Got a police trade in 4013tsw. Love it, but was worried about how loose the trigger is when it’s cocked. It can be easily moved. Anyone?

Moved? side to side, back and forth? or both?

Missing, damaged, or worn trigger play spring.

I'll bet it wiggles fore and aft.

It's not uncommon for those trigger play springs to get damaged during "aggressive" cleaning.

Some Departments (like CHP) actually instructed S&W not to install them from the factory.

The gun works perfectly fine without them, but can be a bit unnerving when first discovered without knowing why.

Back and forth

It’s a CHp trade in. Should I change out?

Unlikely its a CHP trade in - dont think the CHP ever used 4013TSW. More likely Dept of Corrections or some other state agency.

As to trigger play spring, if it was a late CA purchase after CHP specified no trigger play spring, its possible the 4013TSW also never had one. Easy to tell with simple removal of slide and inspection with good light.
If not there from factory leave as is unless it really bothers you. If broken, remove pieces or straighten as best you can and replace or leave as is as long as still functional.
Pain to replace as its riveted in.

Take a look to see what’s going on with the trigger bar.

Some LE Agencies specifically requested that the trigger play springs were to be omitted due to the potential, (inevitable,) bending or breaking. This is more common with the old style, (two “finger/tab”.) S&W tried correcting this with the new style solid ones.

My late production 4566 LE trade in did not, and never had a trigger play spring but it still had a hole for the rivet. My 4006TSW never had trigger play spring and didn’t have a hole.

It’s a personal thing whether you want a trigger play spring. I put one in my 4566 and got a NOS drawbar with a new style trigger play spring for the 4006TSW. I like the feel of trigger play spring but that’s just what I’m used to.

The CHP did issue the 4013TSW and not long ago a bunch came on the market along with a larger number of specially designed (for the CHP) 4006TSW models.

The CHP4006TSWs were factory built without the trigger play spring (I have one) and (IIRC) their 4013TSW pistols were also so equipped (or, more accurately) unequipped.

It is relatively easy to replace or install a worn, broken, or missing trigger play spring if the drawbar has been drilled for one (as 4T5GUY points out) or to replace the drawbar with one drilled for the spring.

All the double stack 9/40 models use the same drawbar.

John

Ahh yes. But as you re-pointed out to me, (us,) not all 9/40 model drawbars were the same.

Until that previous discussion I’d never noticed the difference or paid attention. The discussion was about the issues with breakage of the early “squared” drawbars. Or ended up there.

Just something to think about when replacing drawbars.

Definitely a trade in from CHP. Historical guy told me.

Trigger seems to missing the relay spring…

Looks the issue is when the hammer is cocked back. There is also play and she ace between the trigger and the bar…

Picture of the issue

I stand corrected - do you know more of the history of CHP issued 4013TSW? Why? When - before or after the 4006TSW with integral rail?

Went to the academy for CHP in October 1998 to a recent graduate as a service pistol.

You're right, Jim.

I thought about that as I typed, but sometimes I just don't feel like repeating every item of the nearly excruciating minutiae entwined in the S&W saga, and feel it's time for someone else to make the point.

And besides, not ALL of the square cornered drawbars have failed, and they do fit and work.

But good point just the same!

John

I only know that which was related to me by our fellow member, Adrian Olsen (former CHP Gunsmith with the Forum handle, "adrianolsen").

As I recall, the 4013TSW predated (by a short time) and then served concurrently with the "integral rail" CHP4006TSW.

The 4013TSW was issued to "plainclothes" officers while the CHP4006TSW was issued to unformed officers.

John

That "space" betwixt trigger and drawbar was precisely and only the issue the trigger play spring was designed to address.

By your picture, it is visible that your drawbar is drilled for the spring, just not installed.

John

Ok, not to beat a dead horse, but it shoots fine without the spring. Does it need one or cause damage without one? It sounds like it’s not an issue as it designed like that and it’s just preference rather than function… am I correct?

The trigger play spring is not needed for proper functionality. You will be fine without it.

Thank you!

As far as I know all of the CHP 4013TSWs were the earlier "pre-rail" models made from 1997-1999 which mainly had the MSExxxx & MSFxxxx serial numbers.

Their frame, slide & barrel's were etched with a CHP asset/inventory number.

Mine was made in 1998 & when I bought it in 2017 it looked virtually unused.

It does not have a trigger play spring installed in it.

Mine has the MSFxxxx serial number and the same type CHP asset type number. Pre-rail like yours. Mine was from 1998 and I acquired it a few months ago. It looks great for its age. The trigger is apparently loose and functions. I wasn’t used to it. Is your loose when cocked???

Yes, in the cocked SA mode it has some front/back play but not in DA mode, which is typical.

The trigger play springs are (for reasons unclear) more likely to break in the large frame 3rd Gens than in the medium frames.

LOL, of course you can't break it if it's not installed, which I suspect was CHP's theory & experience from the large frames.

There's no problem shooting it without that spring installed.

That is exactly how mine functions. Good to know.
