i love my 3rd and 4th Gen Glocks. i have a 3rd gen 19 *my picture* and a 4th Gen 23. in .40S&W.
the 4th gens recoil spring is much heavier, which i have seen makes the recoil of the 23 feel like the 19.
however the finish on the barrel wears just as fast as the 3rd gen.
the mag release IS reversable , you can use left or right easily.
same takedown, same stock U sights *unless you pay more for adjustable or night*
whatever you do dont get the M model though. *even though glock said they were discontinueing it*. the grip is not blocked it is tiny burrs and will rip up your holster/shirt on your carry side.
few improvements, still same glock
best thing to do is go to a local range and rent one. the recoil on the 19 is cake.but try one out. if ya like it, its deffinately worth the $563 at cabella's!!!!
edit* on a side note, for a few hundo extra, if you get the mode 23. you can get a 19 barrel, slide and mag , and turn it into a 19 for cheaper shooting, then swap back to a .40 cal for carry ;-)
