I'll explain what I meant by writing that. Of all the shooters I have seen in my life, I have never seen one that had a 100% reliable Tanfoglio (especially in .40).
True, it is mostly mag and ammo related in the sense that you can adjust both mags and ammo to make the gun work better. But I prefer guns that aren't as picky with ammo or that come with mags that work.
And yes, of course, every type of gun can jam. But you have to try harder to make that happen when you're shooting a Glock
