Hudson Manufacturing, makers of the rather unusual and innovative Hudson H9 pistol, has begun shipping their new drop-in H_RD slides for those who pre-ordered the product. Introduced and made available for pre-order about three months ago, the H_RD slides each feature a special pistol red dot sight cut and a patented adapter plate to allow the mounting of specific pistol red dot sights. To date, the available H-RD slides accommodate the Shield RMS, Trijicon RMR and the Leupold Deltapoint Pro.

In their online shop, Hudson Manufacturing describes the H_RD slide in more detail:

The H_RD slide is a variant of the H9 slide engineered to allow for the optimized mounting of red dot optics. The patent pending H_RD slide mounting plate system allows a single slide to use multiple optics. Initially, Hudson Mfg is offering a choice from three machined, steel mounting plates for:

Trijicon RMR

Shield RMS

Leupold DeltaPoint Pro

Every H_RD slide will ship with an anodized aluminum block-off plate for use when an optic is not mounted. The H_RD features a suppressor height front sight to use with the integrated back-up rear sight on the RMS, the optional rear sight on the DeltaPoint Pro, or the integrated suppressor height rear sight on the RMR mounting plate.

The hardened steel mounting plates fit over a robust pivot surface and rotate securely into cuts in the slide. The result is a robust system that prevents forward and rearward motion of the plate and provides the assurance that the H_RD plates will keep your optic in place while shooting. The H_RD slide is engineered to allow for the lowest possible mounting surface without sacrificing weight, reliability, or compromising critical features.

If you find yourself running more than one variant of these fine red-dot optics, additional mounting plates are available separately.

The MSRP for an H_RD slide is currently pegged at $747. A Trijicon RMR costs around $468, a Shield RMS $400 and a Leupold Deltapoint Pro should be around $519. Prospective and current owners of the Hudson H9 seeking to upgrade their pistol to have these red dot sights should expect to shell out between $1215 to $1266.

Given these prices, do you think it’s worth the extra cash to convert your Hudson H9 into a tactical-style pistol, or are you hoping another aftermarket outfitter will come along and offer a less costly (but hopefully just as effective) option? Tell us what you think in the comments!
