The G22 gen 4 is a really great piece. But forget about getting it a 9x19mm barrel later...get a .357 SIG barrel (G31). I like my G31 gen 4 than any other Glock or any other defense handgun I've ever owned (more than 30 in 25 years). It's almost like having a hand rifle. :-)
Plus, there's not as much demand for .357 SIG ammo, so it's often available in places where the more common (but lower performance) calibers have been depleted by panic buying...though it'll never be cheap.
