The most significant difference I can feel is the undercut on the trigger guard. Believe me, after testing aftermarket connectors against the newer version Glock “-” connector for the G42/43, the difference in trigger pull weight was not worth the cost of an aftermarket connector. If you’re disappointed in the trigger pull weight on your G42/43, I have the solution to your disappointment and it only cost $6.45! With adaptations, left-handed mag releases as well as ambidextrous mag releases have now been produced. Factory-installed magazine releases button are known to be difficult to operate. If you are looking for an upgrade from a stock AR-15 magazine release, the Magpul AR-15 Enhanced Magazine Release will be a great choice as it offers pretty much what you need from a magazine release. It is also one of the best magazine release upgrades that you can get for your AR-15. Overall, the I.T.T.S. boasts a stronger reset over other standard triggers, making it one of the best performing Glock triggers that you can find.
