Lens Size

The size of the lens help you find the dot faster on target. Since the Ruger 22/45 LITE has that 1911 style grip angle, it’s very easy to present the gun and acquire the dot off draw.

Among the 5 products, the Vortex Venom and Holosun HS407C just feel right in the hand with the right amount of glass window for the shooter to see through.

Fast On Target

SRO Dot Size

A red dot optic on a pistol makes acquiring the target fast without aligning the sight picture at all. The brightness of the dot, sight weight, sight height and the size of the reticle are all important aspects of a good handgun sight while staying low profile.


Effective Range of 22LR

Is using a red dot sight over kill on a 22LR pistol?

Even through 22LR isn’t considered a high precision caliber for long range shooting, but it’s damn accurate up to 150 yards though the most effective range is 100 yards before dealing with the large ballistic drop.

Shooting standard 40 grain CCI 22 High Velocity ammo with 1235 fps, you can expect between 0.5 to 0.9″ diameter shot group at about 25 yards with a 1 or 2 MOA red dot reticle.


What Distance To Zero The Sight For Ruger 22/45 Lite

Ruger mark iv range testing
Image Referenced Iraqveteran8888

When zeroing the red dot sight for the MARK IV 22/45, 25 to 50 yard zero are good distances to zero your sight.


MOA Dot Size

1 MOA to 3 MOA dot size for a 22LR pistol is enough for getting effective hit up to 100 yards.

The bigger the dot over 3 or 6 MOA will cover too much of the targets up close for a 22 caliber zine bullet hole.


Is Mounting An Expensive Red Dot On A 22LR Pistol Necessary?

The answer is NO from the perspective of cost and its very much up to the shooter if he/she wants a $600 Trijicon RMR on a 22LR. Generally speaking a expensive sight goes with high recoil calibers.

Optic like the Burris FastFire 3, Vortex Venom and Sig ROMEO1 feel like they will break on a 357 sig, but on a 22LR it will be just fine.

So it’s NOT necessary to have an expensive optic on a 22LR pistol, again… its all up to your budget.


Round Up

The Holosun HS407C is the best red dot sight that has the strongest build quality over others. Extremely long-lasting battery life and performance is why we’re recommending.

The next option is the Vortex Venom for its lightweight and slick feel on the Mark IV.

No matter which optic you pick you will have a blast on the range whether you’re teaching a beginner shooter or plinking, you will not disappoint.
