What Optic is Compatible with my Slide?
At McCluskey Arms Co., we specialize in custom optic cuts to help shooters elevate their firearms. Whether you're a competitive shooter, concealed carrier, or tactical professional, choosing the right optic and footprint for your firearm can significantly enhance accuracy, speed, and target acquisition.
Optic cuts allow us to machine the slide of your firearm to accept a red-dot optic directly, eliminating the need for clunky adapters. This seamless integration maintains your firearm’s sleek profile while giving you superior performance in high-pressure environments.
Which Optics are Compatible with my Slide?
When deciding which optic is best for your needs, it's important to consider the specific footprint that matches your firearm model. Below, we provide a breakdown of popular firearms and the optics we can customize them for. This list includes details on iron sight configurations—whether you prefer to retain forward irons, rear irons, or opt for no irons at all.

Irons Position Options
Each slide/footprint combination allows for one or several irons positions. Not all combinations work with each irons position.
When choosing an optic cut, it's essential to decide on the placement or removal of iron sights, depending on your needs.
Forward Irons: Positioned in front of the optic, they allow co-witnessing, giving you a backup aiming solution if your optic fails. This is ideal for tactical and self-defense scenarios.
Rear Irons: These provide a traditional sight alignment but can partially obstruct the optic’s view.
Delete Irons: A clean, streamlined look with no obstruction, great for shooters relying solely on the red dot for quicker target acquisition.
