Precision direct-milled optic cut for the full-size Tanfoglio platform, built for competition-grade durability and a low, secure optic mount with no adapter plate. Our cut runs full recoil lugs front to rear for the cleanest, strongest optic interface under high round counts.
This service covers the full-size, large-frame steel slide shared across the Tanfoglio competition lineup — sold under the Tanfoglio, Tanfoglio Defiant, EAA Witness, and IFG brands.
The cut uses full lugs front to rear for the best optic interface and maximum strength in competitive, high-round-count use.
The optic sits low for a faster sight picture. Your slide's internal firing pin block is required for refitting to the new deck height.
We provide a black oxide tool finish on the machined area. This product includes the optic cut only.
This optic cut fits the full-size, large-frame steel slide shared across the Tanfoglio competition lineup (Tanfoglio, Tanfoglio Defiant, EAA Witness, IFG). Confirmed-compatible models include:
Not sure which frame you have? Full-size large-frame guns (.38 Super, .40, 10mm, .45, and most full-size 9mm) all share this slide. Small-frame, compact/Carry, and polymer Stock 3 Polymer models use a different slide — message us with your serial or a photo before ordering and we will confirm.
Choose the cut that matches your optic and your goals:
You can always add a step cut later, but you can't take it away. If you cut for the Holosun 507 Comp now and later want the SRO, we can simply cut the deck down as a service.
Our cuts are built around proven competition red dots:
Our pick: the Holosun 407 Comp or 507 Comp. Their cut keeps the extractor pin accessible without removing the optic, so the slide can be serviced without pulling your red dot — an advantage the SRO cut does not offer.
Pair your optic cut with the gear that makes it shine:
Enclosed-emitter competition dot with a wide window. Our recommended pairing — the cut keeps your extractor pin accessible without pulling the optic.
Open-emitter competition dot with the same wide window and the same extractor-pin access advantage.
A wide-window competition red dot for shooters who prefer the SRO footprint.
Build target focus, dry-fire consistency, and red dot presentation skill with the optic you actually run.
It's not required, but it's better for us to have it so we can reassemble the firing pin block and install the optic over it for shipping — this also ensures the screws are perfect for your optic. We send screws for Trijicon only.
A direct cut lowers the optic, improves mechanical engagement, and removes failure points compared to plate systems.
