Specifications

Model-specific safety

• The P30 is hammer-fired and ships in several control variants — DA/SA with a decocker, DA/SA without, and LEM (Law Enforcement Modification) with a different trigger behaviour entirely. Identify which you have before handling it, because the function check differs.
• The slide is removed by aligning a takedown notch and withdrawing the locking pin. Do not force the pin.
• The recoil spring assembly is under tension when the slide is off and should not itself be disassembled.

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. About 60 key numbers (107 rows in HK's list are swollen by V1/V3/SV3, calibre and magazine variants). The frame has HK's elbow/leg springs: the trigger return spring is hard enough to fit that a dedicated pliers is sold for it, and the slide's retaining spring under the firing-pin block is a known trap. More than a Glock, short of Tier 3.

Parts: 73 numbered parts (P30 models (9 mm and .40 S&W; V1, V2, V3 and SV3 variant rows) per this page's transcription; 105 rows, 73 distinct key numbers (highest key 60). P30L and P30SK lists omitted.), from Heckler & Koch P30 Series Operator's Manual — Heckler & Koch, p. 38 hk-usa.com [1].

Bench time: about 30 min to strip, 45 min to rebuild (estimate). Detail strip of slide (firing pin, firing-pin block, extractor, sights) and frame (trigger group, hammer, catches); rebuild longer for the elbow springs and the firing-pin block retaining spring.

Small parts: 5 pins, 15 springs, 4 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: firing pin and spring, firing pin block and retaining spring, extractor and spring, rear sight, front sight — roll-pin punches, sight pusher
• Frame: trigger and trigger return spring, hammer and hammer spring, catch / sear group, slide release, magazine release, locking block / axles — HK trigger return spring pliers

Special tools

• HK trigger return spring pliers — Seating the trigger return (elbow) spring
• roll-pin punches (3 mm class) — Extractor, firing pin and magazine release roll pins
• dovetail sight pusher (or brass drift and padded vise) — Removing and refitting dovetailed sights for coating

Known pain points

• The trigger return spring (an elbow spring) is so hard to place that HK specialists sell pliers just for it; without them it takes an extra pair of hands. (reassembly)
  Source: HK Pistol Trigger Return Spring Tool - Pliers (product page) — HK Parts (parts retailer) hkparts.net [5] — “If you've ever attempted to replace the trigger return spring on an HK pistol, you understand how challenging this task can be.”
• A P30 owner names the trigger spring as one of the most difficult steps and says the spring tool takes most of the hassle out. (reassembly)
  Owners report: Sigs vs HK's - Topic — SIGforum sigforum.com [6] — “With the Hk, having the tool for the trigger spring takes a lot of the hassle out installing that, which was one of the more difficult things to do with my P30.”
• In the slide, the retaining spring is held by the firing-pin retaining block in a way the common videos do not show, so it is easy to rebuild wrong. (reassembly)
  Owners report: Sigs vs HK's - Topic — SIGforum sigforum.com [6] — “You need to know how the retaining spring is held in place by the firing pin retaining block. That is NOT explained in any video.”
• HK stops owners at the field strip; anything further is armorer work. (both)
  Source: P30 Series Operator's Manual (9.16.26 FINAL) — Heckler & Koch USA (Heckler & Koch, Inc.) hk-usa.com [2] — “Disassembly of the pistol is now complete. Only an HK certified armorer should disassemble the pistol further.”

Fit or check on rebuild

• Trigger return spring leg orientation — The elbow spring's legs must sit in their notches or the trigger will not reset
  Source: Sigs vs HK's - Topic — SIGforum sigforum.com [6] — “Replacing the trigger rebound spring is another lesson in frustration. NO video shows the orientation of the legs.”
• Function check: trigger reset, sear/striker engagement, safeties — Standard post-reassembly check on any pistol whose fire-control parts were removed; a mis-seated spring shows up here, not on the bench

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: "DO NOT OVER TIGHTEN THREAD PROTECTORS." (P30 Series Operator's Manual (9.16.26 FINAL), PDF p. 11 ("Instructions for use of HK thread protectors"))

Reported by other sources — not the manufacturer

Materials and factory finish

As stated by Heckler & Koch. 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 (Heckler & Koch P30 Series Operator's Manual — Heckler & Koch, p. 38 hk-usa.com [1]) — P30 models (9 mm and .40 S&W; V1, V2, V3 and SV3 variant rows). Omitted: separate P30L list (p.40) and P30SK list (p.42). Exploded view Figure 56 on p.39.. Key numbers refer to the exploded view in that document.

Function check

• Verify the pistol is unloaded with no magazine inserted before each check.
• With the hammer down, press the trigger for a double-action hammer fall.
• Cock the hammer, operate the safety or decocker as fitted, and confirm the expected behaviour.
• Rack the slide and press the trigger for a single-action break.
• Hold the trigger back, rack the slide, release slowly and confirm the reset.
• 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.
