Anyone know how to get the mag release assembly out of the IZH35M? I have some Walther KSP grips coming so I need to change the magazine release to a heel type release. There's a pin that seems to beholding the mag release in place but it doesn't want to come out. On the left side of grip the pin sticks out a bit, on the right side the pin is flush with the grip. Which side should I drift out the pin?
