Brimstone Gunsmithing has a special program for milling police duty handguns to accept red dot sights. With their CNC Machining capacity, they can do very precise machining quickly while controlling costs. This gives them the ability to provide individual officers and agencies a quick and affordable way to put a red dot on their duty gun.

With prior coordination, they can do the job in two days and over night it back, or for agencies, Brimstone can do large runs and process hundreds of guns. They understand that the officer is probably having to foot the bill for this project out of their own pocket, so whether it’s one officer or it’s an entire agency, it’s the same heavily discounted price. The only requirement is that the firearm is truly a duty gun. Don’t be ‘that guy’ and try to sneak your three gun pistol in under your LEO I.D…


Police officers face tremendous challenges. Their training and gear are put to the test everyday. As technology has advanced, red dot sights, such as the Leupold Delta Point Pro, can help officers keep both eyes open, see their sights while focused on a threat in all light conditions and maintain situational awareness. The costs and wait times for the installation of these sights has kept many agencies stuck in the dark ages with iron sights. Brimstone Gunsmithing wants to help.

The cost includes all tear down and reassembly, including installing new sights if you included them, and it also includes a single color Cerakote of your choice on the slide. This is critical to protect the newly machined surfaces from corroding, but it also allows the officer to get a subtle custom look, as long as your agency approves it.

CNC (Computer Numerical Control) Machining is a process which uses a computer to control machine tools. With CNC machining, the computer can control exact positioning and velocity. The 21st century gunsmiths at Brimstone can write computer programs customized for specific guns and optics.

The real key to their success is their ability to rapidly prototype up a digital model of your firearm, optic, and sight combination, and even send you a picture of how the sights are going to co-witness before they ever start cutting on your slide.

Once the model (CAD) and the machining (CAM) are all proved out digitally, the finished product is cut into your slide to within 0.0005” of the picture they sent you. This is accomplished by using an optical comparator to build an incredibly accurate model of slide, optic, and sights, and then using an $8,000 probe system in the mill to exactly find the surfaces of your slide before cutting starts.

All this technology gives them a great diversity of red dot and firearm options, but Brimstone will always recommend the Leuopld Delta Point Pro. It is one of the all-round best red dots and Brimstone can provide them (also at a heavily discounted rate) if you don’t already have one. Delta Point and Glock are both widely used in law enforcement.

On a standard frame Glock (G17, G19, etc) the Delta Point Pro will not fit between the rear dovetail and the internal safety plunger. Brimstone will machine away the rear dovetail and install the red dot where the rear dovetail was. If your department requires a co-witness with iron sights, they can then machine a dovetail in front of the red dot.

There are three options for dovetails here. Option one, blow out the rear sight and run with just a front sight. That front sight may just be the factory one and it’s just filling the hole, or it may be a suppressor height front sight that you can see through your optic. Some red dots come with a mark or features on the rear which allow you to use your red dot as a rear sight, or you can even paint a line on the rear of your optic as a rough rear sight.

Options two (if you’re running a DPP) Leuopld makes a drop in rear sight that fits in the rear of their red dot. You’ll still need to get a front sight tall enough to cowitness, but there’s no new dovetails needed. To make that work, we move the red dot forward slightly and machine the slide flat behind the red dot.

Option three, we just machine a new Glock dovetail in front of the red dot.

Speaking of, cowitnessing or other sight fitment is not guarantied due to the almost infinite variety of Glock sights. This is where the CAD rendering comes in, especially if you’re running and unusual sight combination that hasn’t already been proven, or if you have specific requirements for how some sights cowitness. Depending on the work involved, there can be an extra charge, but if you NEED it to cowitness in a certain way, it might be worth while.

On some large frame Glocks, there is room to squeeze the red dot in there, so you can keep your rear sight dovetail.

They also offer some slide serration packages and a wide range of other Glock or general gunsmithing work. While the same discounts don’t necessarily apply, it might be worth getting done at the same time. Their website ( has a solid selection number of options listed under Shop > Glock Work. If your agency is so inclined, they can even do custom engraving, although that is quoted on a case-by-case basis.

If you have a duty gun that you want to upgrade to a red dot sight, or if you are modifying duty guns for your agency, contact  for pricing and turn around times. Ask about special pricing for the Leupold Delta Point Pro..

About Brimstone Gunsmithing:

‘Bringing traditional gunsmithing into the 21st century.’

Brimstone seeks to keep that old-world quality, attention to detail, and (the most difficult) the wide range of services that traditional gunsmiths would offer. They are constantly striving to improve quality and consistency, improve communication by allowing customers to follow the project, reduce turnaround times and create an environment where you feel comfortable, even excited, to drop off your prized firearms.

At Brimstone Gunsmithing, they work with a number of law enforcement and military agencies, both on a professional and personal level. Most of the staff is previous military or first responders, and they pride themselves on ‘getting it’ when you have a particular project in mind. At the same time, Brimstone has the industrial scale capacity to handle large, agency sized projects.

The ultimate goal at Brimstone is to provide quality products to their customers which fit their needs and (hopefully) their budget. They can advise which parts need to be premium, which can be left factory, and what needs to be something in the middle. They are gun people, and love helping out.
