Guns you want to see made.

You should consider some slight modifications. Move the magazine further back. The PPSh's magazine is forward more because it is open bolt. This gun looks closed bolt. Plus if you want a good plinker, open bolt is going to make accuracy as joke.

In my opinion, just buy a Ruger 10/22, buy a 50 round magazine or drum, add a peep sight and you've got a cheap plinker, very similair to this gun. Except it doesn't fire crap ammo, .22s are cheaper than dirt (I never got that expression, dirt's pretty expensive anymore)
