First off I want to say it’s hard to trouble shoot technical or mechanical problems over the internet regardless of if ithas to do with guns, cars, computers or pretty much anything where unless you are there in person it’s really hard to figure out the problem.
But I will attempt to address some of the more common issues why a blank gun may not be functioning properly.
Why is my Semi Auto Blank Gun Not Cycling or Ejecting Shells?
One very common reason a blank gun may not be cycling the shells properly is because the owner has removed the barrel restrictor plug. People usually do this to make the barrel opening look more realistic but the barrel restrictor is a necessary component to increase the back pressure allowing the slide to cycle fully to the rear position so it can eject and pickup a new shell.
The blanks you are using may not have enough gun powder in them. Some blank guns require banks with more gun powder than others, again this additional internal pressure forces the slide all the way back, if the blank does not have enough gun powder in it then only a partial slide motion happens and so the discharged shell may not eject properly, in this case the user would have to clear the blank gun manually so another shell can then be picked up and loaded into the breach.
If your blank guns is dirty or not lubricated then it may act sluggish again restricting the full movement of the slide which will effect correct operation. Make sure to thoroughly clean and lubricate your blank gun, that may be a quick fix for you!
You may have a faulty extractor? The extractor is like a hook that grabs the discharged shell while the slide is in the reward position pulling or extracting the shell out of the breach. If the extractor is worn or broken then the empty shell will not be ejected from the breach so when a new shell is picked up from the magazine it has nowhere to go and usually you will get a jam-up in the ejection port area.
One final situation that can cause your blank gun to not cycle properly is to strong of a slide spring, some blank guns out of the box just come with a really heavy slide spring, so much so that even blanks with lots of gunpowder in them are still not strong enough to make the slide operate full motion. Your only option here would be to replace the heavy slide spring with a lighter one.
