All,

Just spoke with my nephew who is a SWAT cop in a large city.

He is telling me that their new SIG pistols (Legions in .40) and the patrol guys P226R pistols (also in .40) are having light primer strikes.

He has been told that this is because of improper field stripping of those new guns with the SRT (all of their new guns have SRT).

They are telling him that everyone needs to be retrained on how to properly disassemble the guns to avoid inducing the light primer strikes. They are telling him he needs to "hold down the de-cock lever or it fucks up something with the firing pin resulting in light primer strikes"

I immediately told him that this is bullshit and that SIG is telling them this to stall while they figure out what is up with these guns.

Am I wrong?

I know early SRT equipped guns required that you depress the de-cocker to field strip, but this is because the slide would get hung up. They later fixed this with a modification to the slide (based on what I have read).

My 12+ SIGs all have SRT's in them. They either have SIG factory parts or Gray Guns SRT parts. I have never had a light strike on any ammo I run (including steel cased) except for 1 gun worked over by Gray Guns (a P239), and Bruce fixed that for free. I also have no issues taking down the guns as described in the owners manual. All of my guns are manufactured after 2008, except for a P6 I have and a 225 (they are the only guns not with an SRT installed).

I really think this may be a bullshit excuse and I am concerned that my nephew may have a failure when he really needs the gun to work because he is listening to his armorers and SIG.

If I should post this in the Armorer's section, I will.

Please help me out with understanding this or if it is bullshit.

Bruce... Because he is carrying a Legion, I would like your input if possible due to your expertise and involvement in the Legion project.

Thanks.

DansSIGs...

I know this, but I thought this issue was resolved some time ago.

These are brand new SIG's.

And even then, I don't see how this could affect primer strikes based on my knowledge of the gun (have installed several SRT's myself and do not have to do anything outside of a normal field strip). I understand it may hang up the slide during removal, but light primer strikes?

If you wear/break off the tip of the FP safety lever, then it might not press the FPS all the way during a trigger pull and hang up the firing pin a little.

But that is conjecture. All of my P-Classic Sigs have the SRT. Most are SAO and only one - P225A1 - is DA/SA. I see nothing in the action of the FPS lever that would require a de-cock during takedown.

Now, holding the trigger back and trying to remove the slide will cause it to hang up on the lever, and forcing it could conceivably damage the lever.

For people used to taking down a Glock after pulling the trigger, it's plausible they might be holding the trigger as they remove the slide, but they would have to be holding the trigger fully back with some force which to me would be odd.

Lefty... Thanks. They have been using SIGs for a while now (nephew had to turn in his 226 TacOps for the new Legion). I do not think he pulls the trigger during disassembly, but I have not asked either.

DansSIGs... That was my thought. Only light primer strikes I have ever seen in a SIG has been when the owner had changed the hammer spring to a 19 lbs spring. It would work on most US practice ammo, but the steel case Russian stuff and some defensive loads didn't like it (hard primers). I thought SIG only used 21 lbs hammer springs?

Bump... Anyone else who can add to this?

Didn't know this was a thing. Granted that I only have three P-SIGs with SRTs (two P220s, one P226; all factory-installed). None of them have ever had any issues with field strip takedown or reassembly, nor with any resultant 'light primer strikes'. I've never held down the decock lever when removing the slide assembly from any of those three. All have birthyears 2009 or later.

I also have 3 P-Sigs 2 P229 and 1 P226 tacops all have SRT and I have never used the decock on field strip and have no issues with them either.

Through the years, I’ve upgraded multiple P series pistol I’ve own with SRT mods. Never decocked them prior to disassembly & never experienced an issue..

I have three p series Sigs with the SRT kit installed, and have never followed that procedure when field stripping, and have never experienced an issue with light-strikes.

At least half dozen with SRT, I just decock when removing slide. No problem doing it that way. No idea if I have to or can skip that step. Do not know why I should or could.
