Collectors:
Many collectors want to own guns but for reasons like gun restrictions in their area, they may not be able to own a real gun or certain types of real guns. Blank Guns can offer a person with heavy gun restrictions in their area the ability to own similar Blank Gun versions. Perhaps they can own real guns but just simply don’t want to go through the licensing and registration hassle of owning a real gun. Blank Guns can generally be purchased for far less money than a real gun which is appealing to collectors who in many cases may not even shoot them.
Celebration:
In places like Turkey, people celebrate holidays and events by shooting Blank Guns into the air, at one time they actually shoot real guns, but people where getting injured or even killed by the falling bullets. Because of this, Blank Gun production became an industry in places like Turkey as Blank Gun manufacturers like EKOL, Retay and Zoraki (also know as ATAK Arms) are Turkish companies.
So now you know some of the reasons why a person would want to own a Blank Gun. I have Blank Guns and I also own real guns too. One reason is because there are many Blank Guns I own that I can not own in their real steel versions because of Canadian gun restrictions so obtaining a similar version in a Blank Gun allows me to own these models.
If a Blank Gun is not for you, then by all means get a real gun, but please understand that there is a place for Blank Guns, and in those environments, a Blank Gun is actually a better choice than a real gun.
