Glock triggers are easy and highly subject to modifications. If you are of a mind to do any of this, I suggest you first get use to your gun and then take a decision as to whether or not you are going to make any mods. The factors involved in this decision are going to be if this is a range gun, a defensive arm, or both. Add to these your specific preferences and what you find works best for you.
In the final seconds of your life, just before your killer is about to dispatch you to that great eternal darkness, what would you rather have in your hand? A cell phone or a gun?
