5.3 Malfunction Clearing, Low-Light Shooting & Range Qualification

5.3 Malfunction Clearing, Low-Light Shooting & Range Qualification

Quick Answer: Firearm stoppages are remediated through two standardized procedures: Phase 1 (Immediate Action: Tap, Rack, Assess) for failures to feed, failures to fire, and out-of-battery slides; and Phase 2 (Remedial Action: Lock slide, strip magazine, rack slide three times, insert fresh magazine, rack, assess) for complex double feeds and stovepipes. In low-light operations, Positive Identification (PID) is mandatory using techniques like Harries, Chapman, or FBI flashlight holds. Under 37 Pa. Code § 21.19(3)(i), Act 235 candidates must attain a minimum score of 75% in the firearms module; the PSP does not publish the course of fire, and a candidate who fails must repeat the entire module before the approval to train expires.

Stoppage Remediation & Malfunction Clearance Protocols

In armed combat encounters, a firearm stoppage turns a lethal weapon into an inert metal club. Armed security officers must diagnose and clear mechanical stoppages instinctively through muscle memory without looking down at the weapon.

+-------------------------------------------------------------------------+
|                  STOPPAGE CLASSIFICATION & DIAGNOSTICS                  |
+-------------------------------------------------------------------------+
| CLASS 1 / FAILURE TO FIRE OR FEED (Immediate Action / Phase 1):         |
|   - Misfire / Dud Primer, unseated magazine, or slide out of battery.   |
|   - Symptom: Click instead of bang, or trigger dead with slide forward. |
|   - Remedy: TAP - RACK - ASSESS.                                        |
+-------------------------------------------------------------------------+
| CLASS 2 / STOVEPIPE EJECTION FAILURE (Phase 1 or Phase 2):              |
|   - Spent casing caught vertically in ejection port by closing slide.   |
|   - Remedy: Immediate sweep or TAP - RACK - ASSESS.                     |
+-------------------------------------------------------------------------+
| CLASS 3 / DOUBLE FEED / FAILURE TO EXTRACT (Remedial Action / Phase 2): |
|   - Spent casing stuck in chamber while slide tries to feed fresh round.|
|   - Symptom: Slide locked partially out of battery, spongy trigger.     |
|   - Remedy: LOCK - STRIP - RACK 3X - RELOAD - RACK - ASSESS.            |
+-------------------------------------------------------------------------+
| CLASS 4 / SQUIB LOAD (CRITICAL SAFETY STOPPAGE):                        |
|   - Defective powder charge traps bullet in barrel.                     |
|   - Symptom: Muffled 'pop', reduced recoil, smoke from ejection port.   |
|   - PROTOCOL: CEASE FIRE IMMEDIATELY. DO NOT CYCLE OR SHOOT AGAIN.      |
+-------------------------------------------------------------------------+

Phase 1: Immediate Action (Tap, Rack, Assess)

Immediate action is performed instantly whenever the weapon fails to fire ("click" instead of "bang") or suffers a simple feed stoppage:

1. TAP: Use the heel/palm of the support hand to forcefully smack the bottom baseplate of the magazine upward into the magwell, ensuring it is fully locked.
2. RACK: Grasp the top serrations of the slide with an overhand support-hand grip, aggressively rack the slide all the way to the rear while canting the ejection port downward toward the ground (allowing gravity to assist clearing), and release the slide completely (do not ride it forward).
3. ASSESS: Bring the weapon back up onto the target, assess whether the threat persists, and evaluate the decision to fire.

Phase 2: Remedial Action (Lock, Strip, Rack, Reload, Rack, Assess)

Remedial action is required when Immediate Action fails to resolve the stoppage, most commonly during a Double Feed (where two cartridges/casings are wedged into the chamber simultaneously):

1. SEEK COVER / MOVE: Immediately move offline or take cover behind ballistic shelter.
2. LOCK: Pull the slide fully to the rear and manually engage the slide stop lever upward to lock the slide open.
3. STRIP: Depress the magazine release catch and forcefully rip/strip the magazine out of the grip frame with the support hand (a double-feed magazine will not drop free on its own). Discard the compromised magazine to the ground.
4. RACK THREE TIMES: Vigorously cycle the slide back and forth three times with the overhand grip to shake free and eject the stuck cartridge or extracted casing from the chamber.
5. RELOAD: Reach to the duty pouch, retrieve a fresh, loaded magazine, and insert it firmly into the magazine well until seated.
6. RACK: Rack the slide to chamber a live cartridge.
7. ASSESS: Re-acquire the threat and assess the need for deadly force.

The Squib Load Danger

A squib load occurs when an ammunition cartridge lacks sufficient gunpowder propellant. The primer ignites, generating just enough pressure to push the projectile out of the case into the barrel rifling, where it lodges firmly midway down the bore.

• Symptoms: An abnormally quiet, muffled "pop" sound instead of a loud gunshot, accompanied by virtually zero recoil and smoke venting from the ejection port/action.
• Fatal Hazard: If an officer cycles the action and fires another round behind a bore obstruction, the catastrophic pressure spike will rupture the barrel and slide, causing severe cranial/hand trauma and destroying the weapon.
• Protocol: Never rack and fire after a muffled pop. Holster/safe the weapon, unload completely, and use a brass clearing rod to push the lodged bullet out of the barrel from the muzzle end.

Low-Light Operations & Tactical Flashlight Holds

Statistically, over 70% of armed encounters occur in conditions of low light or darkness. In low-light environments, armed security officers must balance the legal imperative of Positive Identification (PID) with tactical light discipline.

+-------------------------------------------------------------------------+
|                  TACTICAL FLASHLIGHT EMPLOYMENT HOLDS                   |
+-------------------------------------------------------------------------+
|  HARRIES TECHNIQUE:                                                     |
|    - Flashlight in support hand, crossed under shooting wrist.          |
|    - Backs of hands press together firmly for isometric stabilization.  |
|    - Advantage: Light tracks perfectly with firearm muzzle.             |
+-------------------------------------------------------------------------+
|  CHAPMAN TECHNIQUE:                                                     |
|    - Flashlight held like a pen/sword; thumb and index grip light tube. |
|    - Remaining 3 support fingers wrap over shooting hand in 2-hand grip.|
|    - Advantage: Familiar two-handed shooting feel.                      |
+-------------------------------------------------------------------------+
|  FBI TECHNIQUE:                                                         |
|    - Flashlight held in support hand extended high and away from torso. |
|    - Advantage: Draws adversary's return fire away from officer's body. |
|    - Disadvantage: Forces single-handed shooting platform.              |
+-------------------------------------------------------------------------+

Positive Identification (PID) & Flashlight Principles

• Positive Identification (PID): Under PA Title 18 Chapter 5, an officer cannot legally use deadly force against a shadow or unverified shape. The officer must positively identify a deadly weapon, aggressive intent, and target isolation before firing.
• Intermittent Illumination: Never leave a flashlight continuously illuminated while moving; this acts as a homing beacon for hostile gunfire. Use brief, intermittent 1-to-2 second flashes of light ("flash, evaluate, move, illuminate").
• Weapon-Mounted Lights (WML) vs. Handheld Lights: While WMLs provide exceptional two-handed recoil control in low light, a weapon-mounted light is NOT a search tool. Searching for lost keys or inspecting IDs with a WML violates Rule 2 (lasering non-threats). Handheld lights are mandatory for general administrative navigation and searching.

Act 235 Range Qualification: What Is Actually Published

This is an area where prep material routinely invents detail, so separate what the regulation says from what it does not.

What 37 Pa. Code § 21.19(3)(i) says

"To successfully complete the required training program, an applicant must attain a minimum score of 70% in the academic module and, if applicable, 75% in the firearms module."

That sentence is the entire published standard for the range. Section 21.19 does not specify a round count, distances, stages, time limits, target type, or scoring rings, and the Pennsylvania State Police do not publish the course of fire. The Commissioner prescribes it and certified schools administer it under certified firearms instructors.

Do not memorize a "50-round Act 235 course." Third-party sites often reprint the MPOETC 50-round handgun qualification course — that is the standard for municipal police officers under Act 120, not the Act 235 privately-employed-agent course. Confusing the two is a real exam trap, and the safe answer to "what is the Act 235 firearms standard?" is 75% in the firearms module.

What certified schools do publish

Schools publish their equipment and ammunition requirements, and these are consistent enough across providers to be worth knowing before you enroll:

Two published range rules matter more than any course-of-fire trivia:

• Physical demand: at least one timed stage requires kneeling and rising unassisted. Candidates who cannot do that safely will not pass.
• Safety is pass/fail on its own: an accidental discharge or an unsafe range incident that gets a student dismissed from the range is scored as a failure of the firearms portion, no matter how the paper target looks.

Failure and re-testing (§ 21.19(3)(ii))

There is no "one immediate remedial attempt" in the regulation. An applicant who does not successfully complete a module "shall be permitted to re-enroll in that training module which he failed," but only if the re-enrollment happens before the Commissioner's approval to attend training expires, and the applicant "must repeat the entire training module which he previously failed and attain a successful score." If the approval lapses first, § 21.19(4) requires a brand-new application under § 21.13. Renewal candidates face the same 75% firearms standard plus a 70% academic renewal standard under § 21.24(c).

Scenario: The Double Feed Stoppage Under Attack

Incident: During a nighttime armed robbery at an armored car pickup, an armed guard is fired upon by an armed robber. The guard draws, fires one shot, and attempts a follow-up shot, but the trigger feels mushy and the slide is slightly open. The guard looks and sees a double feed (a spent casing wedged in the chamber with a live cartridge jamming behind it).

Tactical Analysis:

• Failure of Phase 1: If the guard simply executes Tap-Rack-Assess, the slide will jam the two cartridges even tighter into the breach face, worsening the stoppage.
• Correct Execution of Phase 2:
  1. The guard immediately steps laterally behind the armored vehicle's engine block (ballistic cover).
  2. The guard locks the slide rearward using the slide stop.
  3. The guard depresses the mag release and forcefully rips the magazine from the well.
  4. The guard works the slide back and forth three times, clearing the chamber.
  5. The guard grabs a fresh magazine from the duty belt, inserts it firmly, racks the slide, drives out from cover, and re-engages the threat.

Exam Tip: Malfunction Remediation, Squib Loads & Qualification Passing

• Double Feed = Lock, Strip, Rack, Reload: On the Act 235 written exam, remember that a double feed cannot be cleared by Tap-Rack-Assess. It requires the full Phase 2 Remedial Action protocol (Lock slide, Strip magazine, Rack 3 times, Reload fresh mag, Rack slide).
• Squib Load Rule: A muffled sound with reduced recoil is a squib load—the absolute rule is to cease fire immediately and inspect the bore; never fire another round.
• Passing Score: 37 Pa. Code § 21.19 mandates a minimum score of 75% (38 of 50 hits) on the live-fire qualification.
