I took my Bersa Thunder 9 UC for some range time and was consistently hitting left. Well left. I've never been great with it, but not this bad. I mean, same day I was shooting my snub dead on. I rested it and it was shooting left for a good reason...it was sighted that way. The sights aren't adjustable per se, but dove tail iron sights can be persuaded. Perhaps it got knocked at my last range session or something. So I reached in my range bag and retrieved a precision instrument: a little wooden mallet from Joe's Crab Shack...with masking tape on one end. I knew it would come in handy one day. Several hard taps to the right (unloaded, of course) and took several shots. Seems I over-cooked it a tad. A couple taps back to the left (again, unloaded) and BINGO!!! Took the center out of the target the next go round from 12 yards. Had 7 rounds in the mag and all 7 were in the center ring and the center dot was gone. I think I got it dialed in...the old fashioned way. I hope it stays put.
