You left "I dont really like or dislike them" from the poll.
100% of the guns in my safe and the guns that go to the range are metal. I enjoy collecting them, shooting them, and owning them.
I carry poly guns 95% of the time because they are light, just as reliable, and a rust spot, scuff, or holster wear on them doesn't even irritate me. Yes, the triggers all suck for target practice, but on a pistol without a decent thumb safety I prefer a stiff trigger pull. Especially since I know how light an 8lb trigger feels in stressful situations. In contrast, trying to make a striker pistol into a light-trigger target gun for range use to me is like taking your pickup to the track. Sure, you can mod it to make it something it isn't designed to be, but it compromises it's ability to do its intended task.
I expect the metal guns to outlive me and still look as good as when I bought them. If the plastics get too roughed up, I will buy another one. They are disposable. Better yet, I'll pass them on to a new shooter and recycle that plastic.
