SW99C

I had to replace the recoil spring and guide rod on my SW99, could not get it from S&W, had to order from Walther.
I also own a full-size SW9940 and a compact SW999c. I ordered them as I was taking armorer classes for the 99 series over time (3 of them? I'd have to look), and I was also carrying an issued SW9940 for a few years.
Anyway, when I learned S&W had closed down their Walther America business at the conclusion of their Strategic Alliance agreement with Walther, I called to order some extra parts to fill out my armorer kit. I was told that S&W was in the process of trying to convince their existing SW99 customer agencies to adopt M&P's, and were also in the process of sending all of their Walther 99 parts (and magazines) to the new Walther import company being set up in the US.
Since S&W received all of their SW99, SW99NJ & SW990L parts - (except for the slides and barrels they machined themselves, for their licensed models) - from Carl Walther Germany, I imagine at some point down the road I may have to order some of the springs from the new Walther company.
Now, there have been some revisions and improvements to the 99 series as time has passed, so the older P99's & SW99/990L's use older versions of some assemblies, like the sear housing block.
Even when the SW99/990L's were still in production, Walther quietly changed an inside frame dimension which also required a change in the sear housing block dimension, so not all sear housing blocks will fit in all frames. It depends on the model and the production vintage. It was a subtle change, and not quickly visible to the eye unless you knew what you were looking at.
Here's a pic of 3 sear housing blocks of 2 vintages, with the 2 blocks on the right showing the difference in a "tube" pin change needed to make the new block fit in an older frame. It was a head scratcher for me until I called the factory and spoke to someone, and they explained the change and what I needed to do to get the right length pin in the new block.
Also, Walther engineers changed the trigger bar guide design in newer 99's and PPQ's, going from the original small steel "post" guide design to an adjustable lever design. This required a change in the shape of the sear housing block and the frame, and the different sear blocks are not interchangeable between the frames.
This pic shows the trigger bar guide posts circled in red. I don't have any blocks (or pics) that use the newer adjustable lever design (since my guns don't use that newer design), but the lever is located on the outside of the right side of the block, and it's screw adjustable. This adjustment ability is necessary in the Anti-Stress model guns (think DA/SA) so the safety block & striker firing pin "timing" between DA and SA trigger modes don't interfere with each other. This was originally achieved by the right length (height) steel guide post being used in the bottom of the block. If I remember right, a S&W tech told me they used 1 post in their standard 99's (think Walther AS model) and another post in their 990L's (think Walther QA model), due to the trigger mode difference.
Congrats on the SW99C. Pretty durable and reliable plastic guns, all things considered. I really like my 9mm compact model (SW999C), but thought the .40 version (SW9940C) had more snap/muzzle whip than some other compact .40's. The full-size .40 is nice, though. The compact 9mm model is very pleasant to shoot, and the 2 grip inserts essentially offer a nicely small & smaller grip circumference.
As a matter of fact, the DA and SA triggers of my 999C are noticeably better than my 3913 and 3913TSW. Accurate little gun, and it's never been fussy about any American major factory ammo I've used in it.
I got my leather holsters back when S&W/Walther America was ordering and stocking holsters in their accessory store. Mine are DeSantis, I think. (They all start to blur together.
) I've also got a plastic holster (or 2?) for my 99's for range work (in bad weather). I've noticed that a few holster makers still list holsters for SW99's, and well as combining the P99/SW99 listing for some holsters. You'd have to look around.
Congrats. The 999C's were one of the best values in a model line that was very under appreciated. S&W never really pushed their advertising for their licensed models all that much, and I was told by a couple guys at S&W that Walther wasn't really interested in having S&W (Walther America business) doing much advertising promotion when they used S&W as their importer.
Real sleeper plastic guns.

SW99c .40 SW. Cerakote - Cobalt Slide. My favorite EDC ! 
SW99c in 2020??
Hello!
I'm hoping to revive this thread on the SW99c. If anyone has one in 9mm, let me know if you would be interested in selling it. I bought a full-size SW99 on an impulse buy and liked it so much I sold my Glock 19 Gen 4.
For carry, I'm seriously considering the SW99c. If anyone has one in 9mm, I'm interested. Thank you!

I have a full size 9mm that was a Sarco re-import. When I took it to shoot at the range the first time, the backstrap started to actually crumble to pieces like bread as I was shooting it because of dry rot. I couldn't find a factory new replacement for it so I started thinking and planned to get a regular Walther replacement. Then I remembered that Magnum Research MR9 and when I looked a pictures online I realized that it had the exact same backstrap, right down to the texture, as the SW99.
So I called up Magnum Research and told them I needed a medium replacement strap. They charged me $10 and had it to me in a week. One of those times all of my random gun knowledge really paid off....I never called S&W about the part, I guess I just assumed they wouldn't have any as those guns have been out of production for over 10 years now.
Ooops....necro thread
