Sigma trigger rubbing trigger guard

Everybody knows the Sigma trigger is tough/bad, but mine seems especially so. My trigger finger is literally bruised for days after even modest range sessions (150-200 rounds).

Today, while dry firing (to continue to loosen it up as much as possible), I noticed that the bottom of the trigger actually makes contact with the trigger guard, and fights against that friction for the last half of the pull.

Is this in any way normal or fixable?

Dunno about normal, but fixable? See, there's this stuff called sandpaper...

ha, I guess I deserved that. That had occurred to me :)

If it's not normal, I'm wondering if S&W will fix it in a way that won't hurt re-sale value like a permanent, homemade fix.

Post a couple of pics. 1 with trigger at full reset and 1 fully engaged. I don't think the trigger should drag against the inside of the trigger guard, if that's what you're saying.

BTW, don't worry about resale value. It's not that kind of pistol. It will probably always fetch somewhere between $200 - $250 used regardless of the possible trigger "issue".

How long has it done that, since new? If a recent issue, I would be concerned that the trigger pivot area has a problem and the trigger has somehow dropped lower in the frame.

Onward, will do - but can't until tomorrow.

Yes, you are correctly understanding what I mean. It is dragging against the inside of the trigger guard on the way back, and is actually wearing into it.

I have no reason to believe this is new - it is far more likely I just have not noticed it until now.

I can only tell you what I'd found on a couple of my Sigmas just now. As you already know, the trigger is two parts and is part of the built-in safety. The lower part pivots when engaged and there is about 1 mm of clearance between the bottom of the trigger and inside guard. The trigger never touches the inside of the trigger guard.

Call Smith's customer service

tell them the trigger is rough and gritty

DO NOT tell them it is "stiff"

they'll email postage

ship the frame to them

about 2 weeks later it will arrive GREATLY improved

I have actually done that. But the ending was not as promised.

My front sight fell off, so I sent it back to them, and I also mentioned the trigger was rough and gritty, just like everyone said to.

Their return letter to me said that they did a lot of work on the trigger. I call BS - it's the same as it was. This was 500 rounds ago.

The trigger as it normally rests:

Beginning the pull. This is just before the point of contact with the guard:

I'm no photographer, obviously. This is the bottom of the trigger directly contacting the guard, and dragging against it:

It stays in contact until the trigger is 'bottomed out' - i.e. pulled all the way back:

There are also some wear marks on the inside of the bottom of the trigger guard from the friction with the trigger, but I could not get a shot that showed it.

Pic #1 and #2 look exactly like mine in the same position. Pic #3 is where mine gets closest to the guard but it doesn't touch...maybe 1 mm of clearance. Pic #4 is where mine will touch the back of the trigger guard...maybe normal? I definitely don't have grooves or any wear on the inside of the trigger guard though.

I would call the factory and maybe email them the pics just to make sure it's ok for this to happen.

Having it come so close that it actually leaves drag marks surely cannot be normal.

s&w will fix it for free.

i don't think resale value of a sigma should be a concern for anyone....:eek:

So you said this:
I have no reason to believe this is new - it is far more likely I just have not noticed it until now.
And you recently sent your gun to SW, and they said this:
Their return letter to me said that they did a lot of work on the trigger. I call BS - it's the same as it was. This was 500 rounds ago.
Perhaps the dragging trigger was the result of "a lot of work?" :)

It will probably always fetch somewhere between $200 - $250 used regardless of the possible trigger "issue".


sigmas have been on sale in my area for $250 brand new very recently. expect a used one to fetch no more than $150.

I had one that did the same thing. 30 seconds with some sandpaper on the bottom of the trigger fixed it.

The ultimate fix was when I traded it for an M&P. Got $225 for it, I was happy.

The resale value on a used sigma?
