2nd gen 19.I don't like the finger grooves and don't use lights or lasers so I don't have any use for rails.
The whole kaBoom thing is incredibly,incredibly overblown,no pun intended.My 19 has digested well over 20k rounds since 1991 and still runs liks a top.It might look like 4 shades of ass but it's a stellar pistol.
I also have a G22 with 9mm and .357 SIG barrels.I actually shoot the mid-sized Glocks better than the full sized ones as I much prefer their grip and I could give a flip less about giving up a couple rounds.If I could keep only a single pistol,God forbid,it'd be the 19.
