Just bought my P99 and on my first day at the range I had a problem with one or 2 rounds a magazine seeming to enter the chamber pointing upward too high and then jamming and not seating completely in the chamber. I fired 70 rounds and every magazine but the last one had this happen at least once. On my second day of firing after taking my P99 home and cleaning it and not using as much oil as before the first magazine had 2 rounds not seat and the 2nd magazine did the same thing but then 7 magazines fired perfect. I am hoping that it was just a break in period because the Pistol was brand new. I used Winchester ammo and range reloads.
*Any other Members have this same problem at first and do you think it was just a break in period?

Ummm....... more info please.
Is it a 9mm or .40?
If its a .40, what color are your magazine followers?
If a 9mm, try using 124gr. or 147gr. ammo for the first 200 or 300 rounds.
The Winchester white box ammo (especially the 115gr. FMJ Wal-Mart ammo) is notoriously underpowered, and range reloads always are a bad idea in my experience.
I've had great luck with CCI Blazer.
I broke in my P99 9mm at a OPS Tactical Pistol course, which was around 700-800 rounds in 2 days. I had zero malfunctions.
I used Winchester 124gr. FMJ ammo for the entire course.
Over tha last year or so, i've shot well over 6000 rounds thru my P99 with zero malfunctions. My ammo has ranged from, Winchester Wal-Mart Value Packs, Norma mil-surp, CCI Blazer, Speer GD +p, Winchester and Federal HP's, Remington UMC, and a few other quality 9mm's.
My advice is buy some good quality ammo, that has some"punch" to it, and break your P99 in with that, then you should be able to shoot anything you want.

About a month ago, a friend of mine purchased a P99 QA in 9mm and had quite a few jams / failures to feed his first night on the range.  His issue was that the recoil spring was breaking in.  This was exacerbated by the fact that although he was firing good ammo, it was light ammo (Fiocchi 115 gr).  -At this point, he has roughly 300 rounds through it and no jamming problems.  It's a tack driver.

-For what it's worth, I think it takes about 500 rounds through a gun for it to "find itself."  It's a break-in period where the parts get to smooth out the sharp edges as they wear against other parts.  Typically, I won't start messing with a gun or its sights until I'm past the 500 round mark.  After that point, I have confidence I know where the gun is going and most perceived problems have evaporated either because the gun has broken in or I have acclimated to the gun.

Thanks for the info. I should have mentioned that my P99 is a 40 cal and I was using the white box Winchester target ammo 180 grain and range reloads. My son uses CCI Blazer with his Glock G22 an has never had a jam. I should try those next. It seemed like the P99 was breaking in because the last 7 magazines fired perfect and that Green and Black P99 captured all the attention at the range I train at (where there were some impressive 1911s, Berettas and Glocks shooting also) I let 2 guys I knew and trusted fire it and they really thought it was cool. I would not be alarmed about my P99 but none of my weapons when I was in the Army ever jammed and my little Beretta Tomcat also never jammed. When I bought my Walther I was happy as h*ll because I felt like I finally had one of the best if not the best. My hope is that it was just a breaking in period and my P99 will in fact be what I think it should be.

(it sure look great in DIE ANOTHER DAY)

What color are the magazine followers in your P99 .40?
There a orange and blue followers, the blue magazine followers are the new improved versions.

 

[raven82]

They are Blue. My Pistol was test fired on 02-01-02. That was the date on that little envelope with the spent casing inside.

I also failed to say that I LOVE this Pistol and wanted a Walther way back in 1973 when I saw the old PP and PPK models advertised. Finally got my son through college and got a divorce so I was able to buy what I want for a change.

Thats funny because I just my .40 p99 and fired 200 rounds through it without a single problem. Well, unless you count my horid accuracy issues against the gun. I was using range reloads, 9.99 per 50.

My P99 .40 has done great with "Winchester", and "UMC" ammo, but it doesn't like "Sellier & Bellot" at all, the round will go halfway into battery, or the slide will be 1/8" from a full return. I'm going to try some good defense ammo through it, just to make sure it digests it, so I can trust it.

Sound like Raven got himself a partial S&W P99. I would be willing to bet it does NOT have German proof marks on the slide and barrel. There are MANY P99s in 40 military , out there like the above mentioned. That could explain the malfunctions.

I have a new SWalther P99, ran 200 rounds if Win White with no problems. Only thing I do not like is groupings at 50 feet...it is dead accurate at 20 feet! Anyone else's gun have this problem?

 

[raven82]

Allglock and Members,
After really reading up on Walther and their recent merger with S&W I am certain I have a Walther that is made in Germany and Maine, USA. After about 100 rounds it is now firing perfect. I was told that it may need a break in period and because it is built so tight it has little slop room like my old 1911 I used in the Army that rattled like crazy.
I use my P99 now as my service pistol and I know it will not let me down. I now have as much faith in my Walther 40 cal as I do in the Pistol I call "Little Trusty" my Beretta 32 cal. TomCat.
My close range Pistol and my back up to my P99.

 

[allglock]

Raven, check your slide and barrell for GERMAN proof marks, and get back to us.

 

[raven82]

AllGlock,
My P99 does not have that German insignia on the back of the slide. On the right front of the slide it sais.
Walther USA LLC
Springfield, Ma
On the left front of the slide it is inscribed in gold Walther P99. (in is not stamp engraved like some P99s I have seen)

The lower polymer part of the pistol has
Made in Germany
and some German and English safety warnings

I have a SWalther P99 40. I experienced grouping problems and a very severe case of low shots (I don't know the technical term). The shots were sometimes so low that the gun was unsightable. Until....around 1500 shots the gun suddenly started shooting at point of aim. I'm talking that within 3 boxes the problem solved itself. Being a beginner, I'm totally confused as to why this would happen. Any insight would be appreciated.
