Refurbish Your Smith & Wesson Model 19 with an Ultrasonic Cleaner

Smith & Wesson’s Model 19 revolver is a firearm classic. Being continuously manufactured for over 40 years, the Model 19 revolver has proven its excellent performance and handling qualities for various uses. It has a 6-round cylinder and an adjustable sights system which makes this revolver an ideal choice for both indoor and outdoor shooting activities. Your revolver needs to be kept clean inside and out to preserve its polished look and sound performance. To achieve this, an ultrasonic cleaner can help you meticulously rid your revolver of dirt and dust.

If you own or service Smith and Wesson Model 19 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.

Here you will learn:

  • How an Ultrasonic Gun Cleaner Works
  • How to Select and Set Up your Ultrasonic Weapon Cleaner
  • How to Disassemble, Clean and Reassemble your Smith & Wesson Model 19

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 Smith & Wesson Model 19. 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 Smith & Wesson Model 19. 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.

  1. 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.
  2. 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.
  3. 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 Smith & Wesson Model 19 revolver

Step 1: Disassembling the Smith & Wesson Model 19 firearm

Safety tip! Before taking apart your firearm, make certain that it is not loaded. Face the revolver in a safe direction throughout the process. Make sure that Smith & Wesson revolver is pointed towards an open area or a wall to avoid accidents and injuries. Also gather necessary tools such as screwdrivers and a rubberized hammer beforehand.

Begin by removing the grips. You will need an appropriately sized screwdriver to release the screws that fasten the grips in place. Remove the crane by working loose the screw found below it. The crane should easily come right off once the screw is detached from your Model 19 revolver. After this, hit the release button or latch found on the left side of your firearm and take the cylinder out completely. Expect minimal difficulty in removing the cylinder and the crane once you remove the latch. Lift the crane from the cylinder to push the ejector out to separate the crane assembly.

Going back to your Smith & Wesson’s main structure, loosen another screw on the frame’s rear end. The screw is placed right above the grip’s original position. Work loose another screw found on the same area of your Model 19 revolver.

Safety tip! Be mindful of the screws that you remove from your firearm. Most of these screws are small and in different types. Arranging them in a way that would help you remember their original positions is advised. Returning the screws in their original places will ensure your safety and the good performance of your firearm.

You will need a rubberised hammer to completely remove the right cover plate of your Smith & Wesson Model 19. With the left cover plate facing up, place the gun on your palm. Lightly tap this side with a hammer until the underside falls off. Note that a hammering bar comes off with the right cover plate. Next, remove the main spring found in the grip area. You will need to loosen up a screw on the lower right side of the grip skeleton. Take the screw and carefully lift the main spring from its place.

Now you can remove the hammer of your firearm. Release a small silver plate that rests behind the crane case and pull it backwards. Insert a screwdriver underneath the hammer to aid in lifting and removing. After this, move the hammer from side to side to loosen it up. Then take the sliding block out by pushing it upwards carefully using a screwdriver. Note that utmost care should be given since the sliding block has spring tension. Lastly, move the trigger from side to side until you are able to unfasten it.

Voila! Your Smith & Wesson Model 19 handgun has been successfully disassembled. Its parts are now ready to be cleaned using an ultrasonic cleaner.

Step 2: Cleaning the Smith & Wesson Model 19 revolver

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 Smith & Wesson Model 19

Begin by putting the cylinder assembly of your Smith & Wesson revolver back together. First, reinstall the crane and the ejector on the main frame. Set this assembly aside and work on the trigger assembly. Connect the silver plate to the trigger by lifting the spring inside of the trigger to free up space for the linking. Join them tightly before returning the trigger back in place. Make sure that it is pushed well on the body of your firearm to ensure safety in every pull of the trigger. Then return the slide block on the left side of the trigger assembly. Note that the direction of the screw inside does not really matter. You may use a screw driver to help you set the slide block in without bending the screw.

Next, return the hammer in its proper position inside your Model 19 revolver by pulling on the trigger. After this, carefully fit the hammer in its position and push it down until it is fixed in place. Now look for a small hole at the bottom part of the hammer. This serves as the link between the hammer and the main spring. Hook the main spring on top and slide in the bottom lining of the grip. Secure this assembly in place with a screw. Make sure that the tension is appropriate. Then place the hammer bar over the hammer assembly to link it to the peg found on top of the silver plate.

Seal the internal components of your firearm with the right metal cover. Note that the right cover has a mould for the hammer bar. Fit the hammer bar correctly to be able to close the cover. Hold the cover in place by tightening two of the screws found on this surface.

Place the crane assembly and cylinder in their proper position. Secure this assembly before locking it in place with the crane screw located under the said assembly. You may now put the grips back on your Smith & Wesson Model 19 using the screws that hold them in place.

Congratulations! You have just reassembled your “brand new” Smith & Wesson Model 19 revolver.

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.
