Thanks, I had already watched this and hand polished some things in my tisas. Already did the trigger bow, hammer, disco rail. I used fine 320 and it did a good job of polishing things up but I plan to go back over everything with a really high grit.
The only thing I have changed out was put in a Wilson flat wire spring and gi guide rod with shock buff.
I know, I know, if our lord and savior JMB thought it needed a shock buffer he would have put one in....made of cured squirrel intestines no doubt...
I am a bit trepidatious about dremeling my pistol.
