Security job physical requirements ?

Can I get a job as a security guard ? I have a year off college and I like working nights.

I'm 5'6, 130lbs, 19 years old, shoulder length hair.

I think if I was an employer I'd never employ someone with those stats, but just wondering anyway.

Going to get an armed license hopfeully, I'm a good shot.

The hair might be a problem, depending on the Guard company and who they are assigned to. You also, in most cases, will require a Guard Card

it would be better if you are taller, shorter hair, well built, martial arts and fire arm knowledge....
