Title: S&W 1076
Post by: StockIIBoss on December 20 2013 08:45:29 PM MST
Just bought a 1076, the Da/Sa decocker model the FBI carried briefly before they asked S&W to develop something with a little less power, now known as the 40 S&W. It should make a fine addition to my 10mm collection! I haven't seen it yet, just pics, but those looked pretty good to me. And now I wait....

I appears as if someone along the way swapped out the bobbed hammer for regular hammer like on the 1006. It ought to be interesting to dig into it to see if there's more than meets the pictures... On a positive note, maybe a smith along the way fine tuned it to perfection while changing the hammer. Yeah, that's it!  :D

I actually like. I too own a 1076. You can call Smith and Wesson and see if it was done there. While you're at it ask if it is an FBI issues model.  It may be worth it to get Roy Jinks at Smith to do a history letter. I think it takes like 3 months and cost 50 bucks.

Let us know how you like the trigger. I bet you won't like it near as much as the SII.

I'm pretty sure it's not an FBI issue. No warning notice on the slide and has a mag disconnect. Besides, who wants something that's been on a sweaty FBI hip rolling around in the dirt for a couple years?    :)) 


Intercooler, now you have me curious about the trigger. Yet another tuning challenge...

I'll give you .57 cents and some belly button lint to take it off your hands.  :P I'm surprised actually. Every 3rd Gen and even 2nd Gen I've tried have had pretty good combat triggers. Is it clicking or just long and/or bad?

It just flat out sucks. The 3rd Gens are known to suck royally on the weight and feel.

I love all of mine. Maybe it is just what I am used to since I have been carrying one since 87 or so. I keep hoping to find a 1006 w/o the adjustable sights at a LGS for a deal. It's a great pistol. You'll never wear it out. I wish S&W would have release a TSW version of it with the alloy frame.

Interesting. My 1076 is at the S&W Custom Shop right now and the gunsmith told me that it is impossible to put a hammer with a spur on any of the S&W third gens with the frame mounted decocker.

The 1076 arrived today, two days early. Woo! Given the trigger comments, that's the first thing I did...pull that trigger. Hahahaha, now I know why the FBI dumped the gun. It wasn't the recoil, it was that gawd awful trigger! LOL. How do you know when a trigger is bad? Well, the double action feels better than the single action. I'm sure it's nothing that can't be fixed. Just gonna need a larger hammer....  ;D


Sweet gun, though, and appears to be in great condition. Looks like a keeper!

Congrats!
Don't worry yourself with the trigger, use it and get use to it and it will be fine.  It's a combat trigger, not a target trigger.
You'll have to get use to the takeup of the slack and the trigger reset after the first shot is fired.  Letting the trigger back out slightly till the reset point is found.
Getting replacement parts if you mess something up with the trigger geometry may be far and few between.

Here's a closeup of the hammer. Is this from a 1006?

More than likely it is the hammer from the 1006 or 1066.

They may have wanted thumb cocking ability...

This ^^^!!! You will get used to the trigger. Shoot the snot out of it and give us your opinion in a few months. Congratulations on a fine weapon!

Supposedly the S3 has an even better trigger as an upgrade. Not much you can do on the 3rd Gen.

I suppose if you have access to a CNC machine and good quality stainless steel or other metals to make your parts from, you could make stuff to suit your needs! ::)

I have two little dots underneath the decocker lever. Is that the indication that it has been through the recall?
Title: Re: S&W 1076
Post by: The_Shadow on December 31 2013 09:18:10 PM MST
Yes they two dot are the indicator for doing the recall work. Below is what was sent out for the recall...

SMITH & WESSON

Other model Smith & Wesson pistols are not affected by this advisory.

We have determined that it is possible for a Smith & Wesson Third Generation 9mm, 10mm and .45 ACP pistol with a frame-mounted decocking lever to malfunction so as to make the pistol inoperable.

In order to safeguard our customers from the possibility of such a malfunction, Smith & Wesson will inspect and, if necessary, modify these pistols free of charge. Owners of Smith & Wesson 9mm, 10mm and .45 ACP pistols featuring a frame-mounted decocking lever with model numbers listed above, and which do not have two dots stamped on the frame underneath the decocking lever (when the lever is depressed) should send their pistols and accompanying magazines to Smith & Wesson for a no-charge inspection.

Please send your pistol and magazines to:

Smith & Wesson
2100 Roosevelt Avenue
Springfield, MA 01102-2208
Attn: Service Department-DL

If you have any questions regarding this product advisory, please call 800-331-0852 ext. 211.

While we have your pistol, our armorers will stamp your pistol with two dots under the decocking lever, and give your pistol an ultrasonic cleaning and full lubrication (a $25.00 value) at no charge.

We apologize for this inconvenience. Smith & Wesson remains committed to building the safest, most reliable and finest-performing firearms possible.

Sometimes when i double action the trigger, the hammer fall on the half cock notch rather than all the way down. Is this the problem that cause the recall, or do I have another problem?

I looked under the decock, and i have the two dots, and the dimple on the grip, so I am up to date. Unfortunately, if I pull the trigger slowly (double action) the hammer sometimes get's captured by the half cock notch. I guess it's going back to S&W anyway.

I sent two back to the factory and they did not put the .. under the decock lever. Appears they are not doing that anymore

Yeah, makes me think this might have been an aftermarket part, unless S&W offered these as an option at one time.

Finished up a mod to improve the 1076 trigger take up. Check out the video and let me know what you think. "After" begins at :20





Title: Re: S&W 1076
Post by: The_Shadow on January 19 2014 03:10:00 PM MST
Did the pull get any lighter?

What mod did you do to the action to get your results?
Title: Re: S&W 1076
Post by: StockIIBoss on January 19 2014 03:54:33 PM MST
You can't hardly feel the remaining take-up, but the pull for the break is not improved. In the case of mine, it's not a heavy break to begin with, and very clean with little to NO creep. I can actually get all the take-up out of it, but it's a fine line between zero slack and a clean, reliable reset. It's just best to have a little play in there just to make sure. Then again, this is dry firing. When shooting live rounds there will be enough forces and movement that a super short take-up wouldn't be an issue at all. At this point, I'm still playing with the various (ok, two) ideas I have.

The simplest mod, and what the video shows is filling the gap between the rearmost hammer hooks to the rear of the trigger bar. Just remove the grip pin and remove the one-piece grip. You'll see the rearmost hooks on the hammer and the relationship to the back of the trigger bar. Even though it looks easy enough, ensuring it works in various trigger positions is another matter. I started with a nylon block trimmed for space for the mainspring support rod, then started sanding it down to fit. You'll see where the spacer block has to come in at an angle to ride over the spacer and not get jammed by it. With the proper angle and thickness you can actually get the double action pull to have little to no take-up, and in this gun, the same as the single action. Pretty cool. The half-cock (or decocker) position is another matter and can't be tuned independently of the other positions. It is what it is, but no big deal, and my goal is really just to improve the single action take-up.

Next concern is just how 'permanent' do you want this mod to be? For testing I simply glued the nylon block (spacer) in position with Loctite super glue. Holds just fine for testing purposes and allows for easy removal for tweaking. If you want a permanent fix, it needs to be a mechanical part of the trigger bar. I'm thinking of solutions for that, keeping in mind that these parts aren't that readily available in case you're having a bad 'smithing' day. I hope to come up with a way to have an adjustable spacer without folks having to hand-fit the parts. Pipe dreams? You can't modify the hammer because of the installation space, so you're limited to the trigger bar. An adjustable wedge is possible with the available space, but then it becomes a precision smithing job. Anyone who wants to jump in here and exchange ideas would be very kewl.

Thanks for the explanation and details!  If there was something that S&W could have done to make these pistols better it would have to be the triggers.  I know they were that of Combat/LE use but the trigger pull and take up could have been made better!

Shooting many different makes and styles I have to retrain myself mentally before hand, for the take up... :-[
