[ARCHIVED THREAD] - ARGHHHH MPX

So I picked up a new MPX-p yesterday. As I disassembled the pistol I noticed there was no firing pin spring. The manual shows a spring that encircles the firing pin. Mine is a Gen 2 with the keymod rail. Please tell me the gen 2 doesn't have a firing pin spring so I don't have to contact Sig to get a spring shipped to me. I'm dying to shoot it tomorrow but it looks like I'll have wait.

I have a carbine and pistol, both Gen 2. When I cleaned them and took out the firing pins, neither had a spring. It is very similar to an AR-15 and there is no spring that comes out with the firing okn either.

All is good as the Gen 2's DO NOT have a fire pin spring.
