Disclaimer: Modifying your firearm without proper knowledge and precautions can result in fatal injuries! If you follow this guide, you do so at your own risk.
Always work with unloaded firearms and with no live ammo on the workbench.
Assume ALL firearms are loaded!
Step 1:
Remove the slide from the frame and flip the safety to the On position.
Lay the slide upside down on a set of bench blocks to avoid marring the finish. A roll of tape also works as a substitute for blocks.
Step 2:
Using a small punch, knock out the two tiny roll pins securing the right side of the safety lever.
Step 3:
This step is a little tricky and requires some dexterity.
You will have to depress the firing pin safety plunger (firing pin catch) while pressing the firing pin plunger down while simultaneously flipping the safety to the 10 o'clock position.
Here's how I do it. Grab the slide in your left hand with your thumb pressing up on the plunger. While holding a punch in your right hand, press down on the firing pin. Keeping pressure on the firing pin, you can release the safety plunger and flip the safety to 10 o'clock.
Step 4:
Use caution on this step as there are two spring loaded detents that will be released when the safety is removed from the slide.
Cover the slide with a cloth or work in a clear plastic bag or zip-loc. You want to ensure that the safety device is covered on both sides of the slide.
Press the safety plunger while pushing the safety from the right side. You should hear a couple clicks as the detents pop free. You can remove the cloth or bag at this time but be careful not to lose the detents and springs.
You should be left with two detents, two springs, a firing pin plunger, your old safety and the new replacement.
Step 5:
Insert the firing pin plunger into the replacement safety like in the image below ie. cap end towards the lever end.
Press down on the firing pin safety plunger on the slide and insert the safety from the 7 o'clock position, pushing it inwards while rotating it to the 10 o'clock position. Do not insert the safety all the way in.
Step 6:
Insert the left and right detents and springs. The small one goes into the hole on the slide, the large one goes into the safety.
Using a punch, press down on the small detent and push the safety inwards a bit to capture it. The large detent on the safety will prevent you from pushing it in all the way.
You can place a piece of tape on the lever side of the slide, just in front of the safety to prevent possible marring of your finish by the large detent.
Using a punch, push the large detent into the safety while pushing the safety inwards. The whole assembly should click into place on the slide.
Step 7: Safety & Function Check
Flip the safety on and then off position. It should not go back into the 10 o'clock position.
Reassemble the slide to the frame and return the slide to the closed position, the hammer should remain cocked.
With the firearm unloaded, flip the safety to the on position. The hammer should drop and the trigger should move through the full range yet remain inoperable ie hammer does not become engaged. The firing pin safety plunger should lift when the trigger is pulled to the back.
Flip the safety off and pull the trigger half-way back slowly. The hammer should half-####. Release the trigger and the hammer should remain in half-#### position. Flip the safety to the on position. The hammer should drop.
With the safety off, rack the slide and then pull the trigger. The hammer should drop.
With safety off, pull the trigger all the way back. Hammer should #### all the way back and release ie. double action.
Continue to hold the trigger all the way back and rack the slide. Release the trigger, the sear should engage with a click and the hammer should stay cocked.
Engage the safety, the hammer should drop.
Rack the slide with safety on. Hammer should follow the slide back to the down position.
Step 8:
Hit the range.
