High quality, drop-in fit, very attractively priced. Only gripe is that you have to remove the thread protector in order to remove the barrel from the slide, but that would be the case with any similar setup.
I haven't put any rounds through it yet, but will update after I've had a chance to do so on Sunday.
I know it's old thread as I was looking for info on these sights.
Still have them?
How are they doing?
I am trying to justify the cost shooting suppressed instead of just using stock sights.
Just received my stamp and I have not really shot it much yet with the ammo shortage and all.
