Stick with glock oem parts, specifically the 3.5 minus connector. - Apex Tactical Specialties Glock Action Enhancement Trigger /Gen 3 Trigger Bar

This trigger after installation started out great, just as advertised. then after mabye 1000 pulls, it started changing feel, getting mushy and finally I realized that the . trigger break is all the way to the back of the frame and won't even break sometimes!

This hunk of junk sot me over $100 at an online Apex dealer. after looking online and comparing prices and descriptions of aftermarket triggers after it had become clear that the 4.5 lb. pull on my 17 was stopping me from getting tight groupings in my target practice. I wish I had run across the information about the Glock minus connector before I paid $100 for this utter garbage. But I didn't until after the apex went bad and THEN I found information in multiple places about the Glock minus connector and how all the aftermarket brands are inferior to it.
