Glock 19 TR-1 Upgrade Performance Trigger Review

Triggers are always touchy subjects, but I believe that reliable upgrades can yield a performance gain if the shooter is already at a skilled level. The TR-1 Performance trigger has run perfectly since it was installed and is definitely an upgrade over the standard Glock trigger.
