Taking a closer look at the gun, I'm now 50-50 on modifying the frame (old std perfect circle style) to accept the S2 mag release vs. modifying the slidestop to fit it. The right side is already done, so it would just be the left side that needs modified, right? I could use the other side as a guide, and just drill/dremel/file it out to fit. Is there anything else to look for modifying the frame to do this? The frame is nothing special old 75B. Either way S2 mag release should be here next week.
Edit- Dang - the S2 mag release is out of stock in both places
