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.
Why Are My Blanks Not Firing?
This is a situation where you pull the trigger and nothing happens. Lets get the obvious causes right out of the way here… Did you put blanks in your gun and are they new blanks? Did you chamber the first round in your semi auto pistol?
So now that that’s out of the way let’s look at some other reasons why your blank gun may not be firing a blank. Perhaps the firing pin is broken? Most blank guns are not made out of carbon steel and even the firing pins can be lesser quality than what you would find in a real gun so blank guns are more prone to breaking than real guns. I have seen broken firing pins in blank guns first hand so make sure to check the firing pin and that it is fully operational.
Try changing up your blanks to another brand? Again blank gun ammunition is not made to the same higher standards that real firearm ammo is made and some primers may require a little more pressure than your gun is providing. Even with real guns an ammo change may help the gun operate better.
Why is the Trigger or Hammer Not Operating Properly?
I have come across blank guns where there are mechanical problems in the trigger and hammer areas, you may be able to address this yourself but I would recommend taking your blank gun to a gunsmith since you will have to take the gun pretty much full apart to fix a problem in the trigger and hammer areas.
Of course make sure your gun is clean and lubricated, this can help a lot with the mechanical areas of your blank gun.
One problem I saw with a few EKOL Special 99’s was specifically with the single action potion of the trigger, when I would pull the hammer back it would not lock back and the hammer would often slip and fire randomly, this is rather dangerous. When I took the gun apart I found that the table top or step that the trigger was supposed to catch on was worn down on the edge so it would simply slip off. I was able to fix this by filing a new edge on the step area. Again this can happen because blank guns are not made out of as high quality metal materials as real guns.
Why does the Flame Come out the Top of My Blank Gun and Not the Front?
If you find that the flame or discharge comes out of the top of your blank gun and not the barrel, this usually does not mean anything is wrong with your blank gun. All it means is you own a top venting blank gun and not a front firing blank gun. In some countries front firing blank guns are not allowed but front venting blank guns are. The same may also be reversed in some countries, for instance here in Canada we can only import front firing blank guns with flare adaptors since our blank guns are imported under the assumption that they are to be used as signaling or flare devices.
Can I Convert my Top Venting Blank Gun into a Front Venting Blank Gun?
I really don't recommend altering a blank gun in any way as it may be a violation of your local laws and it could cause the blank gun to malfunction in a very bad way causing serious injury or even death!
In theory I suppose it may be possible to convert your Top Venting Blank Gun into a Front Venting Blank Gun but again you would need to allow for just the right amount of back pressure so a wide open barrel would not work unless it was a revolver. You can not simply remove the red plug and bingo you have a front firing blank gun because in most cases the barrel will be completely plugged in the frontal region. Not only would you need to drill out the plugged portion of the barrel but you would also have to somehow fill in the top venting area and again makes sure to allow for just enough back pressure to cycle the slide back and forth.
