I wanted this gun for 10 years , I just got a nice one looked great and I checked the decock leaver it was tight no problem I could see , lubed up took gun out and it ran very well . I only ran 50 or so Win 165 . looked down and no right side decock now what ? that will drive me crazy till I get what I need to fix . I dont care how much . It looked right and I looked it over I saw some one ealse lost one also .

You need the spring, plunger, and lever. Check Midway, Brownells, and Ebay. Numrich as well. You might not get them all from one place. If all else fails, PM me, I should be able to provide you with the plunger and spring.
The gun I got is a nice clean one it was issued but not much wear at all , still had the red painted safe dot on some are gone from being ultra cleaned to much . I got the gun with 3 mags and my holsters for Sig 229 with rail and some Glock holsters fit perfect. Black leather right hand open top .
Bear in mind that the older ambi levers for the 9/.40 slides were machined differently to accept the older ambi lever plunger. The newer levers are machined to accept the newer plungers. (The springs remain the same.)
The older ambi lever plungers looked very similar to the "body" plunger, having a machined shoulder and semi-flat head (versus the fully rounded head of the body plunger).
The newer plungers are straight-walled (cylindrical to the top, with no machined shoulder below the head), which gives them a wider, flat head ... and the ambi levers are machined to fit.
Mixing the ambi lever & plunger revisions won't result in the intended fit.
Also, unless they've changed it in the last several years, the 9/.40 slides with the spring-loaded decock-only assemblies use the .45 ambi lever, which has an added bit of steel "pad" which serves as a "spacer" against the outside of the slide, to help prevent lateral (leftward) movement of the decocker assembly's body.
It's just a guess ... but if someone were to have used an old style ambi lever on a new 4006TSW (because they somehow lost the new one, and just got hold of an old one from an earlier 4006, for example), the new ambi lever plunger wouldn't properly fit inside the recess on the inside of the old lever, and the lever probably wouldn't be securely held (probably being subject to be pushed out from the end of the body assembly).

Okay, I just went out to the bench and took some cellphone pics of the different plungers.
The middle plunger is the original ambi lever plunger. Note the small head.
The left (or bottom, depending on the pic orientation) plunger is the manual safety/decocker "body" plunger. Note the fully rounded head.
The right (or top) plunger is the revised style ambi lever plunger. It may also have been the original .45 ambi lever plunger, when they went from screw retention of the ambi lever to plunger retention (one of the 645/4506 transitional revisions), but I can't remember at this point. It IS the current 3rd gen ambi lever plunger for all calibers.
The pics present the plungers from different angles, in close-up, but the difference between the body plunger and the original ambi lever plunger are much less obvious when just looking at them at first glance (and without glasses or magnification).
The reason the spring is plain "color"/finish (not painted light blue) is because it's from an early 3rd gen made in '89 or '90, so whatever paint may have been present is long since gone.
So, you can imagine how the different ambi plungers require different machined recesses in the back of the levers, and why it's important for them to be matched to the same vintage/design, so they fit together properly.

FWIW, the plunger body I have for triaxle is the straight sided one with the small bevel at the top. As Fastbolt notes, using the earlier plungers with the later lever will result in a very loose fit. It will work after a fashion, but when I did a trial fit (before I read Fastbolt's last two posts) my thought was that it was very loose and likely to result in a lost lever, spring, and plunger.
What would this forum be without fastbolt? 
You guys will never believe this , I was at my 4 year old grandsons bithday party and we came home I kept thinking about how I was seated on my Atv last night and how much force was with the slide kept thinking went back up to my range which is all grass . Prayed he wants to know all concerns . I jumped off took two steps looking BOOM it was there found the leaver .

Excellent information, please be aware that the past 3 years as parts became scarce.... There was a probability that plunger and springs used may not have been for the current 4006TSW, salvaged from old 4006 parts and what not. I would urge everyone buying to check and make sure the spring and plunger are proper. When these parts come off during shooting, they are hell to locate.

Noticed on a related thread that the CHP 4006TSW's have some differences from the same vintage production 4006TSW's we were getting. Interesting, but not surprising, as sometimes a special production run for a large agency could receive some revisions requested (like the guide rods in the original 4006's they got).
Speaking of parts. How much of a parts supply did the CHP armorers have, and will those parts be sent back to S&W once all of the 3rd Gens are traded in?
What is the time frame for completing the transition?

That's hard to answer. Speaking from an area office in Los Angeles we had a good supply of spare parts about 5 years ago, but as the supply line came to a halt it seemed like everyone was trying to get parts from other offices. Parts just dried up. Surprisingly it was the plunger/spring right side decocker that was the main culprit. Being able to see these guns come in and some that saw hard use, they are very reliable. I'll see if I can get an answer to "parts" for you.
Completion of the transition is slated for 2019, obviously sooner would be better. That's dependent on a few factors like - weapons shipments and scheduled training plus running concurrent academy cadet classes.
The lost decocker lever is interesting as that's what happened to triaxle. I guess his situation isn't unusual at all, which is unfortunate.
I did get a nice gun not much wear at all and I did look at the decock and seemed ok when I got it .. I may end up with two . I have the older CHP gun and never a problem a gun guy must of had it . Has a real smooth trigger .
