Please see the fit notes on our carriers and plates. Also, read your carrier’s manufacturer detail page. It should tell you which plates will fit into your carrier. Please email firstname.lastname@example.org if you are not sure.
If a steel plate has a build up coating on it, it will be longer and wider and thicker because of the coating. Sometimes this makes a tight fit into certain carriers. Also remember that a standard composite plate, Level III or Level IV, will be thicker than a light weight plate.
If you have a conceal carrier vest, it might have a plate pocket. The only plates you should put in there are thin plates and not steel plates. Steel plates are too heavy and will put too much stress on the fabric.
