What people are saying

Testimonials

I’m so satisfied with the results of my initial project that I have now brought two more firearms to IsoTac to work their ‘magic’ on, with another two soon to follow. The IsoTac team is the winning team in my book.

I can’t recommend Jessie and the IsoTac team enough. I am relatively new to the firearm customization game and nailed it with my selection of IsoTac. Jessie was extremely responsive throughout the process and always sought to keep me informed regarding the status of the work being done.

Why modify?

In addition to pure aesthetics and unique designs, IsoTac Arms slide modifications provide practical performance enhancements through advanced optics mounting and slide mass reductions which provide quicker target acquisition and reacquisition, less felt recoil, and reduced shot recovery time.

01 Optic Cuts

Reflex cuts (optic cuts) are required to add an optic for users that desire more consistent sight acquisition and quicker follow on shots, than that provided by iron sights. Although optic-ready pistols are becoming more common, many pistols produced prior to 2018, do not come “optics-ready.” IsoTac bridges this gap with our precision machining process that allows the user to mount the optic of their choice.

02 Lightening cuts, barrel reveals and serrations

These are various cuts milled into the pistol slide to increase the speed of the action cycle. Although these are often applied to competition guns, where shooters are judged on their accuracy and time, they are also relevant to target shooting and non-competitive shooting. Most modern pistols come standard with rear sight serrations, which help you grip the slide to manually pull it rearward. However, some shooters prefer serrations near the front sights as well. Our designs enhance the functionality, performance and appearance of the factory slide.

03 Ported barrels

IsoTac provides specifically designed porting to pistol barrels which allows expelled gases to escape through the ports resulting in less muzzle flip and felt recoil which lead to faster, more accurate shooting.

04 Coatings and finishings

IsoTac Arms provides a range of colors and finishes for your pistol. We customize your slide for a personal touch with Cerakote and laser etching and engraving. We also provide enhancements to the grips including stippling, trigger guard memory cuts and other custom effects.
