I've got a Bicentennial Nylon 66...one of the older plastic firearms in existance...
ever seen what happens when someone uses the wrong cleaner on one??
Examples are all over the 'net for melted Nylon 66's, XD's and Glocks...
How about UV light & heat?? Also killers of plastic...best to avoid leaving one unattended in a car...
or avoid storing one near a window where it would receive direct sunlight...
like in a glass-front gun cabinet...
Will it last long enough to be handed down to my kids?? Hopefully.
My care for it is meticulous...no cleaners, only soap & water for the plastic body...
gloved dissassembly & reassembly, one drop of oil applied with a Qtip on all metal parts,
which are then wiped down with a cloth & air-dried prior to reassembly...
Its 41 years old now, less than half of its 10,729 contemporaries remain...
will it last another 39?? Only if kept out of the sun & well-maintained
How about my Star M205 Ultrastar? And my Glock 20sf??
Same thing there, if you want it to last, you have to be very specific about maintenance & care.
Of course, you have to do the same with metal guns, be specific about their maintenance and care...
that's why there's a fully working 1927 Marlin 37 in my safe...
she aint the prettiest girl at the dance, but she'll outshoot most newer .22lr's
I have no illusions about a plastic firearm making it to 100 years...it'd be a dang miracle.
