The C& H Precision SG69-ACRO-ST is a replacement steel slide machined for SIG Sauer P226/P229 pistols that’s been cut and drilled to accept modern mini-red-dot optics (Aimpoint ACRO footprint plus RMR/Holosun hole patterns). Built from steel for increased durability and mass, it replaces your factory slide to provide a stout mounting platform for micro reflex sights and a more robust feel than OEM aluminum slides. The XL variant offers an extended/modified profile for additional clearance or aesthetics.
