[Ratters]

Make sure you cock it, lock it on the slide catch, pull the takedown firmly on both sides all the way down and hold it down, release the slide and in a forward sweeping motion with your other hand push it forwards and whisper "gtf off b!?ch"

VFC Glocks can be picky this way too, show it who's boss, all else fails, swear at it profusely and give it the finger, calm yourself and try again

Hope it works
