Had some problems removing the tiny screws from the original open rear sight, but a little heat and the correct screw driver did the trick.
The only difference between the old and new front sight is that the new one is thinner.
What an improvement.
I even don't have to wear my glasses when using these sights.
It took me only 4 shots to get her on target again and groups are getting better with each shot.
I have a club match coming up in a couple of weeks where I will try out the "new" M39.
I will post the results after the match.
Some pictures.

New rear sight.
