Once you've got glock triggers "figured out", there is little to replace other than springs. Ramping the plunger and polishing the connector parts does the job quite well. I fear lawyers after the shot, so I stick with all factory internals on carry guns. Match pistols are never used for carry.
One thing I don't see people talk about is what happens when a raindrop or a little mist lands on that red dot sight. Makes it hard to acquire a target through the Lazerium on the HUD. Just sayin. Also, people in competition draw from the holster into the same stance over and over until it is muscle memory. That makes it easy to acquire the dot, but what happens when you draw into a weaver stance instead, or draw out the driver's window and have to maneuver around the pillars- you'll never find your dot. It's okay, the bad guys will wait if this happens.
So be careful out there with your modded triggers and red dots with concealed carry. If you survive the incident, try to survive the courtroom, too.
I hear that! I'll usually carry a DA in the same type holster I posted but when at the range or outdoors that Fulcrum trigger is the shizzznit Son!!!
