(I posted a similar thread about the Steyr GB a couple of days ago and at the suggestion of some of the members I'm posting similar threads about the P9S and P7)

When I first started shooting in the 1980's these were still near the height of their popularity but I had never seen one "in person" until this little beast showed up in the mail. The pistol, although 35 years old, looks almost brand-new--I was really pleased with its condition. I knew they were a little different than the typical mid-late 20th century but it wasn't until I had this one in my hands that found out really how different they really are.

I sold my first P9S (the one featured in most of the pictures), regretted it, and picked up this one a couple years later.

Overview
The P9S is a locked-breech, recoil-operated semi-auto pistol. It's 12.6 prohib with its four-inch barrel (although I believe there are non-prohib length barrels available, as well as the longer barreled "Sport/Target" (complete with adjustable sights and barrel weight) with model. Mine's a fixed-sighted "Combat" model, and there was another model with the Sport/Target model's sights and the shorter barrel mine has--it was known as the "Target" model. The pistol balances and points nicely, and has a nice low bore axis. The eight-round magazine is held in place with heel clip instead of the more common push-button release.

The side of the slide are semi-polished with a very attractive finish, while the top rounded portion of the slide has a duller finish.

The sights are large and easily visible, with the front having a white stripe and the rear having two red strips.

_MG_1312.jpg

There is a small notch in the slide that the cocking indicator protrudes through when the pistol is cocked.

_MG_1313.jpg


The slide itself is remarkably thin-walled compared to my other pistols--the roller-locking action means that the slide is not directly locking the pistol so it can be made thinner and lighter. I'm thinking that this might translate into lower felt recoil since there will be less reciprocating mass with a lighter slide.

_MG_1317.jpg


The frame of the pistol is actually two pieces--there's a steel "skeleton" that contains the bits and pieces of the lockwork, but, unexpectedly, the entire front face--trigger guard, the finger-grooved area at the front of the grip--is a large chunk of plastic screwed to the grip frame. The takedown lever is located at the front of the trigger guard--just push it up and the barrel slides off.

_MG_1320.jpg

Despite the pistol's appearance it's not striker-fired--there's a good old-fashioned hammer contained within the slide. I don't know for sure the design reason for this…I'm guessing it was to provide a snag-free exterior

_MG_1322.jpg

The grips are hard plastic with a thumb-rest on the left side--these would be awkward grips for a left-handed shooter. The pistol's grip is unexpectedly deep front-to-back; the single-stack magazine contributes to the feel. It certainly doesn't have the "moulded to my hand" feel that my 35years newer H&K P30L does!

With the roller-locked action the barrel does not tilt during the firing cycle so the recoil spring actually surrounds the barrel. The barrel itself is fairly substantial. You can see the recesses near the chamber that the rollers lock into.

Here's the bolt head removed from the slide.

and how the bolt head and barrel fit together.

Operation
The left side of the pistol grip behind the trigger guard resembles the decocking lever on SIG pistols--it's that and more! It can be used as a slide stop--push the lever up when retracting the slide to lock it back, push it partway down and the slide will be released. Surprisingly, if you start with an uncocked pistol and the lever is pressed all the way down, the pistol will be cocked! I don't know if this was intended as a combat feature or to enable easier single action practice. Lastly, the lever can be used to decock the pistol--but it's not as simple as with a SIG. You have to depress the lever all the way down, pull the trigger (!), release the lever, then release the trigger.

Another thing that surprised me was the operation of the safety. It looks just like any another slide-mounted safety that you's see on a Beretta or older S&W semi-auto. Up for fire, down for safe. But--the big difference is that it is not a decocker, in fact it doesn't affect the trigger at all--with the pistol "on safe" you can pull the trigger in double or single action and the hammer will still fall. the safety is just a firing pin lock. I can see how under stress if you forgot the pistol was on safe you could pull the trigger and not know it until you heard "click" instead of "bang". On the plus side, the pistol can be carried "cocked and locked".

_MG_13151.jpg

I was surprised how much the trigger action reminded me in many ways of my P30L, which has the V1 LEM trigger. The double-action pull on both is long (especially so on the P9S) and really stacks at the end. I know that on the P30L the DA pull is intended (I think) only to be used as a "second strike" option on a bad primer. I don't know what the design intent was for the P9S, but the DA pull is pretty rough. On the other hand--the single action pull is quite nice. Like the P30L's LEM trigger, there's a long, light take up (like a two-stage trigger) before you feel the final resistance.

Here's where the SA pull starts:

_MG_1338.jpg

Here's where the final resistance starts:

_MG_1339.jpg

and just past there is the sear release. (look how much overtravel these is, though!)

The final let off is wonderfully light and crisp, and the reset is super-short and positive. What I like about the P9S compared to the newest P30/HK45 generation pistols is that once you feel the "click" of the reset you're right back at the point of final resistance, whereas with the newer ones once you feel the reset click you have to pull the trigger rearwards a bit more before the final resistance. But--there's a downside. After the trigger releases there's a huge amount of overtravel (look at the picture above!). The Target and Sport/Target models had a trigger stop to minimize this but not the Combat model--the trigger needs to travel further rearward in DA mode.

During my first range trip a few years ago the P9S did not disappoint, though. As I was hoping, the lightweight slide made for pleasantly light felt recoil, and combined with the very light and super crisp trigger pull made for some very quick follow up shots. Unfortunately, all I had on hand was old surplus NATO spec 124 grain ammo so I was not expecting super accuracy but the pistol surprised me. Even though I had not been out shooting in two months I was pleased with how easy it was to shoot the pistol accurately.

Here it is in action last December:



I consider the P9S and P7 models the "classic" H&K pistols. Their newer models like the USP and P30, while excellent pistols, aren't as unique as the older models. With its curious features and requirement for complex manufacturing it was not destined to be a worldwide hit, but it's a great example of uniquely German handgun engineering.
 
Outstanding!

Great photos, both as to photo quality and what you choose to show and how you show it.

Thank you very much for your efforts!

That H&K looks great especially for being 35 years old, good find. It looks a lot like the Sig P232 or the P232 looks like the H&K P9S. (yes I know they are in different calibers.)

Another great review! Thanks again for the clear concise narrative and photos.
 
A club member here had a P9S .45 Target that was very accurate and easy to shoot.

I have not seen a .45 Sport with muzzle weight, but I always thought you could do interesting stuff with the 8" "Hunting" barrel.

Jeff Cooper quipped that H&K took the money they saved with steel stampings and plastic construction and plowed it back into the elaborate barrel extension and roller bolt.
 
Very nice photo essay. I'd just like to add a couple of clarifying points...I've owned both the .45ACP and the 9mm versions

I've always thought of it as a locked-breech action also, but technically is isn't.

It is a delayed blow-back, as the breech block starts unlocking, ramps in the extension camming the rollers inward, as soon as recoil starts. The pressure from the case head pressing against the breech face is what delays the free movement of the breech block.

An interesting thing about the action is that it is self regulating. The timing of releasing the breech block is dependent on the pressure of the load

The slide itself is remarkably thin-walled compared to my other pistols
The slide was an early example of a stamping with the front and end caps welded in after the sides were formed.

The 6 indentions in the slide, 3 on each side, form the whole of their slide rails

The pistol's grip is unexpectedly deep front-to-back
This has to do with the action being sized to function with the .45ACP and .38 Super cartridges

You have to depress the lever all the way down, pull the trigger (!), release the lever, then release the trigger.
I didn't find that this was true with either of my P9Ss.

When the lever is depressed all the way down, it releases the hammer, which is then lowered by easing up on the lever

One of the differences with the H&K thumb safety was that it was very easy to flip on and off. It wasn't spring loaded like that of the Beretta 92, but it wasn't a dead lever like that on the S&W Gen 1/2/3 semi-autos either.

It was fairly easy to push off if you chose to carry it in Condition 1 with the hammer cocked and locked. It was easy to modify for competition
 
Great review....thanks! I thought that the P9 or perhaps another H&K from that era was one of the original high capacity 9mms. Was there a higher capacity model?

You're thinking of the H&K VP-70

It was the first mass produced polymer pistol (introduced in 1970, beating Glock by 12 years), which had a magazine capacity of 18 rounds.

With it's stock attached, it was capable of 3-round burst and a cyclic rate of 2200/min

Thanks for the comments! That's unexpected that the decocker on yours was different—on both my previous and current one the hammer wouldn't decock unless the trigger was pulled while the lever was depressed.
 
I bought a VP-70Z, I soon realized I should have bought a P9S instead. The VP-70Z wasn't a bad gun at all, it fired everything I put in it, but that trigger was beyond weird, and well, it was really ugly. I came pretty close to break even on it and soon sold it. I replaced it with a Beretta 92, which I really liked.
 
Dragonfly:

A head's-up before you shoot again; the P9S...like the HK4, contains an "Elastic (Polymer) Buffer" (Part #12) which...with time ;), frequently hardens to such an extent that it yellows, shrinks and becomes very brittle. Failure...cracking/disintegrating, of the buffer can cause serious damage to the frame.

The buffer is held in place within the dustcover by the sheet metal "Buffer Housing" BTW.

Hope that helps :)

Excellent point—I should have mentioned this in my original post! Yeah, it'd be a hell of a shame to get one of these pistols then ruin it! Luckily the dealer I bought this one from replaced the buffer before I bought it—and I've got a spare I picked up from Numrich in case that one wears out.
 
Nice review, thank you for posting. My P9S is now retired, for me, it is the best shooting 9mm I've ever shot. I still haven't found a 9mm that fits my hand like the P9s.

Mine was one of five retired German police guns I purchased for $249 each back in the eighties.

Excellent DF, UR GTG then :D...just didn't want it to go unmentioned in such an otherwise excellent report ;):D.
