Jai - the basic changes to the Gen 5 versus previous generations are: Upgraded barrel design for increased accuracy; Improved aesthetics for slide and barrel; No more finger grooves; Ambidextrous design for slide stop lever; Enlarged magazine well. The gen 5s come with three magazines (15 round mags in this case). The aftermarket possibilities for Glock sights are almost endless. I recommend you start looking at Dawsonprecision.com.
