Dear Corrado, 
 
I do not mind being in error, as I always wish to learn. 
After I posted my reply above, I noticed that your pistol was rifled all the way, and not merely made to take a key in the muzzle.  Please see my edited post above. 
It seems unusual to me, to not  have a barrel that unscrews, as the stock being made short, is Usually made this way so the barrel Can unscrew. 
I do not pretend to know more about your pistol than you do, but it Is most unusual! 
 
Thank you for correcting me! 
 
Very best wishes, 
Richard. 
 
Edited again to attach a photo of a little pistol I have, with stock very similar to yours, and the tab for unscrewing the barrel to load. 
This is how  I Presumed  your pistol was meant to work.  Thank you again for putting me right!
