I like it very much. It is an extra safety that you can activate any time you like . All that other BS that you read about it , it is just that : BS. It is perfectly safe to push the trigger sideways to on and off . I have the NY-1 trigger on my G30SF and combined with the Siderlock it is perfect. I will install those two options on all my future Glocks . Absolutely the best way to incorporate a safety system on your Glock without modifications and very easy to do.
