Slightly modified Glock 43. New slide plate..TG-H3 sights.. new recoil spring.. new Rival Arms fluted barrel.. index release owb holster..4 mags. This thing is amazing. Best shooting 43 I've shot.... just my opinion. This setup could not be achieved for my asking price. I'm ready to move to the next project so I made sure to price it fairly considering mods. Thank you for looking.
