Need advice on most reliable shake awake red dot for my P320.

Just beginning the search and wanted to save time by using your experience. The sig with bottom access to battery is worrisome.

The current "gold standard" for pistol mounted optic is the Trijicon RMR Type 2 with the Holosun T508 and T509 coming in second.

Some of us, including yours truly, have very high hopes for the Aimpoint Acro P-2 which is due to arrive end of summer (I have one on order).

Another vote for the Trijicon RMR.

Aimpoint Acro P-2

can you share your reasons for choosing trijicon rmr over others?

I've never actually used a red dot on any of my handguns so I'm curious of pros and cons

I think the biggest argument in favor of the RMR is its proven track record.

Mounted on a pistol slide is a REALLY tough environment for anything electronic.

The RMR has been around for longer than a lot of its competition and has been one of the more popular, widely used slide-mounted optics. While you hear about people having problems occasionally, the overall reliability and durability of the RMR seems pretty impressive.

A lot of competitive shooters have gone to other options with bigger windows, smaller bezels, etc., but also have to send them in a lot more for service.

That said, all that info is second-hand. My only experience with red dots on pistols is an old Burris Fastfire on a Browning Buckmark .22. It was fun but I didn't love it and I'm still leery enough of the bulk and possible reliability issues that I haven't tried a red dot on any of my centerfire pistols.

I have a Holosun 507C-gr elite on my duty Glock 45. Another guy has the same one on his duty. Never had a moments problem from either of them. Other guys have RMRs and have no issues with those.

The Trijicon RMR Type 2 is the industry standard for quality and reliability. Spend some time on searching the topic online and you'll see eleventy-billion reviews.

I'm a police armorer and firearms instructor (been one since 2003) and have the pleasure (or displeasure) of taking care of lots of guns, many with RDO's mounted on them. By far the most reliable is the Trijicon RMR Type 2.

Does it have the best reticle? No, but generally they don't break. Also, everyone (and I mean everyone) offers their milling or plate adapters for it.

Holosun is the new kid on the block (they're Chinese manufactured as opposed to Trijicon which are made stateside) and for the money are pretty good, but sometimes have some QC issues. They also have a dot and ring reticle which some like and some do not. Most of the time their 508T will work on a slide cut for the RMR.

Aimpoints are an enclosed emitter design which has a lot of promise. The Acro P-1's battery life was not great, but if the P-2 works as advertised I'm pretty excited about it.

Those two points are what made it easy to choose the Holosun over the RMR

That they ffit the same footprint of the RMR makes installation a breeze. The 32MOA ring helps in the transition from iron sights..it is also superior when shooting close in. You have the option of just using the 2 MOA dot or both together

The Sig Romeo Pro 1 does not have a bottom mounted battery and is doing well for me. The Delta Point Pro is also a good option.

but to be clear 'shake awake' as that term is often used in not in many (any?) of the best options for reliability.
Nor after aimpoint solves its battery issue with the P2 is it likely needed for any of the best options.

I have the Delta Point Pro, and am extremely satisfied. However it is too big for CCW.
I put the Romeo 1 Pro on a P320 compact, and so far it has been very good. Built in Oregon by a prior Leupold engineer, that Sig lured away.

I will be purchasing a red dot for a P365, it will probably be a Holsun with a green reticle.

I have a 510 green on my SBR for duty. I will get a 507k green for my G48 or 43X at some point.

I like being able to choose between reticle, dot or both. I also like the price and their warranty.

I'd gladly use a Trijicon but I can almost get two Holosuns for around the same price if I find a good sale.

I have a stupid question. If you are using a shake awake red dot on your carry pistol, doesn't it become a battery killer since it should be on all the time with your constant moving around? Can't see carrying it in an off condition in case you need it in an emergency.

I got the Romeo1 Pro for my P320 that I carry on duty the first week of April 2020. It is carried daily and I check the dot each day before my duty shift, I wanted to see how long the battery would last. I replaced the original battery on the 15th of May 2021, so it went a little over 13 months. Now that I know this, I'll likely replace it every 6 months just to ensure I always have a good battery. I will still check it before each shift though.

I read far far faster then my brain can keep up sometimes. I read the OP’s thread title as “Best P320 Shake Weight”. Hilarity ensued in my head.

I return you now to the regularly scheduled thread.

Effectively yes. But the better ones have 3-4 years constant on battery life now on medium settings. change your battery once a year and leave it on all the time IMO. My first RMR battery lasted over 3 years.

This is the first I've heard of the Aimpoint ACRO P-2.

If it had been out last month, I'd likely have grabbed one. Instead, I went with both a RMR Type 2 and a RMRcc.

The LED RMR's (like the RM07 and RM07) aren't "shake awake." They're always on. Most folks that carry one change the RMR's battery every year out of good practice; however, they typically last longer than that.

The Acro P-2 is supposed to have a 5 year battery life from a side load CR2032 battery in a fully sealed unit.

I've run an Aimpoint CompM2 for years under some very harsh circumstances and am sill using the original one I obtained years ago. I leave it on all the time and swap the battery once every couple years.

If the Acro P-2 has the same durability (no reason to believe it won't) it will likely surpass the RMR in the pistol RDO game.

While my RMR 2 and RMRcc are not "shake-awake", I do appreciate their auto-brightness mode wherein they adjust to the ambient light. I've tested it out fairly extensively with my RMR 2 and have found it to be very quick to adjust and pretty accurate in terms of making the dot slightly on the brighter side than necessary, which is a safe side to err on.

In the gun safe, the dot is very dim. Pull it out or even shine a flashlight in there, and it kicks up.

I even checked it with a weapon light, and the dot never got washed out as the sensor was able, at least inside a structure, to pick up the wash of the weapon light and adjust the dot accordingly. Trijicon does good work.

The issues with auto-adjusting brightness manifest most obviously when there is a disparity between the brightness at the pistol and the point of aim. The big times that come to my mind are when using a weapon light in the dark and when pointing the gun from a darkened area to a much brighter area. The optic will adjust for what it "sees" and that will generally be too dim. Obviously the amount of disparity and the distance between pistol and target are factors.
