You have a nice collection.
1. Glock 19, compact enough for CCW, big enough for the range,a little cheaper to shoot than your G22.
2. Didn't see a .357 in your collection, $500 will buy a new GP100 or used S&W 686.
3. Ruger or Browning .22 target pistol for range time fun.
4. Glock 23 or 27 to complement your G22.
