GBB wont lock back

[RATCHET]

Recently I was playing a game and I pulled out my kjw kp-05 and fired the whole clip but it kept firing till the gas emptied after all bb's had already been fired.
So what I'm saying is the gun should lock back when the last bb is fired but it wont. What can I do to fix this?Thanks in advance.

Do this for us. Take your empty (no BBs) pistol mag and put it in your pistol. Pull the slide all the way back, hold it there for a second, and then let go. Does it lock?

Probably too much cooldown after you fired a whole mag off. Take a freshly charged mag with no bb's and fire one shot. It should lock back.

It doesnt really lock back it "sticks" instead. I understand the slide lock tab should move in place but it doesnt.

Most likely just cooldown or low gas after a whole mag. Many GBBs will not lock back after rapidly firing a whole mag. Just a limitation of using propane.
