Actually like the 20 rounders for their light weight and handiness, but have a bunch of 30s as well.
Because of a well founded fear of aftermarket mags in general, I've stayed away from those.
Like to shoot my Scorp, but don't pound it as hard as some here.
Hate to burn the ammo.
Oddly, do have a 10 rounder for the Gen I Scorp, the .32 all steel gun.
