I was dry firing my 34 the other day and noticed the trigger pull had gotten nasty (not smooth, heavy). It's got a factory 3.5# connector and trigger (both polished). I took it apart and found that inside bottom edge of the trigger bar (where it rubs the connector) was rough and had actually carved some shallow grooves into the connector. I used a file to radius the rough edge of the trigger bar, followed by polishing. Anyone seen this happen before? I had to polish the heck out of the connector to get rid of the scratches the trigger bar had put in it.
