Hi All,
I recently bought Stoeger M3K from EE. It comes with tube, extension (+3) I believe.

The gun is marked for 3" shells. As such it can hold 6 2.75" shells.

I am however able to load 9 shells in the tube. How do I bring this in compliance?

Thanks
 
1. Unscrew the +3 extension.
2. Done.

To keep using the extension legally, you need to install a plug so that the mag cannot accept 6 rounds of 3". If you make it fit ~5.8-5.9 rounds of 3", it should swallow 6x 2.75" comfortably. How to do that, depends on the extension: a metal rod in the end cap, or a second follower riveted at the appropriate depth - as long as it is permanent and doesn't cause mag spring to bind and get stuck. Or just sell it and buy a +2 extension.
 
I carry a print off of the FRT on that gun in my multi gun folder as it actually states 7rd capacity of 3" shells. Magazine capacities for semi auto tube feed shotguns is the worst to get your head around. The general rule that the majority follow is 5rds of the longest shell the gun was chambered for. However, in a non-restricted rifle, if you take a 30rd magazine and stick it in the gun, the firearm doesn't suddenly change the classification and become prohibited. It's the magazine that's the regulated item which is a prohibited device. So, if you extend the capacity of a non-restriced semi auto shotgun to say 8rd, the gun itself doesn't suddenly change classification so we need to ask, is the magtube extension a prohibited device? This confusion is why manufacturers have opted for 5rds of 2 3/4" so you won't ever see a new manufactured semi auto shotgun with a capacity over 5rds of 2 3/4.

Unlike a detachable magazine, the tubular magazine is part of the shotgun, which would make the shotgun itself prohibited with the extension installed. The magazine extension in itself isn't an actual magazine, it only becomes part of a magazine, when it is installed on the shotgun.

That could be the answer but I doubt even yourself is completely 100% certain on that answer. The argument would have to be made on the definition of detachable as the tube extension is most certainly detachable. From what I understand, a firearms classification is not determined on its magazine capacity. It's a separate regulation that limits its capacity. I think its a good one for Ian Runkle to take a jab at and see what his legal opinion is.
 
Get an aluminum rod and rivet it to the end cap and be done with it. That is what I did with my M3K.

Mumbles, Runkle would tell you it's an interesting (expensive) thing to find out the hard way and suggest that you go experience it first hand.
