is this caliber going to go mainstream? why is it so uncommon? how is it different from others meaning what can it do that others can't? thanks
Define "mainstream".breakthrough said:is this caliber going to go mainstream?
It does little that 9mm Luger won't do, while typically giving up 2-4 rounds of capacity in an automatic pistol, and simultaneously falling short of true .357 Magnum power levels with heavier bullets and longer barrels.breakthrough said:why is it so uncommon?
It's better at penetrating steel car bodies and auto glass than other auto-pistol cartridges that fit within a standard medium-size pistol frame using a 10+ round capacity double-stack magazine. This is the reason why most agencies to adopt it have been state police forces responsible for highway patrol.breakthrough said:how is it different from others meaning what can it do that others can't?
With 2 important caveats: (a) using 125 grain or lighter bullets and (b) a 4" or shorter barrel. It's can't perform like .357 Magnum out of a 6" or longer barrel, and the .357 Sig case is physically too small to safely handle ~130gr or larger bullets unless it's downloaded somewhat.old bear said:[It] was developed to create a 9 M/M round that preformed like a .357 Magnum round.
There is 9mm +P so what's the point?

Its basically just a tad hotter than 9mm +P+. Maybe about 100fps or so. Nothing really monumental or spectacular.But make no mistake: 357 Sig is a good deal more potent than 9mm +P.

And that 150 fps extra (or more!) actually makes a lot more energy (energy is mass times velocity squared.) That means faster expansion, larger crush cavity, and more bone fragment thrown out.
