I have one. Just took it out a couple of months ago, after it sitting in the safe for years. I've had no problems, except this is one of the few guns I never purchased extra magazines for and they apparently are really expensive (about $50 each + shipping from what I saw when looking recently). Remington no longer stocks the magazines apparently.

Many individuals experience failures due to the need of a full dis-assembly, cleaning and lubrication from alot of dirty and cheap ammo. Keep it maintained and you should be good to go.
