Yeah, really. I was going to mention the LCP too. I love the Colt Mustang. Great design.
my mustang is from the 90s and even then they cheaped out by putting a plastic trigger and guide rod. around 5 years ago it started have jam problems, I took it apart and found the trigger has a thin steel rod going from it to the sear. the hole in the trigger that actuates the rod was elongated and almost torn through....I went on line and bought an aftermarket aluminum trigger and rod. no problems since then.
I do believe that plastic guns and parts are fine if you don’t care to practice a lot....I tend to shoot hundreds of round through any gun I bring to the range. had I just kept it loaded in my pocket for protection, it would still be working today with its original parts...
