Upgrading a Glock 19 with aftermarket steel parts
 

I plan to upgrade my we g19 with steel parts ,Is this legal to import a cnc steel slide/barrel for my we g19? And i only found slides mounted on g3' s (mine is gen 4) will it work ? I have for almost 500$ in parts ready to order but i want to be sure that everything will fit.. thanks people

EDIT

Im sorry , i posted this thread in the wrong section and idk how to fix it (help adminsss)

Legal to import uppers/slides, not lowers/frames.

Gen 3 should work on Gen 4, may require modification though. All slides/kits are not usually a 100% drop in fit anyways.

Thank you for the fast reply , gunsmithing is how i win my life so fitting is not a problem , since its legal to order my parts i guess i can go wiithout trouble :)

You want to make sure you can dial on the gas; otherwise a steel slide won't cycle reliably.
