there doesn't seem to be that much information out there on the trinity roller bearing trigger. being the only after market trigger currently on the market for the vibe I decided to type up a little review on it. sorry for the bad pictures but my camera didn't want to focus on the little objects.
PROS: I like the shape of the trinity trigger. the little S shaped lower bump of the trinity felt good on the fingers. also the roller bearing made the trigger feel more responsive on the gun. I also liked the option of being able to unscrew the magnet to adjust the pull strength of the trigger.
CONS: there isn't a back travel adjustment screw on the trinity like there is on the stock trigger. so after you pull your shot the trigger travels back until it bottoms out on the switch housing on the board. with the stock trigger you can back out the screw in the trigger so it stops on the frame just a hair after tripping the switch. for this reason alone i did not like the trinity trigger. the roller bearing is only on one side of the trinity, installed I think the trinity has more side to side slop then the stock one. I also didn't like the metal on metal click the trinity has compared to the silent operation of the stock trigger.
In conclusion I would have to say the stock trigger on the vibe is better then the trinity trigger. until a company comes out with a trigger for the vibe that has the back travel adjustment screw like the stock one I would recommend spending your money on other upgrades.
Anyone else buy the trinity trigger and come to the same or different conclusion?
