OK, I have had two sets of replacement glock sights installed by a "professional" armour,
then I purchased and installed three more sets on my own using the MGW sight pusher tool.
All were TruGlo TFOs.
My issue,... how important is it for the sights, both front and rear, to be absolute "true" dead-center
on the slide? AND what is the best way to "assure" that they are at true dead-center?
Is there a tool or device to obtain and set this measurement?
Thanks.
