Recently had a Scherer connector installed on my Glock 19 for improving the factory trigger from 5lb (or greater) down to 3.5 lb. At first I expressed some doubt as to the level of improvement, but after a range test recently, there is a noticeable difference and improvement in the trigger. I have not had the new trigger pull measured, but it is perceptibly lower and crisper than before. As Glock experts say, a match trigger it ain't, but it was well worth the $30 total cost for the job.
