Split trigger and what weight recoil spring...early models had springs set for 124 gr as per Europe, later models had lighter springs set for 115 gr USA market. Different serrations on the slide....Other than the trigger "ramp", what does the year matter on the P99?
Hmmm, I was not aware that they changed recoil springs to accomodate 115 gr. bullets.Split trigger and what weight recoil spring...early models had springs set for 124 gr as per Europe, later models had lighter springs set for 115 gr USA market. Different serrations on the slide....![]()
I was having some trouble during the break-in period (500rds) with my 1998 AS. Probably just didn't give it enough time but I was having trouble with it cycling my reloads. Called WalterAmerica and tech told me about different spring. You will also find this info on Dr. Lunde's FAQ...Hmmm, I was not aware that they changed recoil springs to accomodate 115 gr. bullets
Do all P99s share the same recoil spring?
Yes. However, there is a reduced recoil spring available from Walther for use with Suppressors and with 115gr bullets during break-in. The standard recoil spring is rated at 50 Newtons or 11.24lbs, and is silver in color; the reduced recoil spring is rated at 48 Newtons or 10.79lbs, and is red in color.
The only other recoil spring made by Walther for the P99 is meant for the new S&W SW99 chambered in .45 Auto, but it would become completely compressed before the slide goes back far enough if used in a 9mm or .40 Auto P99

I can't tell you for 100% sure but from what I got from a WaltherAmerica tech, this took place when S&W became the primary importers of Walthers. These pistols were geared specifically for the US market. We over here prefer 115gr...many in Europe use 124gr. This is the reason for the switch, so I was told.In a previous post you stated that Walther went from a recoil spring that was designed for 124 gr. to one designed for 115 gr. When did that happen?
