suppressed

Walther PPQ 45 with a suppressor
The balance of a suppressed pistol changes, as does the recoil.

Adding a silencer can change your point of impact a bit. The shift isn’t much, but you may need to compensate for surgical shot placement.

A red dot can help with this, as the optic can be sighted in on the true point of impact. Some sights can be adjusted, too, which is a longer-term solution. So long as the silencer tightens down on the barrel in the same position (with the baffles in the same position, really), then the impact shift should be consistent with any given type of ammo.

The recoil is less of a snap up and more of a wave motion. There is still muzzle-flip, but it is not as steep when suppressed.

The Walther PPQ 45 M2 tends to follow a swimming motion during recoil. This is the part of writing that is complicated; I know exactly what I mean, but it is hard to communicate. The gun moves up (less than with unsuppressed fire), but there’s more mass, too, which slows that motion.

Then getting back on target requires that the downward momentum of that extra mass be slowed down so you don’t over correct and dip the muzzle down. This isn’t easy, so there is often a up, down, back up slightly motion that feels like the motion of a wave.

Banish 45 suppressor on Walther PPQ 45
The Banish 45 can mount via direct-thread adapter or like this, with a piston.

The Banish 45 is all titanium, so it isn’t heavy. And the baffles cut the sound of the .45 ACP to hearing safe levels. It is a joy to shoot, really, and the sound of those fat rounds thwacking on the steel is much louder than the muzzle blast itself.

.45 ACP cartridge
.45 ACP ball can be lethargic. The good news, though, is that lethargy means they’re subsonic. That makes them hearing safe from the Banish 45.

Holstering, though, is problematic. While there are plenty of holsters for the PPQ 45 M2, adding the threaded barrel makes it slightly harder to holster, and the suppressor is really more of a dedicated addition to the gun. For a home-defense gun, though, it is a solid addition. For range work or plinking, this is addictive. The PPQ 45 cycles everything, even when suppressed, and offers more on tap than your bog-standard single-action.

Price? Looks like the selling price would be somewhere on the positive side of $700, but that would be determined greatly by availability (they’re hard to find in the wild).
