Received all the parts and did the slide-on-frame assembly Thursday.
Function checked it Sunday with 2 mags before calling it due to health issues (somehow I picked up rice rabies again).

I did notice after 6 - 8 rounds that the trigger vibrated enough to make my finger numb - is this normal?
I tried using just the pad of my trigger finger as well as the in facing joint crook with the same results.
Do I need to upgrade the trigger?

Full disclosure I have only ever fired one other striker actuated pistol, my Springer XDM-10 and it doesn't do this.

I only bought a frame and added an aftermarket slide - Mine doesn't create numbness or pain in the finger after shooting - so no, I do not think its normal - That sort of sounds like a trigger slap sensation, not sure how that would happen in a glock-design.

Put 2 more mags through the micro, trigger vibrations seemed less pronounced this time.
One thing I did notice is after 4/5 founds the barrel gets warm and accuracy deteriorates.
I guess this is to be expected in a 3.5" barrel?

Otherwise I'm pretty happy with it.
Noticed frames were back in stock today and a few complete guns, maybe I'll get another one to mess with?
