So, around 800/900 ish rounds (and 2 or 3 times that in dry fires) in, I think I have my first issue with my Micro dagger. It seems the firing pin and cruciform (point where the trigger bar interfaces to the firing pin) are wearing on each other notably, and causing the trigger pull to degrade on an ongoing basis. When I first got the Micro, it was the lightest/crispest/nicest trigger on any of my Daggers (and I have some very nice/worked on triggers on several of the full size ones). Now, it’s the heaviest and grittiest of all my Daggers (about on par with a factory Glock trigger now, LOL). I took some close-up pics best as I could with a cell phone to try and show the problem(s).
First up, the point where the firing pin interfaces with the cruciform - note that divot on the left side of the pic. That was not there when it was new.
Now the back end of the cruciform - note the raised/sharpened ridge on the left side that corresponds to that divot we see on the firing pin.
A backed-out photo of the cruciform (a bit better focus).
Top view of the cruciform - note the wear pattern on the right hand (if you were at the rear of the gun) side. Also note the slight protrusion on the left side that corresponds loosely to the firing pin divot. It kind of looks looks like the pin swiping the cruciform during slide cycling is wearing into the cruciform, creating both a sharpened edge, and as it wears away more on one side than the other, a protrusion.
Close up pic of the firing pin - notice it’s more worn on the side that corresponds to the wear on the cruciform than it is on the other.
It’s not the worlds biggest deal, about 5 mins with some ultra fine grit sharpening/polishing stones should smooth the rough points out, so mostly just making a note here that I observed this in case it helps someone else out.
