I’ve noticed this problem quite a few times. The stechkin pistol normally is just a vest pistol, it fits fine inside a jumpsuit pocket. The suppressed stechkin is almost twice as long and shouldn’t fit in your pocket, right?
well if you already have the stechkin in your pocket and you put the suppressor on it, it allows you to magically store this long pistol in your pocket no problems once so ever.
hence, a bluespace portal should not open in your jumpsuit pocket assisting you in hiding your assassin handgun. When putting the suppressor on your gun it should just immediately fall out of your pocket no questions asked.
