There are many areas of this industry where it is all about preference and it’s not really a problem using holster A, holster B or holster C in a situation.   I realize that not everyone is going to be handcuffing a suspect and needs to worry about a bad guy grabbing his gun while stopping someone during a frisk, but there is more than that reason to have a locking holster of some sort.   There are plenty of youtube videos out there showing you the difference between the level 2 and level 3 holsters from Blackhawk and Safariland land and every one of them is for a different level of Law Enforcement or tactical applications.   Retention holsters like the Blackhawk Serpa are now military issued because in the middle of combat things can and will go flying if they are not locked down.

I know the Blackhawk Serpa holsters advertise that they are for concealment but I really have to put my foot down and suggest to any civilian that is carrying a firearm, that these are not the best holsters for hiding under a garment.  I personally suggest that the Blackhawk Serpa holsters be used for open carry or law enforcement because going under cover means the concern of snagging, and putting in another potential slow down like a locking holster in the mix is more of a liability.  There are plenty of holsters from Desantis or from Safariland that give you some level of retention that can be adjusted with a screw that don’t need to have a button release to get them out.
