I do! I do!
Steel guns specifically.
Only a single ratty Kel Tec P3AT serves as an example of the plastic tribe here.
I'm not even too keen on the aluminum alloy in the frame of the Smith & Wesson Model 642, the upper and the lower of the Colt AR15, and the trigger guard of the Ruger 77V and those are the only firearms around here featuring aluminum alloy components.
I think it's the result of an allergy to plastic and aluminum.
