Work order — Beretta 21A Bobcat

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: medium.

Shop difficulty: Tier 2 of 3

62 line items (72 pieces, inflated by color/sight/grip variant rows) in Beretta's Bobcat list; small, spring-dense frame with a safety spring that flies, recoil springs under tight grip screws, and Beretta does not publish detail-strip instructions. More traps than a Glock, nothing that needs timing or a fixture. 47 parts (Complete pistol incl. magazine; our transcribed parts list = 'Bobcat Parts List' (exploded view p. 32, table pp. 33-34), 72 pieces; variant rows (colors, sights, barrels, grips) under one key are…). Pew-Takedown's rating, not the manufacturer's.

Bench time: strip ~30 min, rebuild ~45 min (estimate). Actual: strip ______ rebuild ______

Special tools:

• Hollow-ground screwdriver fitted to the grip screws — Tight slotted grip screws over the recoil springs
• Small roll-pin punch — Firing pin retaining pin

Watch for:

• The manual safety contains a spring that flies when it comes out, and Beretta keeps its detail-strip procedure to its own gunsmiths. (both; Northeastshooters.com Forums)
• The twin recoil springs sit under the grip panels, whose small slotted screws are tight and strip easily without a precisely fitted screwdriver. (disassembly; SIGforum)
• On the same-system Tomcat, levers and springs pop out when the slide/frame is put back together. (reassembly; SIGforum)
• Beretta itself recommends anything past the field strip go to a qualified gunsmith. (both; Beretta USA)
• The firing pin is retained by a roll pin and needs a roll-pin punch to remove properly. (disassembly; Northeastshooters.com Forums)

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. Press the barrel release lever. The barrel will spring upward and pivot open, lifting any chambered round with it.
   Warning: The barrel is spring-loaded and opens briskly. Keep fingers clear.
4. Remove any cartridge from the exposed chamber and inspect the chamber with a light.
5. Physically confirm the chamber is empty.
6. Remove all live ammunition from the work area.

2. Disassemble

Field Strip

1. Complete the Clear and Make Safe procedure, leaving the barrel tipped up.
2. With the barrel open, pull the slide rearward and lift it up and off the frame rails.
   Warning: The recoil spring is under compression.
3. Remove the recoil spring from around the barrel or its guide, noting its orientation.
4. Stop here for routine cleaning. The barrel does not need to come off the frame.

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 (62 parts) is on the reference page.

4. Reassemble

Reassembly

1. Fit the recoil spring in its correct orientation.
2. With the barrel tipped up, set the slide onto the frame rails and push it rearward and down until it seats.
3. Press the barrel down until it latches fully closed.
   Warning: Confirm the barrel is locked down. A barrel that is not latched must not be fired.
4. Rack the slide several times and perform the function check.

5. Torque

Fit or check on rebuild

• Grips installed before any double-action test — The grips keep the external trigger bar in place; without them the trigger bar can pull away
• 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 with no magazine inserted before each check.
• Confirm the barrel latches down positively and does not move when pressed upward.
• Press the barrel release and confirm the barrel tips up freely.
• With the barrel closed, rack the slide and press the trigger for a single-action break.
• With the hammer down, press the trigger for a double-action hammer fall.
• Engage the manual safety and confirm the trigger is blocked.
• Confirm the magazine seats and releases cleanly.

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