How to mount a red dot sight on HS H11 Pro RDR

About HS

HS Produkt, a Croatian firearms manufacturer, was established in 1991. Initially named IM Metal, the company underwent a rebranding in 2001, adopting its current name following the notable success of their HS2000 series of semi-automatic pistols. The company has a strong presence in the United States market, where Springfield Armory, Inc. distributes several of their firearms under various brand names including Hellcat, XD, and Echelon. Notably, about ninety percent of HS Produkt’s firearms are exported to the U.S., underlining the significant demand and popularity of their products in the American firearms market.

About HS H11 Pro RDR

The H11 Pro RDR is a mid size micro-compact pistol from Croatian manufacturer HS Produkt. It features a polymer frame and a hammer-forged barrel. This single-action, striker-fired pistol is distinguished by its high magazine capacity, holding 15 rounds in a double-stack magazine, a significant enhancement over the non-Pro version which has a magazine capacity of 11 rounds. This increased capacity is a notable feature for a pistol this size. In the box, you also get a 17-round extended magazine. HS H11 Pro RDR incorporates both a trigger safety and a firing pin safety, along with a loaded chamber indicator. The grip’s texture is akin to fine-grit sandpaper, ensuring a firm hold. Its sighting system includes a fiber optic front sight and a dovetailed rear U-notch sight, enhancing aiming precision. Compared to the non-Pro model, this pistol is longer and heavier, weighing 595 grams without the magazine, measuring 167.5 mm in length, and featuring a 94 mm barrel. Its size and weight remain sufficiently low to make it suitable for concealed carry. The HS H11 Pro RDR includes two Picatinny slots located underneath the front part of the pistol, designed for the attachment of accessories. The pistol can handle the +P ammunition, but it is important to follow the manufacturer’s safe use guidelines.

In the US market, this pistol is distributed by Springfield Armory, Inc. as the Hellcat Pro.

The gun is available in the 9×19 caliber.

The HS H11 Pro RDR is offered in two colour variants:

  • Black
  • FDE

Each colour variant is available with or without a threaded barrel. Models featuring threaded barrels are silencer compatible.

HS H11 Pro RDR is optic ready.

  • HS H11 Pro RDR, black version without the threaded barrel
  • HS H11 Pro RDR, black version without the threaded barrel, FDE version (source: netgun.pl)

  • I have a fairly new shop and am starting to get into handgun red dots. I have enjoyed the articles you I have that I have seen.
    I have checked out your articles on mounting red dot sites, but for the life of me I can’t find where you actually show or even explain you ting process. I understand it should be self explanatory but it would be nice to see an article or video on the actural mounting on any handgun so people and see it done correctly.
    Anything you can do would be appreciated.
    Keep up tge Great Work! We are paying attention!

    • Dear David,

      David, thank you for your kind words.

      The primary goal of these articles is to offer detailed information on cuts and plates, as such specifics are hard to come by elsewhere with the same level of detail.

      It is, of course, in our plan to provide video material as well. Stay tuned!
