Personally, I think its a sin to carry any good revolver...especially a S&W or a Colt in a kydex holster....
The only thing I carry any of my guns in ---is good, well made, horsehide leather from Kramer Leather !
I've seen a number of kydex holsters break during a variety of class/range practice/ rivets failing ??...maybe they weren't properly made, I don't know ....I just can't go down the path of kydex holsters...sorry.
A good well made leather holster isn't cheap ...and I'm not a competitive shooter, where it may be an advantage --but I'm not getting away from horsehide.
