Depends on the gun , and possibly how much you want to spend as far as time and money modifying every mag you ever want to use with that gun . And then you should consider any possible resale value . Some people might not want to buy a gun that ' s been modified like that , nor have to constantly mess around with mags that are also modified . <| sep |> We have one at our local food court in suburban Seattle WA . <| sep |> If that ' s true , I wonder if Michigan will deny it . Apparently the votes were recounted twice there because how close it was . <| sep |> Look at my example again , its obvious that shifting at peak torque doesnt make sense . You want to optimize torque out of the transmission , so staying in lower gear often maked sense untill the torque starts dropping so much that you get more by shifting up and dropping revs to higher torque .
