Specifically the difference between a Glock 19 and a 34, assume the same sights for each.
This for a police patrol duty weapon. Current setup is a Gen4 19 with the orange Trijicon HDs. I am considering the Dawson fiber optic front(.100-.110).
Is there a practical increase in precision? Or is this P.I.I.?
BTW, I have 56 year old eyes and my new glasses let me see my front sight very clearly, for the first time in several years.
Not looking for an excuse to buy a new gun, I've been buying ammo and shooting instead.
