With Steyr M9-A1 for comparison. Both have factory 106mm barrels for import to Canada.
You are probably about to get a bunch of "do a search" comments from the regulars, but I don't mind this post. I always love to play the defender of my beloved P99 and P22.
I have a P99 AS in 9mm and I am almost completely satisified with it - and I am picky to say the least. For similar guns, I have a Glock 17 and a Steyr M9-A1 as well, both of which I have a few small reservations about (although both are definite keepers), but not so much with the P99. It's a solid piece of hardware. I'll post some pics of it this weekend when I get a chance.
On the positives: I would say accuracy is #1. Becasue it is SA/DA it is "cheating" a bit to compare it with DAO pistols on accuracy, but the fact remains that, in my experience, this gun easily outshoots a Glock or Glock-type gun. It should more properly be compared against SA/DA USP's and Sig's for it to be a fair competition. The "Quick Action" model is the one that should compete with the Glock. I believe the Montreal PD uses the P99 QA, as does the NRW Police in Germany (which is some kind of regional police force - North Rhine, Westphaelia - or something like that). Cop guns are almost always DAO, though.
At the range, I like using these paper targets that I just run off with a photocopier. Each 8 1/2 x 11 sheet has 2 big circles on it that are about 5 inches across. Each of the 5 inch circles has a 2 inch circle inside it. I'll set up 6 sheets of paper like this on "stand up" target about 10-15 yards back (depending on how well I'm doing that day

) at the outdoor range. So what you have is 3 rows of circles, 4 circles across on each row. With my Glock or Steyr I usually just try and get all 10 shots inside one of the 5 inch circles firing fast, or maybe double-taps or some other game. With the Walther P99 I generally have no problem putting my first shot inside the 2 inch circle, and can just work my way across the target rows: one shot on each circle...across the row... 1, 2, 3, 4... all inside the 2 inch circle, ...next row, same thing. On all 12 tagets, I might miss the 2 circles once or twice. If I try this same game with my Glock or Steyr I will hit outside the 2 inch circles at least 60% of the time, and outside the 5 inch circle on some of the shots.
My point is, the P99, at least the DA/SA version, is in a whole different category for accuracy than many of the guns it is compared to. Alot of my example, I'm sure, has to do with my own shooting style than the gun (I believe the Steyr would produce the smallest group in a controlled bench-rest type experiment), but I'm just saying... the P99 is a real nice piece of kit that doesn't take a backseat to any other pistol.
Some other things I like about it:
The grip is very comfortable. Walther has come closest to my idea of an optimal ergonomic grip.
The interchangable front sites are a cool idea that works great and will save you time and money with the gunsmith.
It has both a cocking indicator (which is only really necessary because it is a striker fired, not hammer fired, SA/DA) and a loaded chamber indicator. It also has that de-cocker which is cool and useful (in
Casino Royale... when Bond does his "click, klak, slap, bang" function check on his P99 in the car, notice that he pushes the decocker at the end of it all

). If we lived in a carry jurisdiction you could carry it around with a round in the chamber and a long heavy DA pull, but if you move the slide back half an inch or so it will switch to SA without disturbing the round in the chamber, and if your "condition red" emergency situation ceases, just hit that decocker button and you are back to heavy-pull safe mode. Also unlike a Glock-type gun, if the first hit from the striker fails, you can keep pulling the trigger in DA mode and the striker will keep hitting the round - and hopefully firing it. I always thought that was a weakness of some of the DAO pistols. Once you pull that trigger, if the round doesn't go off, the action is dead until you manually pull the slide back, and in an emergency situation that may not be easy - or even possible. SA/DA seems like a great thing for life-and-death situations (assuming that the damn round will fire at some point if you hit it enough times!). All of this stuff is common to Sigs and USP's and Beretta's and other SA/DA guns, but is unusual for a striker fired polymer gun.
The insides of the frame are very wide open and it is easy to clean everything without taking it apart (beyond field stripping). On the downside, these same insides seem to dirty up more than other guns (like a Steyr M9-A1, or even a Glock) where the "guts" of the gun are relatively shielded from the gunpowder residue. I do not believe - and have had no reason to believe in my use of my P99 - that there is anything "weak" about the guts of this gun, as some people seem to think. It is just somewhat unusual that you can see so much of the trigger mechanism when you take the slide off.
On the down side:
The striker-fired SA/DA trigger is a little different from most hammer-fired SA/DAs. In single action mode, the trigger doesn't move back by itself. When you go to SA mode, the trigger starts from the DA postion but then travels back to the SA position (by the push of your finger) with almost no resistance. I find that when you are shooting, you don't really notice this very much, but when you are playing around with it in your hand - with snap caps or whatever, it seems kind of weird. I think I would prefer it to be like the (hammer-fired) P22 and other hammer-fired SA/DAs and the trigger move back by itself.
Yes, the grip does look more "plasticy" than other polymer guns. This has more to do with the texture of the finish than anything else, but it is not the pistols finest feature.
The P99/USP style mag release is not everyone's cup of tea. I guess this is how the German police and military want it

confused

. It seems like no one else does it that way and, I don't think the mag can really be released without loosening your grip and shifting your hand somewhat.
The rails seem to be very small. This doesn't seem to have had any effect on my gun, but I like the look of very robust rails - like on a Steyr (which I use again as an example becuase i know it well). Psychologically it is appealling to me to have big burly-looking rails.
Over all, this is an incredibly cool gun that is unique and is just pure quality and engineering all the way through. Walther hasn't been around this long without learning a few things about how to make a gun. I do agree that it is a little overpriced though. Here in Vancouver, they usually go for $1,199 - which is $200 to $300 more than what I think it should be.
The P99, along with the P22, is one of my favorite guns of all-time. It's not everything to all people but, for what it is, it is a very, very good pistol.
