For sale is a used Glock Performnace trigger.  It works in both Gen 4 and Gen 5 Glocks.  (Doesn't fit single stack or 45acp models).  The trigger has been cleaned and freshly lubed by a certified Glock Armorer, and it is ready to drop in.  There are no issues with it.  I just sold the gun that it was installed in, and the purchaser wanted the stock trigger instead
