Hi all,

I just registered on this forum, and I look forward to contributing & learning more. Apologies in advance for the lengthy post & possible typos!

I just purchased a Glock 40 10mm MOS and I love it. My primary use case is home defense. Occasionally, I plan to hunt with it (hogs mostly, maybe deer). I take trips to Wyoming 1-2 times per year, so maybe I’ll take it with me on various excursions there…

My reason for posting – I am looking for recommendations on a red dot sight that will serve both my primary use case (home defense) & secondary use case (hunting). My budget is around $750 max. My other firearms have stock sights, so I have never purchased a red dot or aftermarket sight before. I have used my friend’s red dots, but I don’t recall the make/model.

I’ve asked around, and I consistently hear that Trijicon’s “are the best.” I am sure it varies with personal preference & there is no “best.”

In my own red dot research, I’ve come across MOA and how that may be a factor in my decision. The Trijicon RMR Type 2 Adjustable LED reflex sight comes in 1.0, 3.25 & 6.5 MOA. If I’m correct, lower MOA is for longer range uses, while higher MOA is for short range uses. Does it make sense that 3.25 MOA would be ideal for me, given I will be close-range for the most part with home defense, and occasionally hunting at no more than 50 yards (estimating…I don’t plan on taking a shot further than that at any game). I would enjoy hearing more commentary around MOA, and if I’m on the right track.

Lastly, I may be looking to add a flashlight later down the line if I need to shoot in the dark quickly… I'm not sure if adding a flashlight would impact the decision on what red dot I choose.

So, knowing my use case & background, what would you all recommend, and why? If I'm way off and there's a totally different sight you recommend, please let me know.

I'm hoping there's a local range or shop that will let me try before buying.

I’m happy to add more color to my use case & story if that helps.

Thanks!
 
Welcome to THR.
Does it make sense that 3.25 MOA would be ideal for me,
the reticle dimension will be a personal preference thing. A 3.25 MOA dot will be equal to a little more than an inch and a half spot at 50 yards, 3.25" dot @100 yards and a 6.5" spot at 200 yards if that makes sense.
I don't own a pistol with optic but have shot them some, i like the trijicon rmr form factor and reputation. That said the vortex venom is about $250 retail and looks similar. I would be tempted to buy the vortex and see how i like it, can always sell the venom towards the purchase of an rmr if you want to upgrade. I believe vortex has a very good (lifetime?) Warranty. Don't have any other suggestions, sorry.
 
Thanks for the recommendations. I like the idea of the TTRL that has a flashlight & laser, however, it seems like the laser would be useless in the daytime?

Perhaps I can have it mounted most of the time, and take it off for hunting to add a Red Dot.

Ended up getting a Trijicon SRO 1 MOA and some Trijicon Bright & Tough Suppressor Night Sights. Got it mounted last night and will fire it soon!

I liked the larger field of view on the SRO compared to the RMR. I read reviews that the SRO is not as durable, but I don't anticipate carrying it every day or being rough on it. There is a great YouTube video with a side-by-side comparison of the SRO & RMR here -

I'm interested in your opinion of the 1moa dot. I'm also looking for a red dot. I'm pretty much looking at trijicon rmr2, sro, or holosun 507c. They all share the same footprint and I'l be sending a slide to primary machine for optic milling.

At $460-525 the trijicon has me pondering deeply due to cost.

Trijicon has 1.0,2.5, and 5.0 moa dot
Trijicon uses 1moa adjustment per click
8 brightness settings
1.6 oz

Holosun has 2 moa dot
Uses 1/2moa adjustment per click
10 brightness and 2 night vision settings
2.65 oz

The weight difference and known superb quality of the trijicon has me leaning on it and just keep saving money. That being said I'm still uncertain on the dot size. I've got a older Optima 2000 dot on my 44 mag which is a pretty small dot but I truly can't say what it is. A gift from my father from years ago 20191222_082741.jpg

My ocd is overboard due to the cost.. I kept reviewing each of the red dot choices while writing this post!
 
With all slide mounted dots the big question is how many rounds a year are you going to put down range. Just sent in a delta point pro off of my G17 USPSA gun the only made it 8000 rounds, 10mm is going to beat one up faster, so go with the best warranty. The trijicon RMR has been out in the wild long enough to have a good track record. 2.5 to 6 MOA dots are going to work better than 1 MOA for fast shooting. The SRO is sweet, but is having some growing pains in the high round count games, I'm sure the bug will get worked out. The bulk of shooters will never have a problem withe most of the dots out, so the makers will never build them to stand up solid for long term high round count use, enough are sold too justify replacement to the one that get heavy use. That said I just got a second 2.5 delta point, so I have a back up.
 
When reading reviews, definitely look at reviews Specifically mentioning the 10mm, 40SW, and .357 mag guns. Reviews on a 9mm pistol are good for function, but on a 10mm you need to understand how it’s going
To handle recoil.

Another thing to consider is where you want the slide milled to take the sight. A rear mount is in the optimal position but it usually forces you to remove the rear sight. A “tactical” mount moves the optic forward slightly leaving room for the rear sight to stay put, but in some cases leads to brass strikes on the slide mounted optic which is not good for accuracy or durability. Holsters are getting much more common with capability to hold a pistol with optic, but it’s still something you need to consider if you go with a sight that’s physically large.
 
Not trying to stir the pot, but home defense and 50 yds< might want to consider a good set of night sights.
No switch fumbling, battery issues, or night blindness starring through a bright dot in the dark, during high stress situations.
Being proficient with both, just a suggestion.
