A friend of mine trains PD's and federal agents all over and thus has quite a bit of experience. I would definitely call him an expert. He tells me that Para's internals are week and has seen things like the safetys pop out on them multiple times. As a plinking gun I'm sure it's fine for the right price, but I wouldn't use one for protection.
I have a P14 that I shoot in competition for 10 year and never had a issue with it. I also have a Warthog and love it.
