Would any policemen today feel better armed with a .357 Magnum over say a 9mm or a Glock .40 high capacity gun?
The .357 Magnum used to be favored for some because it was a much more powerful load than the standard service arm (back then a .38 Special)...it still is! What it lacks in capacity it more than makes up for in literal firepower (adding penetration abilities and "stopping power")...even rated against the .357 Sig it oversteps it especially with heavier loads in 158-200 gr.
On the side, a 4-6 inch barreled N frame, L or even K frame .357 Magnum with a half or full underlug looks mighty intimidating compared to a little glock box
