I have P 320 XCarry (engraved on slide XCarry) , I have grey ghost treaded barrel which I want to install on that slide. does anyone know is it only required hood fiting or …. breafcase is 0.395 and barrel hood is 0.404

I m new with Glock platform , just want to see around what’s parts are good. my gen 3 frame is without locking block

Any advice what locking block is “best on market” I wish to try Lone Wolf but everywhere is out of stock
