Ruined, or Improved?
I just watched Guns & Ammo tv do a demonstration at the Ruger assembly plant. They dropped a 4.5 pound weight about 3' onto an old aluminum 10/22 trigger guard and cracked it at the thinnest point of the hoop that would go around you finger. They then dropped the weight on a new polymer guard and it bounced back into shape.
I'm thinking the things the consumer will be looking at would be.
Plastic is more impact resistant.
Plastic will be more likely to warp, & change size from temperature. Resulting in possible bind, change in trigger pull characteristics, FTF.
Plastic looks & feels far, far, far, far, far, far, far, far, far cheaper, worse. (opinion)
So following Remington's foot steps with plastic housing a good move for Ruger?
