Looking for some opinions on this handgun. A few bullet points: - how do the plastic mags hold up? - My personal point of reference would be the Glock 17 and Sig 226, so I'm wondering how it compares in terms of ergonomics and stopping power with the civil-spec round. I'm not going to automatically buy the "hurr-durr most powerful," just wondering if the stopping power is adequate for self-defense. I also heard the ammo's pretty expensive, though I know it also comes in .22LR (though the pistol itself'll still be expensive just for plinking). - Any reliability issues with the weapon?
