The capstone: how to live with a C96 once it’s built or bought, and a one-stop quick reference to laminate for the bench. Legal specifics are Vol 11; this is the day-to-day.

12.1 Range use (9×19)

  • Ammo: standard-pressure 9×19 only. No +P / +P+ in a vintage action or a freshly fabricated one without formal proof testing (Vol 3 §3.5). The locked-breech action is fine at standard pressure (~35k psi, near the 7.63’s ~30k).
  • First firing of a build: verify headspace (go/no-go) and lockup, then proof/break-in remotely (lanyard or rest) before shooting it by hand — standard practice for any first-fire of a fabricated or rebarreled gun (Vols 7–9).
  • Disconnector check: confirm true semi-auto (one shot per trigger pull, crisp reset). A doubling C96 is a malfunction and a legal problem (Vol 6 §6.2, Vol 11 §11.3) — stop and fix.
  • Function: charger-load from the top (or the magazine, on detachable-mag variants); mind the bolt-hold-open on empty and the manual-of-arms quirks (Vol 6).

12.2 Maintenance

  • Takedown is the no-pin interlock sequence (Vol 6 §6.3) — clamp the frame for the mainspring/rocker steps; never force it.
  • Clean the bore and chamber; keep the lockwork lightly oiled; watch the firing-pin spring and extractor (the usual wear/breakage points).
  • Log work and round count per piece in ../00-inventory/{nickname}.md.

12.3 Storage & transport

  • Store unloaded, secured per your jurisdiction; a C&R/antique still warrants safe storage.
  • Transport: follow Vol 11 / state law. Note the shoulder-stock pivot (Vol 11 §11.2) — don’t transport pistol + fitting stock in a way that creates an unintended SBR/constructive-possession situation.
  • Photos stay in ../00-inventory/photos/ until you choose to share them (../../_shared/legal_ethics.md).

12.4 Cheatsheet — laminate this

Variant ID (read the hammer first): spur (proto) → cone (1896–99) → large ring (1899–1904) → small ring (1904+). Then: receiver sides (milled/shallow/flat), barrel length, chamber marking, safety type, caliber tells. (Vol 4)

Dating (approx., verify in a reference): “SYSTEM MAUSER” earliest → “WAFFENFABRIK MAUSER OBERNDORF” from ~360 → flat-side/large-ring ~15k (1899) → Bolo ~29k → small-ring/6-groove ~40k → 9mm Export 40–80k → “Ns” safety ~200k (1912) → Red 9 1916 → 1920 reworks → banner/post-war ~600k → M30 ~800k. ~1M total. (Vol 5)

Dimensions (verify before machining): OAL 312 mm (5.5″) / 271 mm (Bolo); barrel 140 mm std (Bolo 99 mm); weight ~1.13 kg; bore .3008″ (7.63) → .355″ for 9×19; rifling 6-groove RH (4-groove early). (Vol 6, ../blueprints/README.md)

Cartridge: 7.65 Borchardt (proto) → 7.63×25 (classic) → 9×25 Export → 9×19 Red 9 = our build (mouth-headspacing, standard frame/mag). No +P. (Vol 3)

Build paths: A authentic specimen (usual right answer) · B parts kit (receiver-provenance law) · C from scratch (very high skill; lockwork hand-fit; barrel farm-out; 100–300+ hr). (Vols 7–9)

Build must-haves: disconnector geometry (or it’s full-auto) · takedown-latch/hammer interlock (safety) · 9×19 chamber/feed (not scaled 7.63) · own serial only, no counterfeit Mauser marks. (Vols 6, 9, 10, 11)

Legal pivots: pre-1899 = antique / post-1899 = C&R (boundary variant-specific) · stock = SBR (narrow 2014 C&R exemption for original stock + C&R gun) · Schnellfeuer = machine gun (never build/convert) · home manufacture: federal personal-use, state may require serialization or forbid — confirm. Not legal advice. (Vol 11)

12.6 What’s next for this build

This series is the reference; the physical build is future work. When a specimen or scratch build begins, register it in ../00-inventory/ and log progress in ../builds/{slug}/. Photo gaps to fill (Wikimedia Commons via the Photo Helper): C96 variant reference shots (cone/large-ring/small-ring/Bolo/Red 9), markings close-ups, and a takedown sequence — to supplement the patent line drawings already embedded.
