Duo Slide Will Not Come Off

[Investment Janitor]

I have a 1944 Duo and I cannot get the slide to come off, I am cocking the gun, pulling the trigger, removing the magazine etc. turning the barrel a quarter turn and releasing the safety. The slide moves slightly forward and gets stuck on something. Can't figure it out! I have numerous mouse guns and this one is the only one that has me scratching my head. Anyone out there have an idea? The pistol appears unfired.  Thank you very much! Regards, Rob

I pulled out my 1949 chromed Duo and field stripped it to see if I could determine what would be keeping the slide from coming off.

The only thing I can think of is that the barrel is not full rotated out of the channels.

After you rotate the barrel, see if you can pull the barrel forward.  Mine goes about a quarter-of-an-inch.
Being able to do that shows that the barrel is free from the channels and the slide should then be able to be removed.

Side note...after not having used my Duo or Z for a few years, I had a bit of a hard time getting it back together.
I finally remembered there is an extra step after starting to get the slide re-engaged...you have to flip the gun back up in the vertical (being careful not to let the barrel go too far forward!) to get the recoil spring and guide rods to fall back into the indentation in the frame.

Please let us know if this solves your problem.

Thank you. Not an issue with the barrel. I have other mouse guns that field strip the same way. Perhaps it has something to do with the hammer? I don't know much about these, but will continue to mess around with it. Appreciate your thoughts, best, Rob

Have you fully rotated the barrel?  It takes quite a bit of effort to hold the slide in exactly the right place to line up the grooves in the barrel with the grooves in the frame and if they aren't lined up just right, it will not turn.  If you can't easily twist the barrel, then it is still in the 'frame grooves' and you'll need to re-align and turn it some more.  It goes very easily when everything is exactly right, but it all has to be exact, and it isn't easy to hold the slide in the right place.

For reassembling, point the barrel upwards and make sure the recoil spring is aligned and then make sure that the firing pin is aligned, then line up the barrel and twist it back into place.

Thanks...that is not the problem, from what I can tell, something in the trigger mechanism or seer is not in the right position. When I release the safety, the slide comes forward about 3/8 of an inch and then stops. Maybe that is why the pistol is in 99% condition? It is a quagmire! Although the pistol functions as it should. Thanks again, best, Rob

When I disassemble: confirm clear, safety off, rack slide,  pull trigger, drop magazine, pull back slide and twist barrel.
Did you do anything differently?

No, that is the method that I follow, thanks!

Have you seen this U tube video on how to field strip a CZ DUO?

Check for a bulged barrel. I bought a cz70 once that had this issue

Thanks, barrel seems as new. I have seen the video. Let's just say I have never had an issue taking a gun apart. Next stop is to my gunsmith. Appreciate all of the advice! Best, Rob

Good luck! Please let us know what the issue was once you have it figured out.
