Specifications

Model-specific safety

• The APX uses a removable serialised chassis, so the serialised component is internal rather than the polymer grip frame. Handling the chassis is legally handling the firearm.
• Confirm from your manual whether your variant requires the striker to be deactivated before the slide comes off — the APX has a striker deactivation feature and the procedure differs from a simple lever rotation.
• The recoil spring assembly is under tension when the slide is off.
• The full-length slide serrations run the whole length of the slide. They grip well and they also abrade holsters and hands.

Under spring tension

• Recoil spring assembly

Shop difficulty

Shop tier 2 Tier 2 — moderate among pistols, for the full job: strip to the parts that get coated and put it back together working. 54 line items in Beretta's APX A1 list, above the Glock range; a punch-only chassis gun but with several small snags: a magazine catch under heavier spring pressure that can fly, a sear spring that snags while the sub-frame goes back in, a fiddly striker end-plate plunger, and a stiff stamped sub-frame to pry open. Easy for Tier 2.

Parts: 53 numbered parts (Complete pistol incl. magazine and S/M/L backstraps; the parts list on this page = 'Parts Listing' (list p. 48, exploded view p. 49), full-size APX A1 in one caliber; 54 pieces), from Pistol User Manual APX A1 (MAN0011 01) — Beretta USA / Fabbrica d'Armi Pietro Beretta S.p.A., p. 48–49 dam.beretta.com [2].

Bench time: about 20 min to strip, 30 min to rebuild (estimate). Estimate for an experienced tech with the right tools, detail strip to coatable parts (slide internals, frame pins, trigger group, sights) and rebuild to a function-checked gun; scale used across pistols: Glock-pattern 15/20 min, other strikers 20-30/25-40, DA/SA hammer guns 30-35/45-50, Hi-Power, Colt 1903 and Mark 23 40-45/60-75. Chassis gun;

Small parts: 7 pins, 11 springs, 2 detents or plungers (counted from the manufacturer's parts list (one per key number unless a quantity is given))

What comes off for coating

• Slide: slide end plate, striker assembly and return spring, striker block and spring, extractor, plunger and spring, front sight, rear sight — punch, Beretta APX sight tool
• Barrel: barrel, recoil spring assembly
• Grip frame / chassis: takedown lever, rear chassis pin, chassis (sub-frame), slide stop pin and slide stop, trigger pin and trigger/slide stop spring, sear assembly, magazine release, plunger, pin and spring, backstrap — punch, brass hammer handle to spread sub-frame

Special tools

• Beretta Sight Adjustment Tool for APX (800J18) — Dovetail sights (manufacturer recommendation)
• Small punch — End-plate locking plunger, chassis pins, magazine release pin

Known pain points

• The magazine catch on the full-size APX is under more spring pressure than the Carry's and can fly off when its lock pin is pushed out. (both)
  Source: Disassembly Guide: Beretta APX A1 (Full Size) — Apex Gunsmithing apexgunsmithing.com [3] — “Be aware that unlike the Carry, there's more spring pressure on it and it could fly off if you aren't careful!”
• When the sub-frame goes back into the grip shell, the hook end of the sear spring gets trapped or crushed unless it is held out of the way. (reassembly)
  Source: Disassembly Guide: Beretta APX A1 (Full Size) — Apex Gunsmithing apexgunsmithing.com [3] — “Before you fully seat the sub-frame into the grip shell, watch that the hook end of the sear spring doesn't get trapped or crushed into the grip shell.”
• The slide end plate needs the captive striker spring held out of the way while its locking plunger is pushed in with a punch. (both)
  Source: Disassembly Guide: Beretta APX A1 (Full Size) — Apex Gunsmithing apexgunsmithing.com [3] — “You need the neon green captive striker spring out of the way and to push the locking plunger in with a punch. It's fiddly, but not super difficult thankfully.”
• Reinstalling the chassis requires checking that the cocking lever spring leg has caught the groove of the rear chassis pin. (reassembly)
  Source: Pistol User Manual APX A1 (MAN0011 01) — Beretta USA / Fabbrica d'Armi Pietro Beretta S.p.A. dam.beretta.com [2] — “Check that the cocking lever spring leg has engaged the groove of the pin”
• The dovetailed steel sights are to be moved with Beretta's dedicated APX sight tool. (both)
  Source: Pistol User Manual APX A1 (MAN0011 01) — Beretta USA / Fabbrica d'Armi Pietro Beretta S.p.A. dam.beretta.com [2] — “it is recommended to use the tool (Beretta Sight Adjustment Tool for APX 800J18) specifically developed by Beretta for replacement”

Fit or check on rebuild

• Cocking lever spring leg in the rear chassis pin groove — The manual has the tech confirm it by pushing the pin back and checking for movement

• Sear spring position before seating the sub-frame — The spring can rotate and get crushed into the grip shell
  Source: Disassembly Guide: Beretta APX A1 (Full Size) — Apex Gunsmithing apexgunsmithing.com [3] — “Before you fully seat the sub-frame into the grip shell, watch that the hook end of the sear spring doesn't get trapped or crushed into the grip shell.”
• Sight position / re-zero — Drift or pressed sights moved for coating shift point of impact unless witness-marked and returned to the same spot
• Full function check (trigger reset, safeties, slide lock-back, drop of striker/hammer only on trigger) — Standard after any fire-control strip; confirms springs and sears went back correctly

Procedures

Torque specifications

No sourced torque values from the manufacturer are recorded for this firearm. Where a fastener has a specified torque — action screws, scope bases, muzzle devices, barrel nuts — get it from the manufacturer or a gunsmith rather than estimating it.

What the manufacturer does say: The manufacturer's documents give no torque value. They say: "Using the screws, fasten the sight onto the slide using an allen key. Details on different screws and keys are given in the chart." (Pistol User Manual APX A1 (MAN0011 01), PDF p. 43 (Aiming device installation)) "The original screws come with a drop of glue applied; if it could not be enough the use of Loctite® is recommended." (Pistol User Manual APX A1 (MAN0011 01), PDF p. 43)

Materials and factory finish

As stated by Beretta. Prep, masking and cure depend on these; a polymer or aluminium part, a nitrided or anodised finish, and a blued steel part are each a different job. Variants with other finishes may exist — check the maker's page for the exact SKU on the bench.

Parts list

Transcribed from the manufacturer's parts list (Pistol User Manual APX A1 (MAN0011 01) — Beretta USA / Fabbrica d'Armi Pietro Beretta S.p.A., p. 48–49 dam.beretta.com [2]) — 'Parts Listing' of the current APX A1 manual (list p.48, exploded view p.49), full-size APX A1 in one caliber. The original APX manual (C6A123 002, per-caliber rows) and APX Carry A1 manual were not used.. Key numbers refer to the exploded view in that document.

Function check

• Verify the pistol is unloaded with no magazine inserted before each check.
• Rack the slide and press the trigger. The striker should release cleanly.
• Hold the trigger to the rear, rack the slide, then release slowly and confirm the reset.
• Press the trigger again to confirm the striker releases.
• Confirm the slide locks open on an empty magazine and the magazine drops free.

Maintenance

Lubrication points

• Frame rails where the slide rides
• Barrel hood and locking lug
• Outside of the barrel at the muzzle end
• Rear barrel lug where the recoil spring assembly bears

Cleaning notes

Light lubrication only — a thin film on the rails and barrel. Keep the striker or firing pin channel dry and free of solvent, since oil there collects fouling and causes light strikes.

Suggested inspection interval: roughly every 5000 rounds. This is a general guideline, not a manufacturer specification.
