The stock trigger pin and trigger frame design makes it nearly impossible to eliminate all side-to-side play. The Era Paintball Designs trigger pin overcomes this challenge by placing two o-rings on both ends of the pin that act as stabilizers inside of the trigger frame, reducing nearly all side-to-side play in stock triggers for Promasters and Freestyles. The pin is amazingly easy to install and is a very inexpensive upgrade that will dramatically decrease side-to-side play.
The pin is sold by itself. If you buy the trigger the pin is included.
