I just did a dis-assembly/re-assembly of the slide on a brand new PM40.
If my gun is not faulty, this has to be the worst slide stop arrangement I have ever seen. Driving the stop out is far harder than I would think is reasonable. Once I get the index marks lined up, there is no way to just push out the stop. You have to drive it out. Can't do it with just 2 hands.
Putting it back in is almost as bad. The little spring that has to be engaged by the stop has to be lifted into place with a tiny screwdriver.
This doesn't seem right to me.
I have several different types of semi-autos, and I have never had one that was anywhere this difficult.
Any one else had any experience with this, or does this sound like a factory problem?
