I'm too lazy to look it up right now, and sleepy, so I'll just ask.
1) Does it have the half cock safety? Judging from the scratch in the side of the mag
I assume it has a mag safety.
2) Do the mags have the spacer, or is the spacer in the mag well.
3) Is the recoil spring captive ( I know it has no recoil spring plug).
edited to add... 4) Why is the sky blue? (sorry, couldn't resist. After rereading my post
it seemed a little "off".
