Trigger question- is this as it should be

[Raised on a Deere]

With the slide removed and the seer disconnect re-engaged, as I pull trigger toward the seer, the engagement with the seer is only about half the thickness of the trigger. Gun is new and only fired a few hundred times including dry firing and I can see that the wear polishing is also on about one half the thickness of the trigger.

Just wondering if I should take it to a gunsmith; sure hate to send it to warranty so ignorantly and also be without gun this summer. I have learned enough from reading this forum to know I am no where near ready to tinker with it. A lot goes into the safety of operation and I don't want to upset the safety balance. This is my first pistol. Always shot someone else's as they worked on getting me hooked on guns.

I have an excellent pic but haven't gotten the hang of uploading yet.

Are you sure those are indentations on the sear? The sear is steel the trigger bar I believe is alloy or whatever it is it's softer than the sear. It's more likely they are metal deposits from the trigger bar. I think there's more to this story than you are giving.

I don't understand the question.
Are you asking about how much the trigger bar engages with the sear?
I would ask if the gun is functioning properly?

The trigger bar looks bent and the sear itself has gouges in it from some tool. Take it to a 'smith and have him replace the damaged parts.

Gun is functioning fine. Just wondering about only half the thickness of the trigger engaging the seer. I see no actual wear but the polishing or rub track on the top of the trigger cramming surface confirms that in actual use the trigger is only partially under the seer.

Eventually as it wears, my thinking it would occur prematurely, but not being familiar with the gun maybe I am on to nothing. Just doesn't look right to me right now.
Gun is new Never been tampered with. Guess I will go to a store and examine another for comparison.

I suggest you watch this your sear should not have indentations on it.

Call S&W on Monday. That isn't right.

Took another look at my picture to so what was evoking some of your responses. Sorry I did not notice the things that look like intentions. That is oil streaks amplifying the light somehow. In person the parts look pristine and high quality finish. It is just the lack of full bite under the seer that in questionable to me. Took a look at the video. thanks. I will call Smith-Wesson Monday but perhaps I will take to gunsmith. Need to get to know one anyway. My wife is thoroughly loving the M&P 22 compact and I am really enjoying learning about shooting. So we rain it for the duration��

Do not take your gun to a gun smith. That will just cost you money and do nothing to make your gun work better. There is nothing wrong with your gun.

The part you are concerned with is called the trigger bar loop. It is the part of the trigger bar that moves the sear. It's not uncommon for the trigger bar loop to sit only partially under the sear. It's not a defect. It's just the nature of the manufacturing process.

The gun in the video I made (posted above) is an M&P 40 and the loop sits fully under the sear. In my M&P 45, the loop is more like yours. I have over 2,000 trouble free rounds through my 45.

What you're seeing is a non-issue. Shoot in good health.

Fantastic�� at least I learned how the trigger works exploring this issue.

In my early work life I worked on office machines, typewriters printers and such and the way things connect and contact was always an important part of things.

Apologies Rastoff forgot to credit the video to you it's excellent work

It's as it should be.
The way the gun works is that when you pull the trigger, the trigger bar contacts the sear at the front to lower the back end of it to release the striker.

The part you don't see when the slide is off, is that the reciprocating slide will knock the trigger bar to the right side of the gun (and moving the trigger bar loop out from under the sear, sideways).


So to see the parts in action with the slide off, you would pull the trigger, manually shift the rear portion of the trigger bar to the right (see the sear reset), then release the trigger, and repeat.

Your concern seems analogous to folding knife lockup engagement percentages, and I think in the same way, a 100% surface meeting/lockup is not desirable.
