Curious if the length of the shaft is different also ? Use be a lot of complaints about the shaft sticking out the right hand side
Between these 2 styles for the P-01? Not sure. They seem to have the same shaft length. The one in the original post is about flush with the outside of the frame. I know the PCR side stop sticks out some.
Correction: The P-01 slide stop in the OP sticks out by about 1/16" from the side of the frame". Seems like the older style P-01 slide stop is about the same. (PCR sticks out about an 1/8" from the side of the frame)
Helpful tip... I use the bottom of a sharpie to pop the slide stops. They have a small dimple that fits perfect and doesn't slide off.
