U said your 4 year old checks every gun before he shoots. That means there are multiple guns he is fireing. Come on now. I grew up in the country and my dad was a hunter and tought me gun salty. But I didn’t shoot a gun even a bb gun untilled I was prolly 6 my father bought me a 10 gauge when I was 8. But 4 is a little early to handle guns he doesn’t have to PLAY with guns when he. Is 4. Its kids like that who shoot other kids saying. Its OK I can show u my gun my dad lets me use them all the time. Come on guy use your brain!!!
