First depress the firing pin so that it clears the manual safety assembly. I use a small punch to do this. With the firing pin depressed, push out the safety, right to left. Be aware of the plunger and spring that will launch once the safety handle clears the slide... After the safety clears the firing pin, just pull it out. Might need to rotate the safety a bit to find the path of least resistance for complete removal. Once the safety clears the firing pin be aware that the firing pin and spring will want to launch too...
