Stop in for a cup of coffee

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

I think the .22 has more kick but it be the difference in experience.

I am not really one who knows guns real good, in fact i never used to like them but now i work around a lot of law enforcement so they are rubbing off on me
