Sig SP2022 Two-stage SA Trigger?

[marlin795shooter]

Picked up my Sig SP2022 yesterday and was practicing dry-firing it and noticed that in the single action trigger, there's two clear stages to the trigger before the break. Both are light, but there's definitely a change in the middle. So it's half an inch of stage 1, half an inch of stage 2, then break. I have stripped, cleaned, and greased the gun.

I don't notice this on any of my other DA/SA pistols. Is this normal? Strangely I noticed that with the slide off there's only a clean one stage pull before the break.

There is an INCH of pretravel in your SA trigger?

Is there a pretravel adjustment you can do?

Does the gun have a firing pin block? That might be what you are feeling as the first stage??

[marlin795shooter]

I may be overstating the pre-travel, but the main thing is that there are two stages. Wikipedia says it does an automatic firing pin lock though I'm not sure that's the cause. I don't feel two stages in DA mode.

Looking more closely at this, it does look like the firing pin lock is what causes the second stage in the pretravel. The lock doesn't raise until about halfway through, which is where I feel the added weight. On my sig mosquito it raises from the start of the trigger travel. I see no way to adjust this.

Is that normal? Does anyone else with an SP2022 feel the same two stages?

Keep shooting it...it'll smooth right out.

I have one in 40cal but I don't remember the SA trigger having the pretravel. It's pretty short and crisp on my.

It sounds normal for the technique you are using.

It sounds like you are describing the pre-travel as the first stage and the actual take up as the second stage...the FPS is raised during the take up. There are actually 3 stages to a trigger press. 1) pre-travel (taking up the free slack), 2) take up (after contact of the trigger bar with the sear) of the engagement travel and 3) release of the hammer by the sear.

I don't fully release the trigger when setting up a SA followup shot. I release the trigger to the reset point and press through the take up to the release

I have the .40 and for SA pull, I don't feel what you have described.

Just shoot it. My wife's 2022 out of the box had me wondering why everybody was raving about the trigger. It was like dragging a bag of sand through a gravel pit. After several range trips & cleanings I guess whatever burr was hanging things up worked itself smooth. Function checking after cleaning was It's GTG now.

My own was like buttah outta the box.

The lever that lifts the firing pin block doesn't begin to move until nearly the end of the trigger travel. This is to keep the firing pin blocked until the trigger is nearly fully depressed to help prevent unwanted firing of the weapon.

The second "stage" you are feeling is very likely this safety lever interacting with the firing pin block.

Remove the slide and dry fire. If the symptom is no longer present I would definately conclude this explaination to be accurate.
