Kind of a follow up to my previous post about the usability of a 9mm slide and barrel on a .40 frame...will an SW99 slide and barrel assembly function properly on a P99 frame? I know they’re nearly identical firearms but I’ve never been able to determine compatibility of something like this.

I seem to recall someone switching a PPQ slide with a P99.
I would venture to guess that the slides for the PPQ, P99, MR9 are interchangeably.
The frames were made by Walther, while the uppers were made by each respective manufacturer.

On a further note, the P99 & MR9 have a fantastic trigger, while the SW99, not so much. The SW99 lacks the short reset found on the other variants.

Without having them in front of me to try out myself, I'll say that they should. Walther made all of the frames for all of the 99-series variants from all licensed copies. I doubt they would change the design of the frame for another manufacturer.

The reset on these pistols is determined by a tab on the trigger bar that slides forward of a tab on the single action lever, which are both in the frame. The design should be nearly identical, and the reset should be nearly identical on all variants. Walther made the frames and the frame internals for all variants for all of the licensed copies.

I stand corrected. I just had my SW99 out, and you are correct; the reset is the same.
I must of confused it with another variant.
Now I’m going to have to go through the compacts (P99c & SW99c). To find the one with the odd trigger reset. Unless I’m having a senior moment, and misremembering.
