Micro Pistol Sight

Hover to Zoom

Steiner brings battle-proven durability and mil-spec ruggedness to pistol red dots with the NEW MPS (Micro Pistol Sight). All-metal construction and enhanced sidewalls completely seal in the emitter. A recessed window with a metal hood blocks objects from reaching the front lens making this one of the toughest pistol sights ever created. 

At 2.05 oz, the Micro Pistol Sight is compact and lightweight offering Steiner quality glass and a robust feature set including 8 brightness levels, and 13,000 hours of battery life. 

The 1X magnification offers an undistorted image for both eyes open operation and complete situational awareness. The Micro Pistol Sight is designed to fit an ACRO footprint and is compatible with most optic-ready pistols using ACRO baseplate adapters.

Steiner Micro Pistol Sight Lifestyle

Battle Proven Durability

The MPS boasts an enhanced extra side wall that produces a best-in-class shock rating. The completely enclosed laser emitter is water pressure tight making it reliable in the harshest environments and any weather condition.

Compact Size

Only 58g means the sight is light and compact. Its short size avoids any “tunnel-vision” while the low weight allows a perfect use

Daylight Bright dot

8 brightness settings (two night vision) can easily be managed due to the ergonomics of the raised button on the side of the optic. The 3.3 MOA dot allows fast and smooth target acquisition in any condition.

Battery Life

The 13,000 hours of battery life puts the MPS on top of its class and the easily accessible battery compartment allows changing the battery without dismounting the MPS from the gun. A flashing red light indicates low battery.

True 1X

The 1X magnification allows both eyes open operation and complete situational awareness.

MPS is rated 4.2 out of 5 by 6.
Rated 4 out of 5 by from Great sight but confusing advice from Steiner! I wanted to have an Aimpoint Acro-P2 because I already have a P1 on one of my pistols. After waiting for months I decided to give the Steiner MPS a go after watching a review done by Sage Dynamics on YouTube. Was excited to get the sight and immediately loved it. Mounted it on a new Walther PDP 4" but had to order an Acro plate from CHPWS as recommended from the website since the supplied plate doesn't work at all. I was a little confused with Steiner noting in the manual to make sure you install a steel plate but recommending CHPWS (No issues with them, have 3 other plates from them and have no issues) which offers aluminium plates. I spent the $95 for the plate and the shipping and installed it and it looked great. Took it to the range today to sight it in but had some issues with the sight seeming to lift from the plate towards the rear sight. Went home and this is what I found. The plate couldn't handle the sight and is now ruined. The sight look OK with no visible damage. Already ordered a new plate from CHPWS to see if this is bad luck or bad advice/instructions from Steiner.

Rated 5 out of 5 by from Its tuff I been testing this out for a few days. I tell you its tuff. It holds the zero perrfect no matter how rough you are on it. And I have been rough on it! Very happy so far. It lives up to the name.

Rated 3 out of 5 by from DOES NOT FIT ACRO MOUNT Please stop telling customers this fits on an ACRO mounting system! It does not! The mounting rail on the rear of the MPS plate is far wider than the ACRO, which won't allow any engagement with the mounting system of the MPS. The forward rail is the same size, however, mounting an MPS on an ACRO adapter plate will only result in engaging half of the mounting rail leaving a very wide gap on both sides of the rear. That gap is where movement can occur, creating an unstable connection.

Rated 3 out of 5 by from Great optic, instructions are utterly useless 500 dollat sight and the manual is worthless... I Love the sight but aside from showing how to mount it properly they do nothing to show or explain the features. Steiner please put a better manual online on how to lock the sight, remove the 13 hour time off, and use the features of this optic. You have a manual in several languages and it explains nothing.

Rated 5 out of 5 by from Incredibly tough and Great Company This is my new favorite pistol optic. It is incredibly tough and mounts solid to my ACRO cut slide. The glass is super clear and blocks reflections well. The original instructions were a little difficult to follow but they listened to customer feedback and improved their user manual and website.

Rated 5 out of 5 by from Truly the finest pistol red dot I've owned. After running through options from Burris, Holosun, and Trijicon I finally have my "forever" handgun optic. I have had dots obscured no less than 5 times over the years by obstructions(dirt, mud, sand, water, and even soda) that rendered my pistol optics unusable. I truly believe this optic will stand up to all of that and more, and still have a nice crisp dot on which to aim. I only have 300 rounds through it, but so far so good. The window is much larger and nicer to view through than the Aimpoint Acro, and with the emitter on the top of the optic, the window sits closer to the slide than any of the other optics I have tried. The only feature I could see myself wanting to add is an auto-brightness option, but with the battery life as good as it is, I'll just leave the optic on higher than normal and swap batteries each year. The only negative thing I have to say about it is the packaging it comes in. Even Holosun has a nice molded foam box with a hard top and a slip sleeve. I was a little disappointed in the cheapie box it came in for the price of the optic, but hey, if it's as nice as I believe it to be, it will never have a reason to go back into that box. All in all, Steiner has gone above and beyond for me on another optic I own on which I stripped a hole through my own fault. Steiner has me sold on both their products and their customer service and now my shooting buddies are literally looking for the best deals on the MPS to equip their handguns. Word travels Steiner! Keep up the good work, and market this thing better!! People need to know this thing exists!

Can you mount it on a AR15

Asked by: Jr9mm
Yes absolutely. You'd need an ACRO to picatinny adapter.

Regarding the buttons on the side, is it normal for the minus button to have no positive press or click when the plus button has a positive click and sound? Just received mine and going through the manual to see if it's a feature but no info on that.

Asked by: Lunchbocks
No problem, that's by design.

Will this fit and work on a Sig Sauer P320 X-Compact? Do you sell the mount for it to fit on the P320 X-Compact?

These will work on that handgun. The sight will come with an adapter to fit the Docter plate, but you can also use an ACRO footprint plate.

What is the overall height? I see the window height is listed on the spec sheet but not the overall height, I'm trying to determine if this will fit in a Safariland holster for the 509T and Acro.

Asked by: Yaroslav
Thanks for asking! This just measured out to 1.365". (34.69mm). This was *without* the picatinny mount.

I am assuming I need an acro adapter to put this on the accessory rail of the Steiner t536?

Asked by: Gomer

Will the MPS mount on a Staccato P DUO AND also does it have a AR15 mount??

Asked by: Jr9mm
Yes you'll just need an ACRO or Docter mount. There are ACRO to picatinny mounts available for AR use.
