TpwUK, ahaha yes it is air gun let it be...))) Your fantasy have no limits...

But for them who are interesting it was real model of Russian Automatic Pistol - CEDR (https://en.wikipedia.org/wiki/PP-91_KEDR).
Do not how to say it in English but it was pared down (sawn striker) and can not be used for shooting. We used it as reference in some cases.
