See you in Denham, Bj pawn or gold n guns, or they have another gun shop on Florida blvd inbetween them two, or just buy the tools, it’s super easy
You can order a Glock front sight tool off of Amazon for about $5 and use a brass punch for the rear sight or take them to any place that sells guns and have them do it for you.
Do not use a punch to install Night Sights. Use the proper tool for the job.
