Haley Strategic SKIMMER trigger for Glocks in 9mm, except for single stack glocks it is a complete drop in system for a gen 4 and the rest you have to swap parts into the trigger housing. This trigger takes out all of the pre travel in a stock Glock trigger making it very close to a 1911 trigger. The Trigger pull weight is about 5.5lbs, but can be dropped to 4.5lbs if you use the stock springs instead of the one supplied. This trigger has been used less than 500 rounds. I am asking $50. I do not want any trades. Contact Joe by phone or text at 51zero-20zero-618zero for more information.
