I hope this question does not make me sound too bad, but I have 220 10mm Legion that I shoot a lot. I am looking to get a recoil spring replacement. Does the captive set up come apart ? Do I just buy a completed recoil spring assembly or can I just buy a spring ?
As I look at the assembly I cannot see how you get an end off to take the spring off.
Any help would be appreciated.
Thanks !

You need to buy the complete assembly from Sig.
I believe the part number is 1202817-R.

Thanks. Any idea about how many rounds I can go before its recommended to change it out ?

I was told 3-5000 rounds.
