Stop in for a cup of coffee

The glock is a handgun and the .22 is a rifle.

I think they are similar in caliber size but it's my first handgun so it is very different experience.

I have a cop friend so she is showing me how to handle it and i got to fire it at the cop range.

Kinda scary, my heart was beating fast but it's a rush to fire it.
Uh no. A 9mm is much bigger than a .22. Diameter wise, a 9 mm bullet is .358 inches. A .22 is actually .224 inches in diameter but has a third of the powder behind it as a 9mm.

That said, a 9 mm is very easy to shoot. Rookie friendly. You'll be fine
