Beretta 92FS Reconditioning Using an Ultrasonic Cleaner
Designed and developed in Italy around the mid-1980s, the Beretta 92 hand gun model is most famous as the standard firearm of the US military. Constructed with an aluminum frame, the Beretta 92 pistol is a short-recoil operated and locked-breech arm. These rugged pistols match their heft and size with sleek design and detailing. The Beretta 92 fire arm comes in different models, finishes, and trigger types, including the Beretta 92, 92S, 92SB, 92FS, 92FS Inox, 92FS Brigadier, 92FS Elite, 92FS compact, and the 92 FS Vertec. Although a suitable weapon, the Beretta 92 hand gun should be regularly cleaned to keep it up to par. To maintain their condition, extend the utility and ensure one’s safety, owners should make sure their Beretta 92 hand guns are clean, inside and out.
If you own or service a Beretta 92FS 9MM Handgun or similar handguns you will definitely appreciate how an ultrasonic gun cleaner can save time and effort when it comes to cleaning and maintaining the weapon. An ultrasonic weapons cleaner is fast, thorough and safe because unlike some solvent washers and aerosol sprays, today’s ultrasonic gun cleaning solution is biodegradable, minimizing disposal problems with spent solutions.

How an Ultrasonic Gun Cleaner Works
Ultrasonic cleaners are used in a wide range of applications to remove virtually any soil or contamination with the power of cavitation action. Cavitation action describes the implosion of billions of minute bubbles in the ultrasonic cleaning solution as they contact all components of your Beretta 92FS Handgun. The bubbles are created by generator-powered ultrasonic transducers bonded to an ultrasonic cleaning tank and typically operate at an ultrasonic frequency of 37 to 42 kHz (37,000 to 42,000 cycles per second).
The imploding bubbles quickly and safely remove grease, powder residues and other contaminants that could interfere with reliable operation of your Beretta 92FS handgun. So tiny are the bubbles that they penetrate minute cracks, crevices and blind holes impossible to reach with conventional hand gun cleaning tools. The ultrasonic weapons cleaner will complete the job in less than 15 minutes. Meanwhile you can attend to other activities.
How to Select and Set Up your Ultrasonic Handgun Cleaner
A bench or table-top ultrasonic cleaner such as the LR617 along with its lubricating pan is ideal for sporting goods shops, servicing departments and the serious hand gun collector cleaning one or two handguns at a time. Whatever the model and size ultrasonic handgun cleaner you use there are steps to take before you start the cleaning operation by following the manufacturer’s operating instructions.
- Fill the ultrasonic weapons cleaner tank to the fill line (or approximately 2/3 full) with water and an ultrasonic cleaning concentrate diluted per manufacturer’s instructions. We recommend CLN-LR215 diluted 1 part to 10 parts of water.
- In the same way, fill the auxiliary lubricating pan with an ultrasonic gun lubricating solution and place it into the ultrasonic cleaner tank. Ready-to-use CLN-LR212 is a good choice. Make certain that the bottom of the lubricating pan is in contact with the cleaning solution.
- Turn on the ultrasonic cleaner and operate the unit for about 30 minutes to drive off cavitation inhibiting entrained air in both the cleaning solution and the lubricating solution. Degassing is complete when bubbles stop coming to the surface. Note that this step must be performed every time you use fresh cleaning or lubricating solutions.
How to Disassemble, Clean and Reassemble your Beretta 92FS Hand Gun
Step 1: Disassembling the Beretta 92FS Handgun
Safety tip! Keep the gun pointed in a safe direction, away from any persons. Remove the magazine, making sure it is empty. Grasp the gun in a safe direction with your fingers away from the trigger. Hold the slide and pull to the rear and check for any round in the chamber. Repeat this process a few times to ensure the chamber is empty. To fully disassemble your Beretta 92FS hand gun, you will have to field strip your firearm and work on the lower assembly. Remove the grips and set this aside.
To remove the magazine catch assembly, simply press unto the magazine in the opposite direction to release the magazine. The assembly should pop right out. Disassembly of the magazine catch assembly needs precaution since the parts may fly out. The assembly is made of the small frame, two sliders, and a spring. Slightly push the sliders and spring out to form a small arc; make sure to guide these parts out as the spring will release tension.
On the Beretta 92FS frame, press unto the disassembly latch button. While pushing this button, move the disassembly latch lever on the other side upwards until it reaches the frame rail. Still pushing unto the disassembly button, pull the latch lever out a bit and further rotate the latch lever. You can now let go of the disassembly button. Remove the latch lever and disassembly button parts including a small spring.
Grips must be removed to take the main spring out. Hold the frame from the top. On a hard non-slippery surface, set the butt of the handle and press the lanyard loop against this surface. While pressing with just enough pressure, slide the headless pin of the lanyard loop off; you can use an allen key to do this. You can now remove the spring and the lanyard loop.
After removing the main spring, you can safely remove the hammer and hammer strut. Take out the hammer pin and the hammer. Upend the frame and the hammer strut should simply fall out.
To disassemble the Beretta 92FS trigger, the trigger bar and slide stop should first be removed. To remove the slide stop, raise the slide stop and slowly jerk the piece out of place. Be careful not to scratch your gun with the slide stop. A spring is attached to the frame but will come out together with the slide stop. Remove this spring from the slide catch.
Take note that grips must be removed to take the trigger bar out. Put a finger on the trigger bar from inside. With your other hand, nudge the spring out, push it down and release the spring slowly. Remove the trigger bar spring. Next remove the trigger bar. You can use a screw driver to slowly pry it out. In the trigger well, the spring will snap; the spring will remain in the frame, however.
Over the trigger well, remove the headed trigger pin. Take the trigger out through the top of the frame.
Voila! Your Beretta 92FS 9mm hand gun has been successfully disassembled. Its parts are now ready to be cleaned using an ultrasonic cleaner.
Step 2: Cleaning the Beretta 92FS Firearm
Use the weapons kit brushes and tools to remove powder residues, bullet shavings, carbon and other loose contaminants. Tip: If the weapon is extremely dirty it should be cleaned using hot water to prepare the cleaning bath.
Put the hammer in the cocked position. Lift the star shell ejector and place a spacer between the star and cylinder to enhance cleaning action. Position your weapon parts in the mesh basket in a way to avoid air entrapment. Lower the basket into the cleaning solution and set the timer for 7-10 minutes. Cleaning time depends on the condition of the weapon.
At the end of the cycle remove the handgun components from the bath. If they are not clean replace them in the bath until the cleaning is complete. Do not reach into an operating ultrasonic bath. Remove the basket from the bath if you want to inspect or rearrange the parts.
After cleaning rinse the parts in fresh water to remove all traces of the cleaning solution, shake them to remove excess water and allow them to drain. Compressed air will aid in this process.
Return the weapon parts to the basket.
Next place the lubricating pan into the ultrasonic cleaner again making certain that the bottom of the lubricating pan is in contact with the ultrasonic cleaning solution. Put the basket into the lubricating solution and set the timer for 10 minutes. Ultrasonic waves will pass from the ultrasonic cleaning bath to the lubricating bath and thoroughly lubricate the weapon parts.
After the lubricating step remove the parts and allow them to drain. Do not blow dry. Inspect then oil the parts according to the manufacturer’s instructions before reassembly.
Step 3: Reassembling the Beretta 92FS Handgun
After using the ultrasonic cleaner, you can now reassemble all the parts of your Beretta 92FS 9mm. Replace the trigger in its proper position through the top of the frame. Align the trigger by putting the headed pin through the hole of the frame and into the first loop of the trigger. This will help keep the trigger in place as you guide the pin and the spring back. Prevent the trigger from moving around by pressing it in fully as you keep a finger on the pin’s head. Carefully insert the spring into the detent of the trigger from above. As you press the spring in, push the headed pin to insert it through the spring.
Now pop the trigger bar partially in place. You may use other tools handy for the next step. Keep the trigger pressed and slowly push the trigger bar in just enough. From above the frame, nudge the spring arm of the trigger so it grabs unto the trigger bar from inside. Ease the trigger back into its initial position and push the trigger bar in place. Remember not to push this all the way in, as its edge will catch unto the frame. Next insert the spring back into the frame.
Gun care tip! Be careful not to scratch the frame with any of the edges or catches sticking out of the parts as you push or wriggle them back into place.
To install the slide stop, insert the spring unto the catch with the straight end resting on the protrusion and the arm sticking out of the slide stop part. Hold the straight edge in place as you insert the hooked arm into its small slot of the frame. Carefully push the slide stop all the way in back into the frame.
Drop in the hammer strut (straight end first) into the handle area. Note that the bent end is positioned in such a way that it angles towards the rear of the Beretta 92FS. Put the hammer back in on top and push the sear with it. With the hole of the hammer and the frame lined up, push the headed hammer pin to the left side.
Pressing unto the hammer lever, keep the hammer in an upright position. Shake the frame slightly to make sure the hammer strut falls into the hammer. As you hold the hammer lever, upend the frame to be able to slip the spring into the handle and around the hammer strut. Carefully press the main spring housing (the opposite end of the lanyard loop) over the spring and hammer strut. You can return the frame in a normal position, keeping the lanyard loop in place by pressing it against a hard surface. With enough pressure, press the frame down to slip the headless pin back into the small hole on the left side near the handle end. This will lock the lanyard loop and the main spring.
For the disassembly button, slip the spring into place, followed by the disassembly button itself. As you press unto the button, slip the latch lever back on the other side with the handle facing upwards. Rotate the latch lever handle down while still pressing on the button. Once it is facing down, release the button.
For the magazine catch assembly, put the spring between both sliders. With one end of the sliders in place on its small frame, compress the other end and fit this into the space. From inside the frame, insert the magazine catch into its groves. Slip one side first and as you hold the sliders against the frame from inside, you can easily snap the other side into its grove.
Safety tip! Make sure the frame does not contain its magazine when you reassemble the main components. On the reassembled Beretta 92FS frame, check the disassembly latch. The latch handle should be pointing downwards. Be careful when handling the recoil spring and the spring guide. You can now piece together the slide, barrel, frame, and recoil spring of your Beretta 92FS. Screw the grips back.
Congratulations! You have just reassembled your “brand new” Beretta 92FS Handgun.
Additional Weapon Cleaning Tips
Oils that rise to the surface of the bath should be skimmed off and disposed of properly. When the ultrasonic handgun cleaner solution becomes discolored or cleaning takes longer it is time to replace it. Drain the tank and dispose of the spent solution according to local regulations. Take the time to remove sludge that settled to the bottom of the tank then clean the tank.
