Best Sig Sauer P320 X5 MRDS

Sig Sauer P320 X5 with ROMEO1 optic

The weight was increased to 43.5oz with TXG tungsten-infused grip module ion order to reduce muzzle flip by about 50%. The trigger pull of the XFIVE Legion is ~30% lighter with the new skeletonized trigger, which increases shooting speed and accuracy.

The recoil system has been upgraded to use a solid steel guide rod and a 14lb 1911-style spring.

Pairing this thing either with a Sig red dot or other red dots on the market will make this thing kick ass on the competition stages.

Best MRDS For Springfield Hellcat OSP

Springfield hellcat OSP

The NEW Springfield Hellcat OSP has finally entered the micro pistol arena against guns like the Glock 43 & Sig P365. The gun's biggest winning point is its extended magazine capacity in a palm size pistol.

Best Beretta M9 Red Dot & Mounts

Beretta M9 Red Dot Sight

Can You Put A Red Dot On A Beretta 92fs (M9)?  The Beretta M9 or 92FS slides can’t be milled like other striker-fired handgun slides.

1. Not enough room for a base mounting plate
2. Milling the slide milling will destroy the gun

Milling the slide will destroy the critical functionality of the Beretta M9!
Please use the rail mount sight adapter OR the dovetail rear sight mount.

Unfortunately, the new Beretta M9A3 has the same slide as before, so there are no proprietary ways to install the sight without any modification.

However, the rear sight is adjustable and removable, which means a dovetail rear sight adapter is your best option for adding an optic.

Best HK VP9 Optics & Dovetail Mount

HK VP9 tactical slide with trijicon RMR

The HK VP9 has gone through several iterations to make it better, and one of the improvements on the newer models is the optic compatibility right out of the box.

The VP9's grip angle is extremely comfortable, which makes it fairly natural to shoot with a red dot optic.

But...For the original VP9 users, mill the slide for an optic or get a dovetail optic mount are the only options.

What To Look For

Low Bore Axis VS High Bore Axis Differences

Pistols such as Glock and Smith Wesson M&P have low bore axis, which makes them easier to handle recoil & faster follow-up shots, because the bore of the gun stay as close to the top of the shooter's hand as possible.

If the physical world allows, we want semi-auto slide operated handguns to have similar to the revolver's grip angle where the grip is almost right behind the barrel, but with modern slide operated handguns that's impossible.

Lens Window Size Matters For Easier Dot Tracking

Trijicon SRO Vs RMR Dimensions

The size of the optic window matters because it gives you extra room to find the dot. Not being able to pick up the red dot fast while using a small window sight on a low bore axis handgun is one of the biggest complaints regarding handgun optics.

Trijicon SRO is the newest optic on the market that has a large window that solves the problem.

Shooting with two eyes open with a larger sight makes it so much easier and fun.

Over the years, many people train hard to be able to pick up the dot consistently for their unique handgun, but the problem is that your perfectly trained techniques may work with one gun, but doesn't work well when using another gun with slightly different grip angle or ergonomics.

Therefore having a slightly larger window helps a lot by eliminating the need to have a perfect pistol draw.

Reflex Red Dot Aids Aging Eyes

Red dot sight is great for distance shooting for handguns. Depending on the dot size of the optic you use, varying from 1 MOA to 6 MOA. The smaller the dot size the more refined the dot, the more you can aim accurately.

In fact, shooting handguns with red dot sight gives you faster target acquisition, and it's perfect for aging eyes where it's easier to aim with the dot than with iron sights.

Does The Weight of Optic Affect Slide Operation?

Referenced SuperSetCA

Generally speaking, handgun optics weight don't affect slide operation at all. They're all very lightweight about 2 oz, in addition, the removed material on the slide for optic mounting balances everything out.

It doesn't increase the felt recoil or anything else like that, so you will be just fine.

The weight of the optic doesn't significantly affect the performance of the slide. However, the only time weight could affect the operation is when mounting it on slides with lightening cuts or with special low recoil springs.

Recoils Resistent

These red dot sights are made to handle sharp recoil forces to retain zero for accuracy. Most high-quality handgun optics are built from the ground to handle loads like 40SW, 357 Sig and even 40mm.

So they can handle a lot of G force when the slide cycles repeatedly.

Repeated recoil only damage the optic's internals if you use low-quality optic.

Handgun Slide Optic Compatibility

GLOCK Slide optic mounting plates

Red dot sights can be mounted on most handgun slides, but not all handgun slides are compatible with optics.

Generally speaking, striker-fired semi-auto pistols are the most popular platform for having a red dot sight on top.

In recent years, major gun manufacturers started to roll out optic ready pistols to the market, and it's been a successful trend.

Companies like Glock, FN, Springfield, Smith Wesson, and more all offer optic ready pistols right out of the box, so that the customers don't have to spend extra money or time milling the slide.

Most handgun optics you purchase will ship with all the mounting plates and screws for your particular firearm, so you don't have to worry.

Battery Life

Small handgun red dot sights surprisingly have great battery lives right around 50,000 hrs using just 1 CR2032 battery. Whether you pick the Trijicon RMR or Vortex Venom, they will stay on always.

Recently, there are solar-powered red dot optics such as the Holosun 407C as a way to increase the reliability of the sight even if the battery fails in the field.

When picking an sight please pay attention to the how easy it is to change the battery, we recommend the ones that allow you to change the battery without removing the sight to prevent loss of zero.

Trijicon SRO and Deltapoint are two great examples with top-loading battery compartment.

Adjusted Brightness Settings Control

All of these optics have favorable brightness level settings that will work indoor and out on a sunny day. The brightness of the dot may appear that the dot size has increased, however, they're not the same thing.

For optic shooters it's important to dial the brightness level to the correct setting depend on the environment, to prevent the dot from being too bright that covers up the lens and the target, or too dim to see.

Picking MOA Reticle Sizes

Red Dot Sight MOA Sizes

Bigger dot for speed, smaller dot for accuracy.

The bigger the dot size the faster you can see the dot & place it on a target and shoot, and this is helpful for fast action CQB shooting & competition.

So choosing among MOA sizes, think about what your typical shooting activities are.

So which ones?

Something like 3 MOA to 6.5 MOA are great for close quarter.

Generally speaking, we recommend 2 MOA or 3 MOA as the middle option. Whether if you're doing competition shooting or personal defense, both of them work.

For precision shooting

1 or 2 MOA dot sizes.

A smaller bright dot is great for long-distance target shooting without obscuring the entire target, so you can see clearly and get pinpoint accuracy.

Is Motion Activated Optic Feature Necessary?

There are optics on the market like the Holosun HS407c where the red dot will automatically turn off when not using, and it will activate when you pick it up due to motion. It's a nice feature to save battery, but it's not a must-have feature.

Most red dot sights can remain on for ridiculously long hours without failing.

In other words, don't pick a red dot sight just because of the motion sensor-activated reticle feature.

Final Thoughts on Handgun Slide Optics

Red dot optics for handguns are here to stay. It helps the shooter to shoot fast, accurately without completely align the sight picture, which means shooting accurately is easier on the move or in improvised positions.

If you want to mill your slide for a particular optic of choice, there are plenty of services available now. Simply order online, ship it to the shop and get it back.

On a low bore axis handgun, we recommend a large window sights like the Trijicon SRO to give you more room to pick up the sight without any effort.

A high quality handgun optic will stay on the slide and endure the repeated sharp recoil without losing zero, and it's also very important to pick the right dot size for the right shooting styles.
