Looking to buy a semi auto 9mm, even though I don't really need one. Just want something to run the hell out of while shooting as cheaply as possible. So it got me thinking, what are some characteristics of a pistol that would make it conducive to running the cheapest stuff. Barrel/slide length, heavy vs a lighter slide, hammer or striker, polygonal or traditional rifling and so on. If a pistol was being made from the ground up to run the cheap stuff specifically, what would it look like and what's out there already that comes the closest to that? I don't know the ins and outs of pistols to have much of an idea, that's why I'm asking you guys. The only thing I can think of is maybe a longer barrel at least 4" might be good to keep flash down since cheap ammo doesn't use any kind of flash suppressant powder. Let me know what you think, thanks.
