FIELD STRIPPING
SW99NJ
During field stripping of your pistol:
WARNING: ALWAYS POINT THE MUZZLE IN A
SAFE DIRECTION AND BE SURE TO KEEP YOUR
FINGER OUTSIDE THE TRIGGER GUARD. BE SURE YOUR
PISTOL IS UNLOADED BEFORE DISASSEMBLY.
•To disassemble, depress the magazine release and remove 
the magazine. Grasp the rear of the slide and briskly pull it
fully rearward to eject the cartridge from the chamber.
WARNING: Do not obstruct the ejection port
because doing so can interfere with ejection of a
cartridge and thereby creates the risk of exploding
an unchambered cartridge and possible injury.
•Lock the slide to the rear by pushing the slide stop lever 
upwards while pulling the slide back and allowing it to go 
forward slightly to be held rearward by the slide stop lever.
•Look into the chamber and down through the magazine well.
Verify that no ammunition remains in the pistol.
•Pull the slide to the rear and release it or depress the slide 
stop lever to allow the slide to move forward.
WARNING: To complete disassembly, you will be
required to pull the trigger. If you have failed to
unload your pistol and a round is left in the 
chamber, the pistol will discharge and may cause injury.
Therefore, be sure that the chamber is empty before
proceeding further.
•Verify that the muzzle is pointed in a safe direction and pull 
the trigger to decock the striker for disassembly.
•Pull the slide back about 1/8” and depress the takedown 
catch on both sides of the frame with your thumb and 
forefinger. (Figure 11)
•Push the slide off the frame. (Figure 12)
•Grasp the slide just behind the front sight and remove the 
slide by pulling it forward while being careful to retain the 
recoil spring and guide rod assembly. (Figure 13)
•Remove the recoil spring, guide rod assembly and barrel.
(Figure 14 & 15)
•The pistol is now ready for normal cleaning and lubrication.
Further disassembly is not recommended and should only be 
undertaken by a Smith & Wesson Certified Armorer or the 
Factory Service Center.

•With the rear of the slide pointed in a safe direction and the 
bottom of the slide turned up, replace the barrel in the slide

							CLEANING AND
MAINTENANCE
!!  WARNING  !!
Ensure your firearm is unloaded before beginning to clean
it. At all times follow the basic rules of safe gun handling.
Your firearm is a precision instrument and to insure reliable 
function, it is necessary to follow a routine maintenance 
procedure. After firing your firearm, be sure to unload it following
the procedure outlined in the section entitled “Unloading” on
page 20 before any cleaning or maintenance procedure. Your
pistol should be cleaned by brushing the barrel bore and 
chamber with a good powder-removing solvent and bore brush.
Wipe the areas clean with patches or a swab. Using a small
brush dipped in solvent, remove all deposits from around the
breech of the barrel, and chamber, extractor and adjacent areas
which have been subjected to the action of powder or primer
residue. Remove any residue on the frame with light brushing
and a solvent. After cleaning the entire gun, use a cloth to apply
a light film of high quality gun oil to all external metal surfaces
and wipe clean.
Cleaning is considered essential in order to ensure the proper
functioning of your handgun.
For additional maintenance, we recommend the services of a
qualified gunsmith. Please refer to section entitled “Service”. If
your firearm will be used or stored in a cold climate, be sure to
use an oil that will not thicken at low temperatures.
ASSEMBLY (see Figure 16)
1. Install magazine follower (2) in bottom of the magazine tube 
(1) with the notched edges of the magazine follower (2) 
toward the round side of the magazine tube (1).
2. Install magazine spring (3) and floorplate catch (4) in 
magazine tube (1).
3. While holding floorplate catch (4) in magazine tube (1), slide 
magazine floorplate (5) into magazine tube (1) so that the 
round projection of the floorplate catch (4) engages the 
magazine floorplate (5).

such notification and delivery of the handgun as provided below.
If any unsafe and/or illegal condition is found during warranty
