First Thoughts on the LEU D-POINT MNT KIT MT SIG 226

The LEU D-POINT MNT KIT MT SIG 226 from Leupold offers a seemingly simple solution: a dovetail base designed to mount a DeltaPoint Pro directly onto a Sig Sauer P226. This eliminates the need for milling the slide, providing a potentially faster and more cost-effective way to add a red dot optic. I was immediately intrigued, hoping for a robust and reliable mounting system.

My primary motivation for seeking this product was the desire to modernize my aging Sig P226 without permanently altering the firearm. I was looking for a non-destructive, reversible method to test the waters with a red dot sight on one of my favorite pistols. The LEU D-POINT MNT KIT MT SIG 226 promised exactly that.

The initial impression upon unboxing was…underwhelming. It’s a small, black matte piece of metal. The finish looked durable enough, but the lightweight nature made me question its long-term robustness.

I considered other options, namely having the slide milled for a direct mount, or using a universal rail mount that clamped onto the frame. Milled slides are expensive and permanent. Universal mounts often feel clunky and can interfere with the firearm’s ergonomics. The LEU D-POINT MNT KIT MT SIG 226 offered a middle ground – a direct optic mount without permanent modifications.

Initially, I was cautiously optimistic. I hoped the simplicity of the design would translate to ease of installation and dependable performance. I just hoped the light weight wouldn’t be indicative of poor quality.

Real-World Testing: Putting LEU D-POINT MNT KIT MT SIG 226 to the Test

First Use Experience

My initial testing occurred at my local shooting range. I installed the LEU D-POINT MNT KIT MT SIG 226 onto my Sig P226, mounted a Leupold DeltaPoint Pro, and zeroed the optic at 15 yards. The conditions were sunny and dry.

Installation wasn’t as smooth as I’d hoped. The dovetail was extremely tight, requiring a significant amount of hammering (with a proper nylon punch, of course) to get it seated. Once mounted, however, the DeltaPoint Pro felt secure. The initial groups were promising, staying within a 2-inch circle. However, after about 50 rounds of 9mm, I noticed a slight shift in zero.

Extended Use & Reliability

After several range sessions and approximately 500 rounds, the LEU D-POINT MNT KIT MT SIG 226 has shown both strengths and weaknesses.

The mounting base has remained secure in the dovetail after the initial installation. However, the zero shift I observed initially persisted, requiring occasional adjustments, roughly every 200 rounds. This is unacceptable for serious use, but might be okay for casual range use. There are no major signs of wear and tear on the base itself.

Maintenance is simple: just wipe it down with a lightly oiled cloth after use. Compared to a direct-milled slide, which offers superior zero retention and stability, the LEU D-POINT MNT KIT MT SIG 226 is a compromise. It provides a red dot capability, but sacrifices some precision.

Breaking Down the Features of LEU D-POINT MNT KIT MT SIG 226

Specifications

Type: Base. This is a dovetail adapter that replaces the rear sight.
MFG/Model: Sig Sauer P226. It’s specifically designed for this model.
Style: Dovetail. This mounting style requires fitting into the existing dovetail cut for the rear sight.
Finish: Black Matte. The finish provides a non-reflective surface.

These specifications are important because they determine compatibility and mounting style. The P226-specific design ensures a (hopefully) snug fit. The dovetail style means no permanent modifications are needed, but can introduce some shift if not properly fitted.

Performance & Functionality

The LEU D-POINT MNT KIT MT SIG 226 allows for mounting a DeltaPoint Pro on a Sig P226 without slide milling. This provides a pathway to red dot sights for those who prefer reversibility. The primary weakness is the potential for zero shift, which impacts accuracy and reliability.

It partially meets expectations. I wanted a non-permanent solution, and it delivers on that. However, the zero shift issues detract significantly from its overall utility.

Design & Ergonomics

The black matte finish is aesthetically pleasing and doesn’t add significant bulk to the pistol. The lightweight design is a double-edged sword. It prevents adding excessive weight, but it might compromise rigidity. The installation, while theoretically simple, required significant force.

It adds height to the optic compared to a direct-milled slide. This can affect the cheek weld and sight picture.

Durability & Maintenance

The LEU D-POINT MNT KIT MT SIG 226 seems reasonably durable, showing no signs of structural failure after repeated use. Long-term durability remains to be seen.

Maintenance is simple, requiring only occasional cleaning and inspection. No special tools are needed beyond those required for basic firearm maintenance.

Accessories and Customization Options

The LEU D-POINT MNT KIT MT SIG 226 doesn’t directly support accessories beyond the intended DeltaPoint Pro. However, its compatibility with the Sig P226 means it works with standard P226 holsters.

There are no directly compatible accessories for the mount itself. The DeltaPoint Pro is the only optic it’s designed to accept.

Pros and Cons of LEU D-POINT MNT KIT MT SIG 226

Pros

Reversible installation, no permanent modifications to the firearm.
Relatively inexpensive compared to slide milling.
Simple design and easy maintenance.
Allows for quick attachment of a DeltaPoint Pro.
Maintains compatibility with most standard P226 holsters.

Cons

Potential for zero shift, impacting accuracy.
Dovetail installation can be difficult, requiring significant force.
Adds height to the optic, potentially affecting sight picture.

Who Should Buy LEU D-POINT MNT KIT MT SIG 226?

Perfect for: Those who want to experiment with a red dot sight on their Sig P226 without permanent modifications, and who are willing to accept some potential zero shift. It could be useful for casual range use, or for those who want a quick and easy way to try out a DeltaPoint Pro before committing to a more permanent solution.

Who should skip this product? Anyone who demands absolute precision and reliability, such as competitive shooters or those using their firearm for self-defense. If zero shift is unacceptable, opt for slide milling.

Must-have accessories or modifications? A high-quality nylon punch for installation, a thread locker to secure the mounting screws for the optic, and vigilant monitoring of the optic’s zero.

Conclusion on LEU D-POINT MNT KIT MT SIG 226

The LEU D-POINT MNT KIT MT SIG 226 is a mixed bag. It provides a reversible and relatively inexpensive way to mount a DeltaPoint Pro on a Sig P226, but it comes with the potential for zero shift, which diminishes its utility for serious applications.

The price of $31.49 is justifiable for experimentation. The true value lies in its reversibility.

Personally, I would hesitantly recommend it. Only to those who understand its limitations and are willing to accept the potential for zero shift. I would strongly suggest considering slide milling for a more reliable and accurate solution. It’s a decent option for dipping your toes in the red dot world. But for serious use, look elsewhere.
