It appears that the PST has Ameriglo Cap night sights rather than the standard Glock sights.

What is the difference between a Glock 23 PST and a normal Glock 23? I'm looking to buy one online
and all it say is Glock 23 40 S&W PST. Is it the same as a Gen 3?
@SouthernBoy you sure its a gen 4? the grips
look like its a gen 3
So I must retract my statement and apologize for my error.
