unless you have the right equipment, its not a matter of when you get Injured (I dont mean just hurt), its when.

the problem with catchers chest protector is you dont have the collar bone/shoulder protection, let alone chest plate... essentially its inadequate.

Plate shoes are a most at just about any level of ball worth discussing.

Talk with people in your area, theres always equipment floating around or theres always ebay.

your mask and shin guards are probably fine for now.

good luck
