Installed my new Blitz front sight today. Had to use the feeler gauges to make sure it was on straight but looks good and bright. The triangle should be precise. It is higher than stock but as others have used it I think it’s only a click or 2 adjustment on the rear. I was surprised beretta doesn’t use a lock washer but at least they have a locking nut so that should hopefully be it. I didn’t use any thread locker. My CROM arrived today as well but my RMR is out of town so it will have to wait till the weekend
