Tri-Top Machine Service
Couldn't load pickup availability
Give your slide a clean, low-profile Tri-Top cut for reduced glare, a flatter sight plane, and a race-inspired look. Precision-machined in-house to tight tolerances, the Tri-Top improves sight acquisition while leaving a finished, professional appearance.
What’s Included
-
Precision Tri-Top machining across the slide top (clean edges, smooth transitions)
-
Final inspection and return-ready packing
Finish Options
Choose how you want the slide left after machining: No finish (leave raw) or add a slide finish
Turnaround
-
Tri-Top machining: ~3 weeks (may vary with workload)
-
If adding a finish: combine with finish turnaround (see finish options for estimates)
Overhaul & Fit
-
Only required if you’re sending the complete build.
-
Not required if you’re sending only the slide, or if you’re already purchasing another service in the same order that includes Overhaul & Fit.

Important Notes
-
DLC / PVD / TiN / Hard Chrome finishes are only compatible with steel.
-
We recommend adding a finish for corrosion/wear protection after machining.
Not Compatible With Internally Lightened Slides: Internally lightened slides are not eligible for Tri-Top machining. The Tri-Top cut removes approximately 0.040" of material, and many internally lightened slides do not have sufficient wall thickness to safely accommodate this service. To maintain proper structural integrity and long-term durability, we do not perform Tri-Top cuts on internally lightened slides.
Shipping & Returns
Shipping & Returns
If you order a product from DSC, we will stand by our product and correct/fix an issue if it may arise. Please note, no returns are accepted on custom barrel services/products or used drop-in barrels. Approved returns on new, unused, non-defective products may be subject to a 10% restocking fee.
Return shipping may be required for projects involving complete firearms rather than individual parts to ensure proper insurance coverage during the return shipping process.
DSC Drop In Barrels
DSC barrels are designed for drop-in installation, in conjunction with factory counterparts such as factory slide stop and recoil - we continuously strive to improve the quality of our drop-in barrels as each style and variant is custom-made, hand fitted to shop models, and coated per order.
Turnaround times are estimated to be approximately 5-7 weeks after the initial purchase, though they are subject to change depending on the situation. *Stainless variants may ship sooner, depending on the order.
**In the unlikely event that you experience any issues with installing your barrel, we offer free custom fitting.
