Because we choose to race with guns. You wouldn't show up at the drag strip with your daily driver would you ? We don't show up to a match with stock guns. Take the paint off my Glock and it looks sick, but open it up and it sure isn't.
Ans that's cool and all. Drag race all ya want. but not everybody drag races with their guns. Just as you wouldn't carry a race gun for defense, you're not gonna carry a glock with a ny1 trigger into a match. When the subject of "rapid fire" got brought up, several immediately assumed competition. But op wasnt using a race gun, he was using a service weapon.
