I lost my connection for sight sales/install due to them retiring. I am looking for someone or a business who can sell or install night sights on a Glock 9mm. Does anyone have someone they suggest or go to for this?
Not exactly the answer to your question but it is super easy to do yourself.
Dawson sends the hex driver and an aluminum punch in the package with their sights. It’s super straightforward.
Colorado School of Trades gunsmithing school. They aren’t fast but good prices and great work. I’ve had them do many sights, including an XD that they had to mill the back sight out of.
