4. Hunchback Stride
When trying to conceal a shotgun, rifle or submachine gun under a coat while walking, the butt of the weapon will often cause a noticeable bulge behind the armpit. Additionally, the jacket does not move naturally because it is supported by the outline of the weapon. Also, when someone wears a shoulder holster or straps on a sawed-off rifle, shotgun or submachine gun under his or her arm, a bulge in front of or behind the armpit will often be visible.
