I've got a sig 220 that has been leaving drag marks on the primers of fired cases. I believe this is a sign of a tired recoil spring, but want to confirm this with someone who has more sig expertice than me. Also, the gun has been dry fired a bit, I know this because I bought it from a friend of mine who loves to snap his guns. Could the firing pin be burred and sticking? Help me out bro's:thumbup:
 
I haven't heard the term drag marks used on primers. Can you take some pictures to explain what you are talking about? I am not particularly familiar with the SIG. Can I assume that it has an inertia type firing pin?

Don't know how much use I'll be but I am interested enough to look. Can you see any visible burr marks. If you can see any, can you use a stone to remove them?
 
i have seen a 1911 IIRC do that, on it it was IIRC the recoil spring but i could see where if the pin was sticking it would do that too, you should be able to look and see if its sticking though.
 
Replace firing pin and firing pin spring. Your pin isn't retracting properly.
Never dry fire with an empty chamber , use a snap cap. Never dry fire if the manufacturer says not to .
 
A light oblong drag mark is pretty common on a lot of semi-auto handguns. Seems to be worse on compacts and sub compacts, especially .40 S&W's. I've changed out a few firing pin and springs with no improvement seen.

Yeah, I know the whole "my friend did it" thing makes me look like the guilty one but it's the truth, and I agree, snap caps are the way to go. :thumbup:
 
Replace spring with a Wolff xtra power, most factory springs are a tad light after the firearm is broken in.

I guess my first question would be are you having any malfunctions? Stovepipes, failure to extract or any other feed or extraction issue?
