You made need a diamond embedded dremel attachment to do the filing.
I've got one shaped like a flame and I was gonna use the very tip (fine, fine point...) and just nick the bottom of the bar. Then chamfer, sand and cleanup as necessary. If it goes well I might know tomorrow.You made need a diamond embedded dremel attachment to do the filing.
I'm gonna use a fine, fine Dremel bit shaped like a flame. Using the tip for the initial "nick" and then clean the area as needed to make sure all edges are smooth. I just wasn't sure how helpful the new style trigger bar 's notch was. Figured I had an older one with smooth shoe. Why waste it? Just wanted some input on how doing it would improve the trigger bar. Got the old stepped shoe bar in for now, I'll play with it tomorrow.I've done it prior to ordering a new-design Gen3 trigger bar. It's difficult to determine if it helped as not all trigger springs will break in old-style trigger bars..
...buy the new spring and trigger bar and connector.
The post-2010 improvements are designed to reduce coil trigger spring hook failure. The current Gen3 Trigger With Trigger Bar reduces stress leading to hook failure at ONLY ONE END of the trigger spring. But...most reports indicate that the coil trigger spring hook fails more frequently at its OTHER END which is attached to the Trigger Mechanism Housing. A current TMH is required along with a current TWTB in order to get any real improvement in coil trigger spring service life.... buy a new TB and a "." connector.
First off, thanks for taking the time to write all that in way of explanation. I thought the notch in the new triggerbars was to align the spring, too, for some benefit. The smooth-trigger non-notch bar has been there for a while. Thing is, I used the NY1 spring combo so it was not an issue. Reading some of Butch's recent posts convinced me to go back to the old connector and coil spring.You will make things much worse by half-a$$ing a groove or notch at the pre-2010 trigger bar's coil trigger spring attachment point. Besides, the short simple TS attachment point on a pre-2010 trigger bar doesn't even need such a thing.
What he said.... I guess...What a terrible idea!

The changes made to Gen4-style trigger bars and to post-2010 Gen3 trigger bars distribute the stress across a length of the TS hook...instead of all the pressure being exerted at just one point on the hook. This improved trigger bar design has added curved metal surface on which the hook lays and a groove on that surface to help keep the hook aligned properly on the curved surface. But these changes actually make it much easier than the pre-2010 version to reassemble the pistol with the Trigger Spring hook incorrectly canted left or right, if there is inattention to detail during reassembly.
There's no grinding or cutting or filing or drilling or anything else on a pre-2010 trigger bar that will create the improvements of the new trigger bar design for reducing trigger spring hook failure. The rough and sharp edges left by an amateur rework attempt are much more likely to cause coil Trigger Spring hook early failure than had everything just been left alone.
Also, it seems historically that the trigger spring hook fails more often at the other end, where the trigger spring attaches to the polymer trigger mechanism housing. The post-2010 TMH corrects that as well by rounding the TS attachment point on the TMH.
The only wise approach to all of this is to install a current Trigger With Trigger Bar AND a current Trigger Mechanism Housing. They will have all the proper improvements. Be sure to install a new coil trigger spring as well.
One of the nice things about the Gen5/G42/G43 design is the redesigned hookless trigger spring that should almost never fail. The pre-Gen5 coil trigger spring is the part that breaks most often on a Glock pistol.
