Work order — CZ 75 B

Taking the firearm apart for a job such as refinishing, and putting it back together to specification. Generated from the Pew-Takedown entry last updated 2026-10-29. Confidence: high.

Shop difficulty: Tier 2 of 3

66 line items (70 pieces) in CZ's family list, fewer for a plain 75 B; a hammer-fired DA/SA with a sear cage seated against spring pressure, a safety detent and spring that fall out, a hammer spring cap tied to the magazine brake spring, and a peened trigger pin whose reinstallation needs a punch holding everything while springs try to fly. Upper Tier 2, near the Tier 3 line. 66 parts (Complete pistol (magazine as one row); our transcribed parts list = single CZ 75-family 'LIST OF PARTS' for all versions in the manual (75 B, B SA, BD, SP-01, P-01 etc.); rows marked * vary by…). Pew-Takedown's rating, not the manufacturer's.

Bench time: strip ~35 min, rebuild ~50 min (estimate). Actual: strip ______ rebuild ______

Special tools:

• Punch set incl. small punch to hold parts while drifting the trigger pin — Trigger pin reinstall
• Pick or toothpick — Lifting the sear spring leg out of the safety-pin groove

Watch for:

• The trigger spring is the hardest part to put back. (reassembly; Northeastshooters.com Forums)
• With the sear block out, the safety detent and its spring can drop out of the side of the frame. (both; Northeastshooters.com Forums)
• The trigger pin is peened into the frame, so the trigger and trigger bar are not easily removed; once out, a punch has to hold everything together while the pin is drifted back and springs fly. (both; Northeastshooters.com Forums)
• The sear cage has to be pushed into its frame rails against spring pressure and held while the safety lever is pushed through to retain it. (reassembly; Apex Gunsmithing)
• CZ sends firing pin (and firing pin block) disassembly to a competent gunsmith. (both; Česká zbrojovka a.s. Uherský Brod)

1. Clear and make safe

1. Point the muzzle in a safe direction and keep your finger off the trigger.
2. Press the magazine release and remove the magazine.
3. Retract the slide fully and lock it open with the slide stop.
4. Visually and physically verify the chamber is empty.
   Tip: The internal rails mean a narrower ejection port. Use a light.
5. Remove all live ammunition from the work area.

2. Disassemble

Field Strip

1. Complete the Clear and Make Safe procedure. The magazine must be out — the manual is explicit that the pistol must not be disassembled with a magazine inserted.
2. If the pistol has a manual safety, shift it to the Safety-Off position so the slide can be worked.
   Tip: Decocker models have no manual safety lever; skip this step on those.
3. Confirm once more that there is no cartridge in the chamber.
   Warning: The manual repeats this check here in capitals. Repeat it.
4. Draw the hammer slightly back and release it so it rests on the half-cock (safety) notch. Everything that follows is easier with the hammer there.
5. Put your left thumb through the trigger guard and grasp the top of the front of the slide with your other fingers. Push the slide slightly back until the two vertical lines on the rear of the frame and slide align.
   Tip: These are the takedown witness marks. If the lines are not aligned the slide stop will not come out.
6. Keeping the lines aligned, push or tap the slide stop out from the right side of the pistol — the base of the magazine works well as a punch — and withdraw it from the left.
7. Pull the slide and barrel forward off the front of the frame.
8. Lift out the recoil spring and guide, then the barrel.
   Warning: The recoil spring is under tension. Keep a hand on it.
9. Stop here. The manual states no further disassembly is needed for routine maintenance, and that firing pin disassembly should be entrusted to a competent gunsmith.

3. Refinish

The components the procedures above separate. Coating, masking and cure are outside this database; follow your coating system's instructions. A part the manufacturer marks "factory fit" should not be swapped or reworked.

The manufacturer's full parts list (66 parts) is on the reference page.

4. Reassemble

Reassembly

1. Set the barrel into the inverted slide and seat it fully forward.
2. Seat the recoil spring and guide in the cut in the barrel lug and press the assembly down into the slide.
3. Start the slide onto the frame rails from the front and push it rearward until the two vertical witness lines align.
4. With the lines aligned, insert the slide stop from the left side and press it fully home.
   Tip: If it will not go, the lines are not aligned or the recoil spring guide is not seated.
5. Release the slide into battery, rack it several times, and perform the function check.

5. Torque

No manufacturer torque values are recorded for this firearm.

Reported by other sources — not the manufacturer

Notes: The manufacturer's documents give no torque value. They say: "CZ 75 P-01 version: Before starting with rear sight windage adjustments it is necessary to loosen the screw securing the rear sight against falling-out. After completing rear sight adjustment procedure it is necessary to tighten the screw back again." (CZ 75 Instruction Manual, PDF p. 23)

Fit or check on rebuild

• Safety detent retracted and sear spring leg in its groove — Both must be in place for the safety to retain the sear cage
• 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

6. Function check

• Verify the pistol is unloaded before each check.
• With the hammer down, press the trigger for a double-action break.
• Cock the hammer, engage the manual safety, and press the trigger. The hammer must not fall.
• Disengage the safety and press the trigger for a single-action break.
• Hold the trigger back, rack the slide, release slowly to feel the reset, and press again.
• Confirm the slide locks open on an empty magazine and the magazine drops free.

If any check fails, the firearm is not safe to fire. Stop and see a licensed gunsmith.
