Nope, I bought it from UNcompany and it came in retail packaging. I'm thinking the valve is stock since it looks identical to the other mag that came with the gun.
That makes sense that if it's not a hi-flow causing extra resistance maybe the valve is harder to depress because something is causing it to stick harder than it should.
Hmmmm I might just drip some silicon in that area and let it sit for a few days face down so gravity can let it seep into it.
