While hunting, yes. Otherwise, no.
Remove the cap from the end of the tube and be careful of the spring which is under pressure. The plug will come out with the cap.
Easy, Unscrew the nut on the end of your gun, Remove the barrel/foregrip. You should now have just a magazine tube and the trigger/stock assembly. Take a screwdriver and slightly pry the rod out of the end of the magazine tube. (Mine just pulled out with my fiingers) nothing is holding it in. Reasemble without the limiting rod and Voila you now have a 4+1 capacity instead of 2+1
Best to ask a gunsmith for help.
You take it to a Volvo Dealer and they plug in a laptop and reprogram some parameters on the ECU in the truck.
If you are referring to the magazine tube plug. The answer would be No. It is put there for bird hunting regulations only.

Remove the 2 screws from the end or the mag tube and the cap and spring will come out. Do so carefully as the spring is compressed
most pump shot guns have a cap on the tube below the barrel, this must be screwed off to remove the plug, be careful game laws limit the number of shells allowed
the lower tube has a removable round nut, remove it slowly a spring will come out, the plug is at the bottom, turn over the shotgun and the plug will fall out. make sure of local game laws if your taking it into the woods. every place has laws and limits on the number of rounds a gun can carry
Remove the gas system. Drift out the black cross pin out of the magazine tube. The pin is directly below the gas system through a polymer plug. The polymer plug should come out of the top of the magazine tube when you remove that pin, so be VERY careful when removing the pin. Now remove the magazine spring. On the follower end of the spring should be the plug you are wanting to remove. Remove it from the spring. And put the spring and polymer plug back in. The dished end of the polymer plug goes toward the end of the magazine tube.
