Yes, and yes.
There used to be a time when I shunned plastic guns and made the usual "have no soul" type comments. I was into 1911's and SIG P series (Still have the 1911's). I now own 7 Polymer pistols (2 PPQ-9s, 2 M&P-9 5" Pros, PPS, H&K VP9, H&K 45T)
After a few classes and shooting more defensive pistol type shooting I now appreciate them for what they are; reliable tools, lightweight, with good capacity. To be honest IF "the Walking Dead" erupted tomorrow, my 2K Les Baers are staying in the safe and I'll be carrying either one of my Walther PPQs or my H&K VP9.
