I recently posted a comment in which I said that putting grease between the trigger bar and the plastic frame (thin, right side) significantly smoothed the trigger pull.

With the slide off trigger actuation shows that the trigger bar barely touches, even may not touch, the inside of the frame.

With the gun reassembled, trigger action causes a noticeable movement of the frame on the right side, indicating that the trigger bar is rubbing on the frame. I can't see anything in the slide that would cause the trigger bar to move towards the frame but it does on my SD9VE CA.

You can see, and feel, the frame flex.

Is this unique to my gun or is it a normal action?

[This may not merit a new thread and if anyone objects I will take this down.]
