Looking at 2 different triger kits... 1. Vanek Classic Trigger Kit 2. Glockworx Zev Tech Complete Drop in Trigger Kit Would like opinions of folks who use one or the other...preferably who have used both. This will be for a competition gun only (not SD)...G17 for IDPA SSP. Thanks in advance for your input. Wanna kill these ads? We can help!
