- Many holsters made of rigid polymers - Kydex or injection-molded - use screws as part of the design. In some cases screws
are used to mount the "pouch" to some sort of belt loops or paddle. In some cases they are used to adjust the tension
of the pouch on the gun, by means of compressing a rubber washer or grommet.
- In either case, the screws can loosen, with the potential for the holstered gun to fall from the point of carry or for
the gun to fall from the holster, if no other retention feature is present. Such screws, on a holster that is worn
regularly, need to be checked at least once a week. Further, once the adjustment is established, it may be wise to
secure them with the appropriate grade of Loctite adhesive or a dab of nail polish. Either one is applied to the
threads once they have been degreased with an appropriate solvent, such as acetone.
- Some leather gear also makes use of screws, typically for tension adjustment. Many years ago I had an embarrassing
incident when a loaded magazine clattered to the tiled floor of a public restroom from a double magazine pouch fitted
with tension-adjustment screws. I had failed to check the tension when I switched the pouch from carrying .45-caliber
magazines to 9mm magazines.
