Had two more front BUUS come loose yesterday at work. One was loose in the dovetail and one disappeared and was not recovered. Shooter with the first gun noticed the BUIS/RD co-witness was off during a string of fire.
We’ve had about 300 P320’s with Romeo1PRO RDS and SIG suppressor height BUIS in use for about 6 months now.
So far we’ve seen far more failures of the BUIS than the RDS. So far we’ve seen over 20 BUIS come loose, vs 5 issues with the RDS. Those RDS issues bring 3 which lost zero in the same manner (low left) and two which started worked eating batteries due to failure of the shake awake mode. Most of the BUIS failures have been front sights.
The three zero shifts were all from the same batch of sights. The two shake awake failures are from a different batch of sights issued to our SRT team members about year ago.

I think tall backup front sights on optic guns will be vulnerable to this, snag-prone and such.
