If you won't own a gun without 2nd strike capability then you are eliminating the majority of modern automatic pistols including Glocks and the much loved 1911 (not so modern). In my experience it is rare for a centerfire cartridge to fail and when it does it is just as likely the firearm and not the ammo. Yes, it can happen but like I said it's rare. This has been my experience and maybe not yours. Years of hand loading and I have yet to see a significant difference among primers for standard ammo when considering light strikes. We are talking about light strikes, yes? Reliable feed and eject is far more important to me as that is where most problems occur. The "bang" part is statistically the most reliable part of the operation.

I'm not interested in telling others what to own and shoot but 2nd strike capability is not even close to a deal breaker for me. YMMV.
