I haven't yet seen a KJW P14.45 in person, but I has WA's version for a while before I sold it off to build my AR15. A quality piece of work, but for some reason I wasn't as impressed with it as I was with the old SVI 5" standard I had before it. Sure wish I could find another one of those.
@Rick,
Safety's easy to pop off if you know how. Back when I had my WA SVI, I was being an idiot and twirling it around (back a few years, before I learned a few things). Lost my grip, and it hit the arm on my desk chair, with the result being a safety (both sides) that popped off. It's fairly easy to reinsert, but they CAN fall out.
My suggestion? Learn to bench strip the gun. I took my SVI down to the last screw once every other month if I was using it often, about ever 3 months if I wasn't, and sometimes I'd clean it just for fun. You'll learn how the thing works, and you can replace any parts that you may need to get to. That, and with it being cleaned and lubed with fresh, clean grease, it will perform better for a longer period of time.
