Makarov round stuck in Glock 17

I know this sounds stupid but my friend managed to mix makarov rounds with lugger 9mm. He loaded my glock 17 with makarov rounds and tried to shoot it.
I had three guns at the range glock 17, radom p-64 and CZ-82.
So, the result - I have makarov round stuck in a slide(I can see it through extractor port) but I cant take the slide off because it stuck. I tried everything but the slide doesn't come off. Should i take it to the gunsmith(recommendations?).
I learned my lesson I will never let my frieds to play with my guns.[Bang]

Have someone put rearward tension on the slide, while gripping the gun, CAREFULLY, , and without placing yourself if front of the gun, try to gently tap it out from the muzzle, with a plastic punch of some sort. If it won't come loose with light taps, and I stress LIGHT, take it to a gunsmith. Better safe than sorry. Whatever you do, don't even think about trying to shoot it out.

I would gunsmith this one.

you have this:

wrong round.
round in chamber.
slide that won't move.


you want to push it back out through the muzzle: this means some part of you will be placed in front of that muzzle, a tool will be placed down the barrel and tapped. don't forget it is a live round. that round could go off, simultaneously blowing the gun to pieces, you to pieces and you lose it all.

think about that. I know you will do the right thing!

Thanks guys, I fixed the problem using the method provided bu Butch from Glock forums

I'm thinking the slide is mostly closed on the round, which is stuck in the chamber....

If that's what you have going, try this:

Be SURE to keep it pointed in a safe direction,

get down close to the ground/floor (in case you knock the gun out of your hand),

With the gun in your shooting hand, grab the rear of the slide with your other hand like you're going to rack the slide (palm on one side and all four fingers on the other),

Holding the slide very tightly, gently hit the grip with your shooting hand trying to push the grip forward and hold the slide still. Don't hit the trigger!

Increase the force of the blows a little at a time until the round is ejected.

This will either eject the round (I've never had this not work), rip the rim off the chambered round, or break the extractor (I've never had either of the last two happen)."[Beer]
