The base plate or floor plate looks pretty long. Is the metal body of the magazine truly 35 rounds and it just has a weird floor plate or is it actually a 30 round magazine with a plus 5 floor plate?

The reason why I ask is because if I'm going to have an extended magazine I want it to be a full length tube and not use an extended base plate for additional capacity.

For example on my glock factory stick mags I take the factory plus two off and just run them at 30. That's because the Glock factory base plate suck and I dropped one and the base plate came off and spewed ammo everywhere I'll never forget that.
