Glock 23 has jerky trigger

[daveshrews]

I have a 2nd gen Glock 23 that I installed a Scherer 3.5 lbs connector in quite a few years ago. The trigger always felt great until about a year or so ago. I began to notice that when dry firing the pistol, even with a firm grip and proper trigger technique, the pistol has a tendency to pull sharply to the left when the trigger breaks, and the trigger makes a noticeably loud clicking sound. I know it's not my trigger technique, because none of my other pistols do this, including my Glock 30. When dry firing the 23 with the 3.5# connector and the Glock 30 with the stock connector side by side, the 30 feels much smoother and actually feels like a lighter pull.

I have always kept the Glock 23 very clean and lubricated (but not over-lubricated), and I always put a drop of gun oil where the connector meets the trigger bar.

Any thoughts or advice? Should I take it to a GlockSmith and have him look it over? Would the Glock guy at Four Seasons in Woburn be a decent place to start?

Thanks in advance.

** EDIT: I forgot to mention that I'm a left-handed shooter, for what that's worth.

My only thought is perhaps the connector you installed had a burr or sharp edge & has worn a groove on the mateing surface W/ the trigger bar.

Sometimes the nickel plating will flake off the trigger bar and or connector and you can get that feeling in the trigger.
