Glock 17l!
if you buy the GLOCK 34, after a few months you will wish you had the bigger, better, cooler, more rare GLOCK 17-------LONGSLIDE! i have a Glock 17, and sometimes wish i had a GLOCK 17L, just because it would be more accurate, it would have higher muzzle energy, it would have less recoil, it would have higher fps then my 4.49inch G17 barrel. if you sort of want it now, your really going to want i later, the GLOCK 34 was made for IDPA, if your not going to do that just get the GLOCK 17L, and have the most accurate GLOCK in the market!
