My first one that's mounted on my carry gun has been carried daily since August of 2022. I've adjusted zero on the gun once since I mounted it, but it was an exceptionally small adjustment (two clicks at 25 yards) that could just be explained by a different lot of my carry ammo. (124 grain +P HST)
I made the adjustment because it was just a hair to the left when I shot some bullseye and then I checked it with some carry ammo and found the same issue.
I took this optic directly off my old carry gun (Gen5 G17) and installed it on this one without even re-applying more VC3 to it.
I ended up shooting the entire scored day of Professional Pistolcraft Instructor with it in December...and I ended up winning Top Gun and posting the highest score on the Pistol Master standards...with just one shot slightly into the 9 ring leaving me with a score of 99.6% on the bullseye portion of that exercise.
At this point the gun has seen probably close to 4,000 rounds with that mounting of the optic plus the movement and vibration that comes with daily carry. Zero movement from the optic.
The one I purchased for my training gun some time later eventually experienced a failure of the controls. I only noticed because I was in the middle of a class and I went to adjust the optic to do some precision work and the dot no longer responded to the buttons. I knew that a federal agency was experiencing the same thing with some of their units that they were getting about the same time as I got mine, so I wasn't worried. Aimpoint had me a replacement in less than a week and that optic has been mounted to my training gun since June. It's been through at least 5,000 rounds since then without further issue.
No optics company is shipping perfection these days...not that any ever did...but Acro issues seem to be few and readily resolved by Aimpoint. I have no trepidation about mine or buying any in the future.
