I love shooting both my TX22's but the one thing that bothered from the first time I picked one up was the finger groove finding it very uncomfortable with a firm grip.This morning I couldn't stand it any longer so I broke out the dremel and got to work. Started with a coarse sanding disc, then moved to a fine disc finishing up with a 600 grit wet/dry sandpaper. First time trying stippling so I rounded off a soldering iron tip and gave it a shot. On reflection maybe should have left it a little sharper. Either way it's a much more comfortable grip.
