Well, Uzi bolts are made from sintered steel...

Yeah, it looks cheap. But I have an opinion on self-defense firearms.

Don't fall in love with them!

You are going to use them once, that is, to save your life or the lives of your family. Then the cops are going to take it. You might get it back, perhaps it's been disassembled and the parts tossed loosely into a box. And I've seen that happen to a LEO's 39 because in had a FTE on the last round during an exchange with a felon.

Do you care about the scratches on your snow shovel? Do you polish your electric can-opener? When was the last time you took your door-stop out for dinner?

While I do not have the casting mark like yours, I do think the fit and finish on mine is lacking. It feeds, fires and ejects with all three magazines. The factory replaced the laser. It (sort of) places all shots into center mass.

I care about it with the same pride of ownership I do a shoe horn. It functions, and that's enough.
