Thanks for the info on the serpa, would you recommend removing / disabling the lock mech all together?
I am forced to use one as a duty holster for uniform work. For plainclothes or on my own time, I would simply choose another holster. Just watch a few minutes of various videos of guys unable to get their sidearms out of their serpa holsters and it might leave an impression.
People do not think about it, but a lot of fights go to the ground. If you are rolling with someone, there is a good chance for debris to find its way into your rig.
Just something to consider.
