Sig P220 - Firing pin swipe

[Steve in PA]

Went shooting my P220 this past weekend, everything went ok. I reload/handload so I picked up all my brass and when I looked at them I noticed a firing pin swipe on it. I know some weapons leave marks on the primers, my Beretta 92FS leaves a dimple.....nothing wrong with the gun, has always done it....just wondering about the swipe.

My SIGs, as well as a friend's P228, do the same thing. Nothing to worry about.

Thats not quite the case.
A lot of SIGs will do this... showing firing pin drag marks can be common... but it is NOT something to shrug off.
You need a SIG Armorer to take a look at that and even replace the firing pin spring - because drag marks mean you could have a pin break on you some time.
I carried a P220 on duty for some time and I noticed that... Drag marks. I took it to my armorer and he instantly tore it down and had me come back a few minutes later. I came back 15 minutes later and found my gun to be in perfect condition. No more drag marks... My pin? Ruined. It could have broken on me.
