Default Complete Disassembly & Assembly of ALL S&W Model 52s

Disassembly and Assembly Of The Smith & Wesson Model 52 - These Instructions Cover all versions of the Model 52


Necessary Tools:

Have available the following tools to work with:

- Schematic and Parts List for both the early and later Model 52s (see below)
- Small table vice (optional)
- Small Magnetic Tray to hold small parts (optional)
- Polymer Armorerís Block (optional)
- Handgun Rear Sight Tool Remover
- 1/16th, 3/32nd and 1/8th steel punch. Brass punches are useless as they will bend out of shape.
- Small Brass Hammer having both a Brass and Polymer head
- Flat Blade Tool Driver Set
- Torx T5 and T8 Screw Drivers
- Dental Pic for removing small springs
- Tweezers for removing and putting small springs and plungers back in place
- Small Wooden Dowel to assist in moving the Rear Sight if needed

Field Strip

Field strip your 52 by drawing the Slide back to the point where the rear of the Slide Stop lines up with the notch in the left side of the Slide. From the right side of the Slide push the small protruding nib of the Slide Stop towards the left side of the Slide then extract it from the Slide all together. You can now remove the Slide containing the Barrel and Recoil Spring Guide Assembly by withdrawing it forward from the Frame.

While holding the Slide in one hand after itís removal from the Frame, push the Barrel out of the Slide a few centimetres with your other hand. While holding the Slide with the slightly extend Barrel, push down on the small spring loaded Barrel Bushing Plunger. While holding the Slide with the slightly extended Barrel and pushing down on the Barrel Bushing Plunger with one hand, rotate the Barrel Bushing with your free hand and completely remove it from the Slide along with the Barrel Bushing Plate. You can now remove the Barrel from the Slide by pushing it back into the Slide then remove it.

Slide Disassembly:

While holding the Slide in one hand take your 1/16th steel punch and from the rear of the Slide push the spring loaded Firing Pin all the way in and hold it there. Be careful that the spring loaded Firing Pin doesnít slip off your steel punch as it will come flying out of the slide. While holding the Firing Pin in with your punch, rotate the Manual Safety slightly back and forth while slowly pushing or pulling it out of the Slide. While doing this, be mindful of the very small Manual Safety Plunger and spring located in the well wall of the Manual Safety as you remove it. On the early Model 52, the Manual Safety Plunger and Spring are located in the rear of the older flexible style of Extractor. You DO NOT want to lose the Manual Safety Plunger and Spring.

Now that the Manual Safety has been removed, the next item to remove is the Ejector-Depressor Plunger and Spring. In order to do this, the Rear Sight must be moved. First remove the Rear Sight Lock Screw using your Torx T5 screw driver/wrench. With your Rear Sight Remover Tool or Small Wooden Dowel and Brass Hammer, move the Rear Sight to the right while being careful of the Ejector-Depressor Plunger and Spring which are installed beneath the Rear Sight Base. Once the Rear Sight has been moved over, you can extract the Ejector-Depressor Spring first then the Plunger from the Slide. Finally with your 1/16th steel punch, drive out the Extractor Pin from the top of the Slide and then remove the Extractor and Extractor Spring. The early Model 52s use a flexible style of Extractor. In order to remove this version of the Extractor, you will definitely need to use a small table vice in order to firmly lock the Slide in place. In order to proceed, the centre point of the Extractor must be compressed while at the same time raising the Extractor tip at the breech and simultaneously pushing the Extractor rearward. Personally, I wouldnít attempt this removal as the early style Extractor has a tendency to break very easily. This particular step is a job for a professional gunsmith with the proper tools. This completes the disassembly of the Slide.

Reassemble The Slide:

To Reassemble the Slide simply follow the Disassembly instruction in reverse order. Remember to be very careful when installing the small springs and plungers.

Frame Disassembly:

First remove the grips from the Frame. After placing the hammer in the fired position you then, with the 1/8th steel punch, drive out the Insert Pin which allows for the removal of the Frame Insert, Mainspring Plunger and Mainspring. Next remove the Side Plate Assembly by simply pulling it out of the Frame. Now remove the Hammer with Stirrup. From the top left rear of the Frame, remove the Ejector and Magazine Depressor along with the Ejector Spring. With your 3/32 steel punch drive out the Sear Pin from the right side of the Frame and remove the Sear. Be sure to note the orientation of the Sear when removing it. Also be mindful that the early model of the Sear is different in appearance then the later version but still installed the same way. You will also note that earlier model 52s do not have a Sear Spring. With a small flat blade screw driver, push down on the Magazine Catch Plunger and then unscrew the Magazine Catch Nut in order to remove the Magazine Catch itself. Now comes the tricky part. Looking down from the top of the Frame into the Trigger well we can see the Trigger Stop Screw - Upper. While looking down and pulling back on the Trigger, youíll notice that the back section of the Trigger Mechanism catches on the top front of the Trigger Stop Screw - Upper. With your Torx T8 wrench screw down on the Trigger Stop Screw - Upper as this will allow the back of the Trigger Mechanism to clear the Trigger Stop Screw - Upper. The Disconnector can now be removed (note itís orientation first) by pushing forward on the Drawbar from the rear Frame opening which will allow it to fall out from itís position above the Sear. On the earlier model 52s, which have the older version of the Drawbar, it must be moved towards the rear of the Frame. You will then be able to poke out the Disconnector from the top of the Frame with a small screw driver or punch. Using your 1/8th steel punch, drive out the Trigger Pin. Once removed pull down and move the Trigger blade forward in the Trigger Guard. While keeping the Trigger in that position use your thumb and index finger of your free hand to grasp through the side openings of the Frame the Drawbar and move it to the rear and eventually extracting it completely from the Frame. You are now able to remove the Drawbar Plunger and Spring, which are located just above the Trigger opening, by simply tilting the Frame which allows the Drawbar Plunger and Spring to fall out, otherwise use your tweezers to remove them. Please be aware that the early version of the Drawbar incorporates a part called the Trigger Play Spring which plays a role in allowing DA capabilities. DO NOT remove the Trigger Play Spring from the Drawbar, unless itís absolutely necessary as itís fragile and could be become damaged. With your Torx T8 wrench, completely unscrew and remove the Trigger Stop Screw - Upper. Finally grasp the Trigger then push it up and out of the frame in a forward rolling motion. The Model 52 Frame is now completely stripped of all parts except the Trigger Stop Screw - Lower (not necessary to remove) and the Sear Spring on later model which should NEVER be removed unless itís absolutely necessary. Itís very important to note that the Trigger Stop Screw - Lower, the Trigger Stop Screw - Upper along with the Trigger Play Spring are the components responsible for helping to implement DA on the early Model 52s. By moving the Trigger Stop Screw - Lower outwards inside the Trigger Guard to the point that the pistol will fire just as the Trigger touches the Trigger Stop Screw - Lower, along with tightening all the way down the Trigger Stop Screw - Upper, places the Model 52 in DA mode. Keep in mind that it can be somewhat difficult to return the early Model 52 back to SA mode because of the precise position that the Trigger Stop Screw - Upper must be in.

Reassemble the Frame:

To Reassemble the Frame simply follow the Disassembly instruction in reverse order. Remember to be very careful when reinstalling the Disconnector by insuring that the Drawbar is all the way forward when inserted. Once installed bring the Drawbar back to itís normal position trapping the Disconnector in itís place. When reinstalling the Drawbar be certain that the upper claws on the Trigger properly engage the Drawbar so that it easily moves back and forth prior to reinstalling the Trigger Pin. Also remember to adjust the Trigger Stop Screw - Upper which will keep the Trigger and Disconnector in their proper positions.
