If you’d like the Glock sites you should at least by the steel ones because if you have to rack your Glock off of a table or whatever object if you want to gun fight and you only get one hand for whatever reason that you can use the plastic OEM sides will break but that’s if you’d like to go outside you can get the metal ones real cheap I will look it up real quick it’s been a while since I’ve seen where they had them cheap there you go Amerglo you can find them suppressor height you don’t even have to have a suppressor or read that I still like the taller sights
