SIG Sauer P211-GTO Slide Assembly – 9mm, SIG-LOC Optic Ready, Fiber Optic, Black (8901995)
This is a factory SIG Sauer complete slide assembly for the P211-GTO in 9mm — the same slide that comes standard on the GTO, with the barrel and MACH3D compensator included. It is a slide assembly only, not a complete pistol (no frame or grip module). SIG part number 8901995. This listing is for the P211-GTO 9mm black optic-ready slide and barrel assembly, part 8901995 only.
What’s Included
- Complete stainless steel slide, matte black finish, with all internal slide parts
- 4.4-inch bull barrel with the MACH3D compensator

- Removable flush-fit optic plate with top-accessible screws
SIG-LOC Optic Ready
The slide is cut for SIG’s SIG-LOC interface and accepts both SIG-LOC PRO and PRO footprint optics. SIG-LOC uses five points of contact between optic and slide to help hold zero under recoil. Optic not included.
Fitment
- Standard 9mm P211-GTO — factory replacement
- Standard 9mm P211-GT5 — upgrade to the GTO slide and compensator
