SIG P6 Trigger Pretravel?

[Blind Bat]

I posted this on XD Talk but I didn't receive a response so I'm going to repost here in hopes of querying a wider audience. I hope no one minds.

I received my surplus P6 at the beginning of April and my only complaint is that the trigger has way more per-travel in SA mode than any of my other pistols. I replaced all of the springs except for the striker and striker safety and the problem still persists. I did detail strip the P6 but didn't notice anything that looked excessively worn.

My Measurements -
Pre-travel trigger movement: 5/16" @ 1.5lbs
Trigger movement past pre-travel (break): <1/16" @ 4.5lbs

Is this normal for the P6 or do I possibly have a worn out part? If this is normal, is there a way to adjust/limit the pre-travel in SA mode?

It's not a defect, it's a safety feature.

IMO: Even cocked, a P6 SIG is safer then a Glock because of it.

Almost all military weapons have a two-stage trigger like that to prevent ND's in combat.

Any idea what is SIG's specification / tolerance is for SA pre-travel?

I do not know the specs but the all you can do is send it to Bruce Gray.

Reduced Reset Comprehensive Duty package

Full detail strip and cleaning of all parts, full Certified Armorer's Inspection,GGI Reduced reset for duty applications, detailed refit & refinish of all internal parts, Feed & Reliability and test fire along with sight regulation.

Yours sounds just about perfect.

The P6's coming in were very lightly used by the German police, and I have yet to see one that is by any means "worn" out of spec.
Most of them show no internal wear at all in fact.

I wouldn't call it a safety feature. It probably has more to do with the gun being a SA/DA decocker setup. That's just the way the mechanism is. Just about all other SA/DA guns are that way.

So are 03 Springfields, 98 Mausers, M1 Garands, M-16's, 1911's, and others.

And they are not SA/DA.

It is a safety feature on military design weapons.

I agree with that. Sig is worse then most in this respect. Longer than necessary SA is simply part of the deal.

Newer P series guns can be sent to SIG for their SRT trigger but I am not sure if they can do it on a P6 or P225 since they no longer support that product in the US.

Does the 1911 have a two stage trigger?

 

[rellascout]

It is not a safety feature IMHO.

It is a characteristic of the classic Sig design nothing more.

Hmm

I have some 1911 pretravel, but the take up weight is negligable...

I agree, the long slack in the trigger is not a safety feature. If you'll notice, many DA/SA type pistols have long slack in the trigger.

Beretta 92FS
SIG P-series
HK USP
HK P2000
Walther P99

etc...

It's just a characteristic of the action. My P226 is the same way.

Edit: I should clarify I'm referring to the single action portion of a DA/SA trigger.

The takeup on both my box stock commercial P225 and my GGI Competition P226 are about the same. As near as I can tell by holding a ruler up to the trigger guard, 5/32" on DA, 5/16" on SA. Sounds like the O.P. gun is pretty standard.

Reset is hard to measure by eye and ruler, but it is about 1/4" or 5/16" on the stock P225, no more than half that on the GGI P226. Likewise overtravel, perhaps as much as 1/8" on the stock P225 and 1/32" on the GGI P226. (When I sent it in, I told Mr Gray that minimum overtravel was worth more to me than reset.)

Do not mistake takeup for the first stage of a two stage trigger or reset for the second shot. I learned that takeup was movement of the trigger alone with no actuation of the rest of the firing mechanism. The first stage of a two stage trigger is pulling the sear partly out of engagement with the hammer or striker at high leverage, low force, long movement. The second stage to fire the gun has less leverage for a short "crisp" break at higher force with almost imperceptable movement in a good example.

A 1911 does not have a two stage trigger. It has a little necessary takeup to allow the action to reset and sear up but not two stages. I had to have a gun with too little takup corrected last week. My Colt commercial AR 15 does not have a two stage trigger, either.

Here is what happens when a standard P-series SIG is fired in single-action:

• The trigger bar rotates the safety lever.
• The safety lever pushes up on the safety lock, thereby unlocking the firing pin.
• After the firing pin is unlocked, the safety lever presses a shoulder on the sear, thereby lifting the sear and dropping the hammer.
• When the slide recoils, the trigger bar is pressed down out of engagement with the safety lever, and the sear, safety lever and safety lock spring back to their original positions.

The long SA travel of the trigger is a result of the need to unlock the firing pin before dropping the hammer.
