I bought a Walther P99 in Feb, orignially as a present for a buddy. But after a range session, I decided to buy him a 4" Smith .357 and keep the P99 myself.
I have fired over 1000 rounds through the gun now, and have a pretty good idea of its reliability.
1. Size and Weight: It is a compact, lightweight pistol that conceals very easily. You can carry it all day and hardly know it is there. I carry it as a backup to a Beretta 92 or a Les Baer 1911 sometimes, and this is perfectly comfortable for me. Even when driving long distances.
2. Grip and Feel: The grips are adjustable on the P99, supposedly to make it fit lots of different sized hands. I use the smallest grip panel because I want the better control that comes from the smaller grip, even though I have large hands. The grip feels good and does a good job of protecting the shooter from being bitten by the slide, no matter how agressively they grip the gun.
3. Trigger: The trigger setup looks complicated on paper, but spending 10 seconds with it will make you realize that it is exactly like a traditional DA/SA auto. The DA trigger is decent, with a tendancy to stack near the very end of the pull. The SA trigger is light, but has the same tendancy to stack, though not as noticable as the DA trigger. The pull is still much better than a Glock's pull, but not quite as good as the XD's pull.
I have only used the decocking button on the range, as I carry the pistol in the "cocked" condition all the time. There are several internal safeties in the gun so this can be done in perfect safety.
4. Sights: The sights are decent ones that line up quite well at speed. My gun's sights shot a tad high, but there are extra front sights included with the gun to adjust for this. Rear is adjustable for windage. Both sights appear quite sturdy and have not budged, even survivng the drop tests. (later...)
5. Accuracy: Accuracy improved with the pistol as it broke in because the trigger pull got better. The P99 shoots very well. Slow aimed fire is able to produce shots that touch each other. At the range the other night, I used the p99 to cut a 3" hole out of the center mass of the target I was using. Shooting 3" dots could be done quite easily from the draw at up to 15 yards. After that more precise aim was required on the black 3" circles. 8" circles were not a problem even out to 25 yards.
6. Speed: The P99 is a lightweight polymer gun, meaning it has more muzzle flip than something like a Beretta 92. But with proper grip and stance, this can be mitigated and I was able to fire multiple shots/multiple targets without "feeling" any slower than I was with the 92. A PACT timer would have probably shown a difference, but it was not noticable.
7. Safety: After doing drop tests and throw tests on concrete flooring, the P99 had no failures. Dropped on the muzzle or on the back of the gun, the primer was not dimpled. A NOOB shooter I was training dropped the pistol while it was loaded on the range, and it did not fire. I was mighty glad I did them drop tests then buddy...
8. Reliability: The gun did not jam of its own accord, even with dirty magazines and no cleaning. 5 bucks to the person who guesses how I did get it to jam:
That's right! Limp wristing. I did my famous 2 finger limp wrist test, and the gun DID manage to jam, but not from stovepipes. The only thing it would do is cram the nose of a round into the top of the chamber and stick there. This required dropping the mag and racking the slide to clear. A simple Tap Rack Bang would have resulted in a nasty jam indeed.
I hasten to point out that I fired over 100 rounds with just two fingers holding the gun (the thumb and trigger finger) and it only jammed 2 times. This is not a suprise, as compact polymer 9mm's seem especially prone to limp-wristing problems when using ball ammo. I could not make it jam with +P ammo. (I could barely hold on to the thing with 2 fingers using +P as well...) Just 2 jams out of 100 attempts while doing something that NOBODY would ever do in a firefight is pretty good performance.
I could not make a jam happen with all fingers on the grip, no matter how loosely I held the gun. I figured that after the 3 or 400 rounds I shot that day (with almost no lube) that the gun would choke, but it did not.
Gripes:
As well as the P99 performed, I do have a couple of gripes:
1. Mag follower: The mag follower for the P99 mags is just a tiny, thin piece of plastic. It appears to work, but it sucks to know that I am depending on THAT puny thing. I would love to know if there were improved followers out there for these mags. Also my mags only seem to hold 15 rounds, when they are supposed to hold 16. These appear to be Turkish contract mags, so I am not sure if they were designed to take a round less...Herr Walther, any ideas on this?
2. Grip surface: It is a little too slick if you ask me. I would prefer something more agressive, or maybe a coating of a squishier rubber on the grip to give it more bite and reduce muzzle flip.
3. Rail system: You can't put an M3 or it, or any of the other standard lights. What gives here Walther? Can't join the rest of the 21st century? Proprietary light setups SUCK. Make it so I can put my M3 on there.
4. Trigger guard: They made a nice big trigger guard on the gun, and then flubbed it up by putting this stupid hump halfway through the thing. When wearing thick gloves you can pull the trigger 1/2 way just fine, then you bind up on that hump. A dremmel tool could probably fix this.
Overall it is a very good handgun for anyone who wants a compact 9mm to carry. It is accurate enough to hit soda bottles at 100 yards. It is reliable even when dirty and hot, and even when fanning the trigger to achieve a rate of fire that is just totally impractical.
The gun points very well, speeding up target acquisition. It handles all the ammo I fed it superbly.
On a scale of 1 to 10, 10 being the ultimate blaster that never fails and hits 1" circles at 50 yards no matter how badly you abuse it, the Walther is a solid 7.5. This is a very good score considering that nobody makes a 10 or a 9, and the best custom guns can only be about an 8.5 in my opinion.
I would reccomend the P99 to anyone who is looking at a compact polymer pistol. The fit and finish is superb, the lockup is rock solid, the accuracy and reliability are impressive, and the whole package comes in at just about 25 bucks more than a Glock. (Glocks sold for 495 at my old store. This Walther sold for 520.)
A bargain in my book...
