How well does the holster contain the gun?

0 = Open carry using a nylon one-size-fits-all holster with no retention and a cheap metal belt clip.
5 = One retention method and two of the three of: a cover garment, good construction or good mounting.
10 = Strong construction, secure mount to the belt, 1 passive and 2 active retention methods, plus a cover garment.

This rating is a measure of two things:

1. how well the holster prevents your gun from falling out when you’re wrestling with a bad guy (or crashing a motorcycle).

2. how well the holster prevents a bad guy from getting your gun.
