My S&W SD9VE with an Apex SD Trigger and Tactical Spring Set > your Glock... For a lot less...the trigger in this SD9VE runs circles around the Glock trigger now...$.25 Trigger Job included! I polished a few contact points...had to do some minor fitting and the result is about a 5.5 to 6.lb trigger that is simply amazing with less travel, a more audible and tactile reset, and almost no stacking at all - very smooth. Very clean break. It out Glocks the Glock! I have had many Glocks and played with every combination of polish, connector, and spring sets you could imagine. The S&W is "winner winner Chicken dinner"! I did have to remove about .75mm of material on the rear of the trigger to get everything to work properly...look up the install and you;ll see what I mean. This kit is worth it. The only pain of the entire install was the trigger pin...OMFG...lining up the trigger, trigger return spring, locking block, and slide lock to push the pin through is tough even with the supplied slave pin.
