Glock A-cut & Aimpoint COA

[Dave0317]

I think it’s obvious this is an improvement over the MOS system.

But, is it an improvement over a direct mill RMR cut?

I’m not an engineer, but it appears that a lip of metal on each end is a better way of locking down an optic than the usual trust we put in the shear force strength of screws. Though, you are now relying on 2 screws to not come loose instead of 4, and if they do come loose, you are losing your dot and your rear sight at the same time.

Another advantage is the optic sits low enough that regular height irons are visible, this also results in a iron-sight trained shooter pickup up the dot quicker/more naturally.

I’ll probably wait for the Sage Dynamics review/drop tests before I spend my money, but this looks like a more durable mounting style. Only downside is if it does not catch on in the market, you are stuck with one optic and a footprint no one else is using yet.

I have not had a slide cut for a red dot of any kind, I have only used the plates that replace the rear sight. So far those have worked out very well for me. I haven’t had a single issue with them yet.

It’s pretty hard to beat the p2 direct milled into the slide for a bomb proof setup. I guess this is an upgrade if you wanted a closed emitter on a 43/48. Problems with the MOS system are also overblown, it’s not as solid as direct mount but it’s not far off.

I’ll be in for a pair of g19s as forever guns after they have been out a year. At this point I don’t see how you practically improve much on the system. A g19 gen 5 is near perfection for anything I have ever carried a gun for (plain clothes, off duty, piles of high risk operations) and the Aimpoint with a quick change battery is the other part of the perfect combo. I’m currently running an issued m&p milled with acro (battery life could be better) and a pair of g19s cut for RMRs. I actually shoot the RMR/G19 combos 10% better.

Not as formal as Forms drop tests, but I think it shows this optic and footprint has some potential.

I got to play with all 4 versions of this in January. The cut makes the most sense of any I have seen. Think of it like a snow ski binder where you put your toe in and then lock down the heel. The optic is slightly smaller than the Acro but the window feels bigger. I think it’s from the fact the battery has moved. The fact that you can get the same optic on full size and slim line guns is awesome.
With how they have this priced for LE, it’s going to be very popular.

Shop finally got a G19 and COA combo in. Bought it and got it zeroed. Not a ton of rounds through, but enough to say I like it.

Window definitely feels like a lot of usable space, even though on paper it’s one of the smaller ones.

It also sits lower than many optics. I see this being an advantage for guys transitioning from a long period of shooting irons. Even with the muscle memory of bringing the irons into alignment, you catch the dot on the way there. Some optics sit so high that an iron sight shooter will end up not seeing irons or the dot, due to it sitting so high.

The gen 5 as a whole i think is one of the better iterations of Glock. My gen 3 trigger still feels better, but it’s got thousands of rounds through it. This one may break in to be even better, but out of the box, it’s smooth but less of a defined break.

This will be my everyday CCW. Im still torn on if I prefer a RDS for backcountry use. But for everything else it has some huge advantages.

I can’t speak to the ruggedness of COA but it’s my favorite cut/optic combo. I have several RMR and RCR pistols but the COA just feels better. Easiest to acquire and target focus by far. Sits low, clear glass, thin bezel.
