Meprolight USIT Slide Support Block ML40451 – 1 out of 2 models Review

Let’s Talk About Meprolight USIT Slide Support Block ML40451 – 1 out of 2 models

The Meprolight USIT Slide Support Block ML40451 – 1 out of 2 models is a seemingly simple, yet potentially crucial tool for anyone working on pistol slides. Manufactured by Meprolight, this block aims to provide stability and support when making adjustments or modifications. It essentially acts as a third hand, freeing you up to focus on the task at hand.

I was drawn to this product after struggling with slide adjustments on several of my 1911s. Maintaining consistent height and preventing accidental damage during sight installation and removal has always been a challenge. I hoped this support block would offer a more controlled and precise method.

Upon unboxing, my first impression was that of solid, unadorned utility. The block is a compact piece of metal, and the presence of multiple holes on each side speak to versatility in accommodating various slide sizes. The weight feels substantial, indicating decent material quality, although the finish is purely functional, not aesthetically pleasing.

Compared to improvising with makeshift supports like wood blocks or padded vises, the Meprolight USIT Slide Support Block promised a dedicated and potentially safer solution. I previously used a universal pistol jig with mixed results, but its complex adjustability sometimes felt cumbersome. This seemed like a more straightforward approach, though it lacks the fine-tuning capabilities of a full jig.

My initial reaction was cautiously optimistic. The simplicity of the design suggests ease of use, but I wondered how well it would adapt to different pistol models. The lack of padding or surface treatment also raised concerns about potential scratching of the slide finish.

Real-World Testing: Putting Meprolight USIT Slide Support Block ML40451 – 1 out of 2 models to the Test

First Use Experience

I first tested the Meprolight USIT Slide Support Block at my workbench while installing new sights on a Glock 19 slide. The block provided a stable base, preventing the slide from rocking or shifting during the installation process. This was a significant improvement over trying to hold the slide steady with one hand while manipulating tools with the other.

Working in a well-lit environment helped as the block itself is just metal. The block did not interact with the outside elements during the test. Initial ease of use was high; I could get a solid grip on the block in a number of configurations.

My first issue was the potential for scratching. Applying masking tape solved this problem, but this adds an extra step.

Extended Use & Reliability

After several months of occasional use, the Meprolight USIT Slide Support Block continues to perform as expected. The block itself shows no signs of wear or degradation. This speaks to the quality of the metal used in its construction.

Maintenance is virtually non-existent; simply wiping it down with a clean cloth after use is sufficient. It outperforms improvised methods by a wide margin in terms of stability and control. It is less versatile than a full pistol jig but much easier to use for simple tasks.

Specifications

The Meprolight USIT Slide Support Block ML40451 – 1 out of 2 models, manufactured by Meprolight, is designed to support pistol slides during various maintenance and modification tasks.

The specific dimensions and weight are not readily available but the block is compact and heavy enough to remain stable during use. The material is likely steel or a similar durable metal. This ensures longevity and resistance to deformation under pressure. The key specification is the presence of multiple hole configurations, allowing for adaptability to a range of pistol slide profiles.

Performance & Functionality

The primary function of the Meprolight USIT Slide Support Block is to provide a stable and secure platform for pistol slides. This allows for easier and safer manipulation during tasks like sight installation, removal, and cleaning. The block performs this function adequately, providing a noticeable improvement over unsupported methods.

Its strength lies in its simplicity and ease of use. However, its weakness is the lack of adjustability and potential for scratching the slide. It meets expectations for basic support but doesn’t offer the precision or versatility of more specialized tools.

Design & Ergonomics

The Meprolight USIT Slide Support Block features a straightforward, utilitarian design. The build quality appears solid, with no obvious flaws or weaknesses. The weight contributes to its stability but could be a drawback for users who prefer lighter tools.

The absence of padding or a non-marring surface is a significant ergonomic concern. The block is user-friendly in terms of setup; however, extra care is needed to protect the slide’s finish.

Durability & Maintenance

Given its simple construction and robust materials, the Meprolight USIT Slide Support Block should last for many years under normal use. There are no moving parts or delicate components that could break or wear out. Maintenance is minimal, requiring only occasional cleaning.

Accessories and Customization Options

However, users can employ various padding materials, such as masking tape or adhesive felt, to protect the slide finish. While not a direct customization, this allows for adapting the block to different needs. It is generally compatible with any standard pistol slide as long as a suitable hole configuration can be found.
