Lost CHP 4006 decock lever right side

Let us know if the new parts fit and if they correct the issue, then please also give us the part numbers... Looks like this may be a good combo to add to our spares box.
 
I had my right side lever pop off last night. I was clearing it to begin some dry fire training and when the slide went forward the lever came flying off. The plunger and the spring stayed in the slide, I had to place them downward and tap to get them to come out. The spring was broken so there was no more tension on the lever. I ordered a new plunder and spring from Brownells. I could only find one plunger listed so hopefully it's the correct one. From the descriptions in this thread it looks like I might have had the old style.

Unless something happened to damage the plunger, if it's just a broken spring involved, the broken spring can be replaced with a new one and the existing plunger still used.

The spring is the same for both the older and the newer ambi lever plungers. (Ought to come painted a light blue color.)
 
I updated the pics in a previous post (having had to change from Photo Bucket to another hosting service when PB stopped allowing 3rd party sharing).

Also, here's a pic showing the current ambi lever plunger and spring (both new parts), as well as a manual safety/decocker assembly "body" plunger and spring.



You can see how the body plunger is thicker and heavier. It can't be compressed between your finger tips like the much lighter ambi lever plunger spring can be compressed, and it's unpainted (no "color" code).
 
Thank you for the pics! My plunger and the one I ordered look like the correct ones, and the spring I ordered is blue (as long as Brownells pics are good).

My broken spring is definently not blue, not a trace, and actually reminds me of a magazine release spring. Could that have been mixed up and installed?

The two part numbers I ordered were:
Ambi M/S Body Plunger (Brownells) 940-000-574 (factory) 230150000
Ambi M/S Lever Plung Spring (Brownells) 940-000-318 (factory) 106020000

Also ordered three 11 round magazine springs. Of my three mags only one will accept 11 rounds; the other two only accept 10. The 11th will not fit. These two have springs with no color on them (and are installed correctly). The one that will accept 11 rounds has blue on one end.

Magazine Spring (Brownells) 940-000-450 (factory) 204550000

I'll keep the plunger I ordered as a spare and might order another spring. I picked up a few mainsprings, recoil springs, firing pin springs, and a firing pin. This was the first failure I ever had on a third gen :)

The mags for my 4006 are the same. One with a yellow follower holds 11 rounds. Two with blue followers and slightly different lettering on the housings only hold 10.

FWIW, the 11rd mag springs can be really strong/tight and make it difficult to load that 11th round. ;) I often had to help a few people load that 11th round, but they'll relax a bit as they're used and get easier (I didn't say "easy").

The shorter 9rd 4013TSW mag springs are not only a little shorter, but also have a noticeable upward "bend" (facing toward the front) in the top coil.

When present (depending on vendor), the 3rd gen .40 mag springs for the 4013TSW & 400X may have a light blue bit of color code paint, but the CS40 mag springs (last time I looked) are green. (Just to keep us guessing, maybe? ;) )

There should be no difference in loading an 11rd 400X mag spring to full capacity just the follower is yellow (older) or light blue (latest revision).

The mag catch spring is a different diameter and longer than the ambi lever plunger spring.

Yes, if someone not really familiar with the various small coil springs used in the 3rd gen guns were to look at them all in a pile (outside the gun), they can start to look alike. :confused:

I don't remember when they started to color code the ambi lever springs, so it's possible an early vintage spring might not have any paint ... but ... consider that exposure to solvents & CLP's can also rob color from springs that originally had a light paint on them. ;)

I don't know what the difference is but there is no way that my two blue follower mags will accept 11 rounds, even thought it looks like they should.

I own my share of automatics with tough magazine springs and trust me, these will NOT accept 11 rounds. Here is a pic of the two springs. The one on the left will accept 11, the one on the right will not. The spring stacks up when you try to fit the 11th. Not sure what or who's spring it is. Anyway got the three factory ones on the way this week and I'll compare them all.

Good info on the mag release spring. It looks similar but I think my safety lever spring just gave up the ghost. I'm sure it's seen quite a bit of use!

My 4006 was mfg in 12/92 and is a former Tulsa PD unit.
It has no decocker.
DA only as well.
Will hold 14 in both mags.
Ive owned it about 4 yrs now.
Good shooter I enjoy it.
I just picked up a 4516-2. I posted a thread on it.

Here's a mag catch spring alongside an ambi lever plunger spring. The smaller spring (light blue tint) is the ambi lever spring.




Sorry I can't help with pics of the 11rd mag spring for the 400X guns, but I neither own a full-size 400X gun, nor do I remember having any left-over 11rd mags in my collection of mags.

I do, however, have a lot of 9rd 4013TSW mags, and I just took some pics of some springs.

Except for the shorter spring with the follower in it, the other springs are all brand new/unused.

The shorter spring with the follower in it is from back around '06, and the other springs are new replacement spares I've ordered, ranging from several years ago (maybe the age of the used spring), up through a few months ago, and even last month. The source was directly from the factory for all but a couple of springs last month, which I added to a Midway order on impulse (marked as a factory spring).

The springs haven't changed in general appearance for several years (part # 26256), although I have no way of knowing if there's been any changes not discernible to the eye. (No revision numbers in the part number on the latest order I received from the factory, though.)

Note the upward "bend" to the top coil, presumably because the shorter & lighter slide of the 4013TSW generates some faster cycling. You can't see it in the pics, but the end of the bottom coil of the new springs I checked has a bright blue "dot" of paint on it.

The last 11rd mag springs I remember seeing when I had a mag apart on the bench at the range had "normal" coils at both ends, and I recall there being some blue paint on coils at one end. Don't remember the number of coils (windings), though.

I do remember they were generally difficult to load, and the last (11th) round could be quite difficult.

I imagine if someone were to order new factory springs from S&W, presuming they have them in-stock at the moment, the company would send whatever current spring is being used.

The pic of 3 springs includes new/unused springs from 3 different time periods over the last several years, from a couple of angles. The used spring alongside the bunched springs is off a roughly 10 year old spring and the new factory springs I received a few months ago.

Wow there is no way you could fit a magazine catch spring in there huh? That's a definite difference. My springs should be here on Monday so I can compare magazine springs. I also have a new 4006 magazine I bought about ten years ago when I got my CSP 4006 so I'll dig it out and compare the springs.

Thanks for the info!
 
The 4006 CHP I received from Summit has three mags with blue followers and what seem to be springs with the upward bend in the top coil as Fastbolt posted for the 4013TSW. An older yellow follower 4006 mag has a spring without the bend in the top coil, but is noticeably longer when compared to the CHP magazines, it looks the same length as a 5906 magazine spring.

Adding to the mystery, I also noticed that Wolff sells the replacement mag springs for the 4006 under the same part numbers as the shorter 6906 magazines, rather than the 5906 magazines which are the same height as the 4006.
 
FWIW, the last parts list I got (2013) lists the older 4006CHP 11rd mag as using the same 9rd mag spring as the 4013TSW, part #26256 (probably at their request) ... but the 11rd mag spring for the 4006, 4006TSW & 411 lists part #20455.

We never had to replace any mag springs for the new production (mid 2000's) 4006TSW's we used for a few years, and we didn't order any spare springs. Now I wish I had one at hand to look at it.

If I were going to order new springs, I'd call and make sure the customer service person taking the order knew which model/magazine I was using, so they could check to see if any revisions have occurred.

Maybe that CHP officer on the forum will see this thread and check one of their current mags, to see what spring is being used (and count the coil windings, as that's a lot of windings in that longer spring that someone posted above).

Dunno.

However, I wouldn't rule out someone (previous owner?) having ordered/used an aftermarket spring, and gotten the wrong spring to use in those S&W 11rd mags.

BTW, the 15rd 59XX mag springs use a completely different part number. Ditto the 12rd & 15rd mag springs being different numbers for the 69XX/59XX mags.

Also, aftermarket springs may have different wire gauge, heat treat and dimensions, as well as the number of windings, compared to the factory (vendor provided) springs. Factory springs may involve one set of specs, and an aftermarket manufacturer may use different specs, but which they feel will provide the same function (even if they look different).

The only mags I have on hand right now are yellow followers.
I just DROS'd my 4006TSW and it has 3 blue follower 11 round mags, actually everything exactly the way I turned it in, when I was issued the M&P. Unfortunately I have been so busy I just stopped into the FFL today and still have to wait 10 days. I'll break them open when I get it, but I remember the magazines were a pain to load to 11.

If memory serves me right we actually switched mags about a year or two into the TSW. The new mags were extremely hard to load to 11 rounds. Some so hard that only a mag loader UPLula would be the only way to get 11 rounds in them.
