Holosun 507K X2 - Best Overall
The Holosun 507K is designed for thin handguns and fits the Glock 48 slide perfectly without hanging over the sides.
The 507K is one of the most popular RMSc red dot sight on the market, and I've decided to try it out. The best part about this optic is its lightweight and durable design for range and concealed carry use.
I didn't care too much about the shakeawake system because the battery can also last so long even if I keep it on forever without having to shut it off. It's just another thing that can fail, so I'm not a big fan of that.
Features:
- Magnification: 1X
- Reticle: 2 MOA dot, 32 MOA ring, or combined
- Turret Value: 1 MOA / Click
- Window Size: 0.58" X 0.77"
- Construction: 7075 T6 aluminum IP67 rated
- Dimension: 1.6" X 0.98" X 0.95"
- Weight: 1 oz
- Battery Life: 50,000 hours
Pros
- Side battery access without sight removal
- Very long battery life
- Features Shake awake technology
- Small for CCW
- Durable front lens construction
Cons
- MOA adjustment requires a small flat head screw driver
- Motion sensor for the purpose of saving battery maybe be not so useful for CCW
Holosun EPS Carry - Best Weatherproof
The Holosun EPS Carry must use the K to RMSc adapter plate to mount on the Glock 48 slide along with the DPP Titanium optic plate. This closed emitter optic design keeps moisture and other debris away from the LED emitter screen.
When choosing between two options, I liked the 6 MOA model because I generally prefer a simple center dot reticle that is big enough for me with astigmatism to see.
Overall, the Holosun EPS has all the good things that the 507K has, and its great for range use and concealed carry.
Features:
- Magnification: 1X
- Reticle: 2 MOA, 6 MOA or MRS
- Turret Value: 1 MOA / Click
- Window Size: 0.58" X 0.77"
- Construction: 7075 T6 aluminum IPX8 rated
- Dimension: 1.62" X 1.07" X 0.95"
- Weight: 1 oz
- Battery Life: 50,000 hours
Pros
- Very durable for carry
- Full weatherproof
- Prevents accidental button adjustment in lock out mode
- Very long battery life
- No lens distortion
- No recoil lug trimming required
Cons
- Turret tool required to adjust MOA
Cyelee Cat Pro - Best For The Money
The new Cyelee CAT Pro bis sturdy and robust to withstand the rigors of both range shooting and everyday carry. This durability ensures that the optics can handle frequent use and tough conditions, making it a reliable red dot for Glock 48
One of the standout features of the CAT Pro is its side battery access like the Holosun 507K. But what I didn't like is the tiny turrets that can't be dialed unless I have a small flat head tool.
In terms of reticle options, the CAT Pro only features the 3 MOA single dot. It gets the job done, but I really wished they have a 6 MOA version.
Features:
- Magnification: 1X
- Reticle: 3 MOA
- Turret Value: 1 MOA / Click
- Footprint: RMSc
- Window Size: 0.65" X 0.83"
- Construction: 7075 T6
- Type: Open emitter
- Weight: 1 oz
- Battery Life: 50,000 hours
Pros
- Very durable
- Lightweight
- Very long battery life
Cons
- Turret tool required to adjust MOA
Trijicon RMRcc - Best Durability
The Trijicon RMRcc is as durable as the RMR and is great for the single stack Glock 48. In order to mount the RMRcc on the Glock 48, there are two options:
- Mill non MOS Glock 48 slide for RMRcc
- Buy Brownells Glock 48 RMRcc slide
The best feature I like is the new "LOCK-OUT" mode, which prevents accidental adjustments to the brightness settings when carrying the firearm under clothing. You can rest assured that your settings will stay exactly as you set them, no matter what.
Besides featuring a 7075 T6 aluminum body, the bottom battery loading design ensures that the optic's battery stays tight to maintain good electrical contact, enabling it to withstand recoil and drops effectively.
Highly recommend using a suppressor height front sight to co-witness for faster dot acquisition.
Features:
- Magnification: 1X
- Window Size: 0.5" X 0.74"
- Reticle: 3.25 or 6.5 MOA
- Turret Value: 3 MOA / click
- Construction: 7075 T6 forged aluminum
- Dimension: 1.8" X 0.95" X 0.97"
- Weight: 1 oz
- Battery: 1 CR2032 battery
- Battery Life: 2 - 3 years
Pros
- As durable as the original Trijicon RMR
- Prevents accidental button adjustment in lock out mode
- Very long battery life
- Very slim fit just like the Holosun 507K
Cons
- Milling required (Doesn't fit RMSc footprint)
- Bottom battery access
- Hard to pick up the dot without a tall front sight to co-witness
Swampfox Sentinel - Best Value
The Swampfox Sentinel stands out as a popular choice for the Glock 48 red dot, known for its affordability and seamless mounting. It fits directly onto the Glock 48 slide, requiring no modifications, which is a big plus for users.
In terms of durability, the Sentinel's 7075 T6 body is robust enough for regular carry. However, for added protection, especially for the lens hood, consider pairing it with the IRONSLIDES Shield. This extra layer can make it slightly more beefy as long as you take care of the optic.
Features:
- Magnification: 1X
- Reticle: 3 MOA
- Turret Value: 1 MOA / Click
- Field of View: 1X16mm
- Construction: 7075 T6 aluminum
- Dimension: 1.61" X 0.91" X 0.94"
- Weight: 0.62 oz
- Battery Life: 50,000 hours
Pros
- Easy to mount
- Holds zero
- Affordable
Cons
- Thin lens frame
- Reticle may flicker when facing direct sunlight
- Turret clicks don't have positive feedback
