From what I've seen so far, plastic trigger guards seem to be doing well in service. From all accounts, they're proving to be durable enough for the average user, and have the advantages of being non-rusting and needing no lubrication.
Doing some research, I came across this from MIL-S-3443E (20 March 1989), which is the military specification for a 12 gauge riot-type shotgun. Mossberg advertises their M590 series as meeting all the requirements herein:
"The trigger guard shall be of metal or suitable glass fiber-filled Nylon plastic construction and shall have sufficient strength to prevent manual deflection of the bow (causing actuation of the trigger mechanism) or permanent deflection of the bow."
A later iteration of this document (MIL-S-3443G, dated 4 October 1993) changes this thusly:
" The trigger guard shall be of metal construction and have sufficient strength to prevent...."(all subsequent text is identical)
So it appears that, for whatever reason, plastic was dropped as an authorized material for trigger guards for military applications. Have these particular assemblies since been improved or is military service just too rough for plastic trigger guards?
