Basic Glock Upgrades

First thing buy this book, it has a lot of good info and you will have a good starting point (you do not have to do the work yourself, but some thing are easily done by you):


“How to Customize Your Glock”
This will give you a great starting point. I have customized several of my Glocks.

The first thing I do is a .25 trigger job - polish all metal touching parts in the trigger group

Next, the addition of an Ameriglo Pro Glo Front sight that is designed to shine with a orange circle in the daylight and has a glowing green dot at night will help you keep your eye on the front sight, import in order to aim properly.
You can also consider changing the trigger spring to a NY#1 and a Glock OEM 3.5 connector, this changes the trigger pull and break point. I have found it to my liking and it gives ME better control.

These are the things that I have done that are Glock concentric.
You can also change barrels, add magazine well, add laser, change rear sight to metal adjustable, plug hollow on back-strap of grip, have grip angle changed by gunsmith, change pistol color, change out lower frame for a metal one, and the list goes on. This is the most customizable handgun after the 1911.
