People should buy, use, and do whatever they want to their property, but just be aware that any trigger that has to modify the vertical extension like this:
Attachment 35430
reduces pre-travel so much that the amount of "engagement" between the trigger bar cruciform and trigger mechanism housing "shelf" (i.e., the so-called drop safety) has been reduced by about 80% compared to OEM. If that's what you are looking for in a Glock trigger, then this is for you. BTW, that mod to the trigger bar vertical extension is necessary on their trigger because it if wasn't done the firing pin safety would be deactivated when the trigger is fully forward and at rest.
I'm not trying to denigrate their products. Just providing info -- info I spend about 20 hours a week explaining to people at my other job as I attempt to talk them out of being a customer.
Personally, I would not consider using a aftermarket trigger that needs to modify the trigger bar to maintain any of the standard Glock safety mechanisms. But I'm just some dude on the internet with an opinion and approximately 0 followers on social media. My opinion is worth exactly what you paid for it.
