Question on Folded German slides and +p ammo Login/Join 
I'd rather be hated for who I am than loved for who I am not

I recently had a discussion on a facebook sig group about folded slides.

A gentleman was stating that 226 carbon slides would shear off of the breech block when fed a diet of +P ammo and that's why they went to stainless milled slides. I feel that most European ammo is considered +P

My belief is that there was no such problem and the stainless slides came into effect for 40/357sig and it was just easier to make them the same way.

who is right?

also what would the results be if this were to happen?

I don’t know what that means, but I know of no restrictions on using +P ammunition with older Classic line SIGs. I wouldn’t use +P in the early “mud rail” P226s, but then I wouldn’t shoot them at all if I wanted to keep such a gun for posterity.

Years ago when I attended my first factory armorer course, I asked about an ejection issue I was having with a P225 and the very knowledgeable instructor said to shoot hotter ammunition because that was what the gun was designed for. +P ammunition was in use long before SIG switched the P226 slide to stainless steel; did you ask him how he knows that that was the supposed reason for the switch? What about the fact that SIG abandoned the carbon steel slides for all their models; was that due to the use of +P ammunition? Roll Eyes

Grayguns offers a heavier recoil spring for the 9mm P226, so if I were going to shoot much +P stuff through one, that’s one thing I’d use. I’d also replace the recoil spring every 2500-3000 rounds and the roll pins that hold the breechblock in the slide every 5000 rounds.

no he basically stated that they shear off and the breach block separates. But I have never heard or ready anything of the sort.

But I am no armorer

Still makes no sense what that means. But, whatever. The guy was blowing plenty of hot air, there.

We were taught in the SIG armorer schools that any SAAMI or NATO spec ammo was approved for use in SIG pistols, folded slide or one piece milled. No difference in approved ammo. Our local police department issues +P ammo for officers carrying 9MMs. Some carried the folded slide SIGs. All the guns came through the armory once a year for inspection,repair,etc. I never saw any indication of increased wear or damage due to use of +P ammo.
