new here, hope for some help

[calibrator]

My $.02 is that it's a .30 cal Commercial. Pretty expensive to shoot, compared to the 9mm. It IS a Luger however. If ammo were plentiful, I'd rather shoot a .30 cal vs a 9mm for accuracy. They don't seem to hold their value as well as a 9mm variant. NOT an expert here, YMMV (Your Mileage May Vary).
