Is this normal?
I have a 930 SPX that I bought last Oct, and love it, performs flawlessly. I had to send the barrel back, though, for the dreaded canted front sight. While waiting for the warranty repair, I decided to purchase the 28" smooth barrel so I could use it for sporting clays. Looks a little funny with the extended mag and pic rail, but hey, it works. Anyway, after shooting a round of clays, I took it apart to clean it, and noticed the gas piston was not seated back in the gas cylinder, but was jammed partially extended. I've cleaned and shot the gun a few more times, hoping it would loosen up, but it is just darn snug in there when the gun is assembled. The piston slides easily over the mag tube, and out of the gas cylinder, when the gun is disassembled, but binds when put back together. Funny thing is, it operates perfectly, never failing to extract or to load a new shell.
Question: should I be able to move the piston out of the cylinder with finger pressure, and should the return spring bring it back into the cylinder with no additional assist? If this is not operating correctly, any thoughts on what could be wrong? Could it be that the gas cylinder and the magazine are not parallel? I spoke with Mossberg, they want me to send it back, but I'm still waiting for the short barrel, I don't want to send the gun out if this is "normal". Thanks!
