The Perfect Zero Build Kit is an Atlas Gun Works 1911 DS Build Kit — a double-stack 1911 foundation available in three stages. LPWS offers six precision CNC machining services purpose-built for it. This is the complete guide: what the kit is, what each stage includes, and how LPWS turns a blank slide into a finished, one-of-a-kind build.
Perfect Zero is a retailer that sells Atlas Gun Works 1911 DS Build Kits at PerfectZero.co. The Atlas DS is a double-stack 1911-style platform that accepts 2011-style magazines and holds the same fit-and-finish standards as the custom 2011 market. Every kit ships with a blank slide — no serrations, no cuts, no design work applied. That blank slate is exactly where LPWS comes in.
The kits come in three stages. You purchase the kit, source remaining parts as needed, and bring a qualified gunsmith in for final assembly and function testing.
Stage 1 — Raw Atlas DS frame and slide. Your blank canvas. Maximum builder control, maximum gunsmith time required at final assembly.
Stage 2 — Frame and slide plus fitted components: barrel, bushing, and guide rod. Reduces gunsmith hours at final assembly.
Stage 3 — Further fitted internals included. The most complete starting point, with the least final assembly work remaining.
All three stages ship with the same blank slide. All three are fully compatible with every LPWS machining service. The stage you choose affects gunsmith cost and timeline — not your LPWS options.
Close — but not identical. A 2011 typically refers to builds on the Strayer Voigt or STI/SVI platform. The Atlas Gun Works 1911 DS is its own design with distinct tolerances and components, though the practical result for a builder is very similar: a double-stack 1911-style pistol in your caliber of choice.
LPWS has been building and machining 1911-pattern pistols since 2012. The Atlas DS is a platform our team knows precisely — our machining services are specifically calibrated for it.
LPWS machines the blank Atlas DS slide into one of three designs — each with a distinct aesthetic and performance character. Every design is available slide-only or combined with barrel porting.
Deep high-traction knurling with a distinctive top window cut. Maximum grip. An unapologetic look built for the shooter who wants aggressive aesthetics and reliable manipulation under stress. The most distinctive design in the lineup.
Available as slide only — $378.50 or with barrel porting — $428.00.
Strategic lightening cuts reduce reciprocating mass for faster cycling and a flatter shooting experience. Sharp, efficient cocking serrations. Tactical edge without sacrificing utility — built for speed.
Available as slide only — $375.00 or with barrel porting — $425.00.
Refined front and rear serrations in a streamlined, clean profile. Ample grip surface without a busy visual identity. Performance and sophistication in the same package — the choice for the builder who wants results without the aggression.
Available as slide only — $275.00 or with barrel porting — $325.00.
Three designs, each available slide-only or with matched barrel porting. All services are purpose-built for Atlas Gun Works 1911 DS slides from the Perfect Zero kit.

USPSA, IDPA, practical shooting. Ported configurations deliver measurable recoil reduction and faster split times.
Builders who want a one-of-a-kind pistol with a distinct identity. No factory gun looks like a LPWS-machined Atlas DS slide.
LPWS precision results at a lower entry point than a complete build. The craftsmanship, at a different price tier.
Handling your own final assembly? LPWS handles the precision machining. You handle the build.
You want a fully built, tested, ready-to-ship pistol. See the LPWS IslandBoy Variant 11.0 or the Variant 7 configurable build.
Barrel ports not precisely aligned with the slide cuts cause cycling failures under fire. Sending both components to LPWS for matched machining eliminates this risk entirely.
