Hi Vega!
It is the reverse, my 14 yrs daughter like to smell my .45 muzzle after the firing.
You give me idea for the .22 for ages like that. I think the .45 has too much recoil for my daugther to practice.
My little boy is still 8 yrs old so I cannot let him shoot yet with real gun.
One solution for the smell, have them spray with strong perfumes.
Thanks
