G23c issues

[Funeral-tripod]

Afternoon ladies and gents,

Wondering if somebody could help me?
My g23c ( not sure the brand) has developed a wee bit of an issue. I gassed it up today with predator ultra gas like normal but when I fired a shot the slide shot up off the lower.
Any ideas what could be the issue?

Kind regards

Wait the slide came off the gun with the mag in ? Get some photos up of the slide rails on the lower frame and the under side of the side its self

Yes indeed. Slide shot straight off with the mag still in. All gas vented out the top too. The slide no has a crack along the bottom where its attached to the lower, it wasnt there before hand. I imagine I'll need a new slide but don't want to invest in one of it's going to happen again regardless. I'll get some pics this evening. Cheers
