Smith & Wesson J Frame Spring Upgrade
Frugal

I'll be replacing the Rebound Spring and the Hammer Spring on my Smith & Wesson Model 63 (J Frame) with new springs from Wolff Gun Springs.

STEP 1: Unload firearm.

STEP 2: Remove Grips.
Use kinetic force if necessary, never pry.

STEP 3: Remove 3 screws holding the side plate on.
When working on ANY firearms project
always keep track of your screws so that you always put the same screw back into the same hole.

STEP 4: Remove cylinder and yoke.

STEP 5: Remove side plate using kinetic energy—never pry.
Rap sharply on the handle with a plastic handle screwdriver or plastic hammer until plate is dislodged.

STEP 6: Remove hammer block, cock hammer and capture hammer spring.
Hammer Spring can be captured with a small screwdriver, as shown, or something similar such as a paperclip.

STEP 7: Pull cylinder release, let down the hammer and remove hammer spring.

STEP 8: Release cylinder catch and remove hammer.

TOOL: I used a special tool, a Smith & Wesson Rebound Slide Spring Tool
from Brownells for $19.95 to remove the rebound spring.
You can also make one yourself with a Dremel tool and an old screwdriver.

STEP 9: Remove the Rebound Spring.
Using your Smith & Wesson Rebound Slide Spring Tool or modified screwdriver.

STEP 10: Replace with new Rebound Spring.
Using your Smith & Wesson Rebound Slide Spring Tool or modified screwdriver.

STEP 11: Pull cylinder release and trigger and replace hammer.

STEP 12: Uncapture hammer spring.

STEP 13: Recapture new hammer spring.

STEP 14: Replace hammer spring into grip and uncapture.

STEP 15: Replace cylinder and yoke.

STEP 16: Replace hammer block.

STEP 17: Replace side plate and screws.
When working on ANY firearms project
always keep track of your screws so that you always put the same screw back into the same hole.
