Does the Trijicon RMR Type 2 Red Dot Sight fit on a standard slide?

The Trijicon RMR Type 2 3.25 MOA Red Dot Sight will only fit on a standard slide if that slide features a pre-milled dovetail and sufficient physical clearance for the optic’s height.

The Trijicon RMR Type 2 features a 1x magnification and a 3.25 MOA reticle, weighing only 1 ounce. Because this is an optic that sits on top of a slide, ensuring the slide has enough clearance is vital to prevent “slide bite” or interference with the ejection port during cycling. We selected the Trijicon RMR Type 2 for our comparison because it serves as a primary industry benchmark for durability. You must verify that your slide’s dovetail width matches the RMR footprint; if the widths differ, you will need a conversion plate or a custom milling job. Additionally, check that the slide material can withstand the mounting pressure required to secure the device without stripping the threads or deforming the metal.

Checklist for Trijicon RMR Type 2 Compatibility

Confirm these physical requirements before purchasing to ensure the optic mounts correctly to your firearm.

• Verify the slide has a pre-milled dovetail rather than a flat surface.
• Measure the dovetail width to ensure it matches the RMR footprint requirements.
• Check the vertical clearance to ensure the optic does not block the ejection port.
• Confirm there is enough internal space for the recoil spring and barrel to move freely.
• Identify if your specific slide requires a separate adapter plate to bridge the footprint.

Comparing the Trijicon RMR Type 2 to Other Options

The Trijicon RMR Type 2 is a rugged red dot sight, which is a small glass optic that puts a glowing dot on a lens to help you aim faster. This specific model is designed for users who prioritize a proven, durable footprint and a compact 1-ounce weight. If you require a different reticle size or a different mounting standard, you might look at other options in the category. Buyers who need a lower profile or a different illumination style should look at alternatives that offer different height specifications or different mounting interfaces.

If you own a slide that already features a compatible RMR footprint and you require a durable, lightweight optic for reliable performance, you should choose the Trijicon RMR Type 2.
