Problem at first - G-Sight Spectre Elite Laser Sight

I give it 5* even though when I first got it like another review the mount didn’t work because the bolts were to short, so I emailed g sight themselves and they responded quickly and apologized for the short bolts. They asked for proof of purchase and my address and quickly sent out a new mount with the correct longer bolts, it took maybe 5 business days to receive but as soon as I got it in the mail I slapped it on and got it sighted in with the sightmark 9mm boresight I bought off optics planet as well. Haven’t shot it at the range yet but it shouldn’t give me any more problems.
