New to the red dot optics game...

[cskiles]

I have two questions for any of you that are familiar with or currently run a red dot pistol optic on the EDC.

1.) If you get an optic with the 'shake awake" feature, what keep it from coming on when you are driving and walking? Am I missing something?
2.) Can anyone point me to a thread or article on sighting in a red dot optic?

I am looking at getting either a HOLOsun 507K X2 a Trijicon RMR Type 2, or a Trijicon SRO.

Any help would be greatly appreciated...

It’s pretty much just always on, batteries last forever in those models though.
I’ve only ever used Holosun but I’ve never had a problem with them, I like them over the Trijicon because the battery can be swapped without taking the optic off the gun.
Sighting in is no different than a red dot on any rifle, the dot should come with a tool for sighting in.

Do you sight it in like a scope, off of a bench rest at a paper target? I have sighted in scope all of my life, I am interested in configuring it as a co-witness with my iron sights.

Pretty much all there is to it

Trijicon is good choice. RMR for double stack, RMRcc if it’s single stack. You will have to remove the optic to change battery on these model but the batteries last years with the optic left on constantly. No need to turn it off even if you know you’re gonna leave it in the safe for weeks, or months. Once installing a new battery reconfirm your zero, adjust if needed. Use a quality battery from Energizer or Duracell and change it once a year (birthday), they will last longer than that for sure but if you keep this cycle you’ll never have to worry about the optic being dead and you won’t ever need your irons, in the off chance you do need them though, have them in the lower 1/3 of the optic, not full cowitness (that takes up too much optic viewing space and is just distracting and defeats the point of having the dot to begin with).

If you’re an excellent handgun shooter, sighting in with no rest is fine. If you’re average or below, sight in off a bench rest or bag from about 10 yards, then shoot with no rest to confirm you are hitting what you’re aiming at. If you’re zeroed off the rest but having tendencies to miss one way or another then work on your grip and trigger pulls until you can hit the same spot it’s hitting from the rest. In other words, don’t zero to where your tendencies pull your groups to, zero it properly and then practice your shooting to improve from there

I use the holosun 509t on 3 pistols and after 3 years batteries are still going strong. The circle with dot it good for shooting longer distances as with man size target you can put bottom of circle on head at 100 yards and shot will hit in heart area with gen 5 mos Glock 19. Closer range just use the dot.

Shake away is just marketing fluff. Same with the solar crap. The batteries last a hot minute. Just change your battery once a year. That's a good practice on all RD sights.

Side/top load vs remove to replace battery is overplayed. Overplayed by people that don't actually use mrds' and holosun homers. The only trijicon that you have to remove to replace the battery is the RMR line. Even then, it's minor pain in theory, but it practice, not so much. The only gun that I've had more than a couple clicks of zero shift to after replacing an rmr battery is a Ruger Mk4 and that is due to the optic mount. If you have a lot of zero shift, your optic mount sucks or you didn’t have it mounted properly in the first place.

The RMR is the best option if pinching pennies. It is proven. More-so than any other mrds on the market. Easily finable for 300 - 350 for a ttpe 2 on the used market. Step up from there to an SRO, then RMR HD, then Acro P2 is current king.

I left out the RCR and steiner MPS intentionally

Mrds options to watch: primary HTX and Aimpoint COA

It’s essentially “on” all the time except when stored. The battery life is excellent, so the bottom-mounted battery tray isn’t really an issue, though a side-mounted tray is generally preferred.

For sighting it in, you can zero it at the range like a scope and make adjustments as needed. I typically use a bore laser sighter at home at x, y, z distance and then fine-tune at the range. If you’re interested, here’s an Amazon link: https://a.co/d/8De3xAV.

I own two Holosun 407K optics, and they’ve worked well for me. They’re essentially the same as the 507K, with the main difference being the reticle options. A couple of things to keep in mind: 1) Check your gun’s optic footprint. The options you’re looking at may all be different, and you might need an adapter plate. 2) There’s a learning curve. I got frustrated at first because the dot wouldn’t appear, but it turned out to be my alignment, not the optic.

Hope it helps, and good luck!

RMR Type 1 if you don't want batteries... otherwise, all the Trijicon offerings are pretty nice. I've been running a Steiner MPS for a little while and it's great as well. Currently, I'm replacing everything I have from Holosun.

I've had or have trijicon, vortex, eotech, burris, holosun, dpp, etc and there is NOTHING wrong with holosun. they are great optics. they used to be on the economic side but not anymore. anyone saying otherwise is just a hater. just like mj riders who hate on lbj for no reason, they will try to play the "mAdE iN gYnA" card while typing from a chinese keyboard

PS: keep both eyes open when shooting through a red dot
