S2 and TS safeties will not work on the 75b/SP-01, S2/TS and 75 compacts have a wider frame. You can fit a wide S2 style safety to the gun though. The 2019 SP-01 shadow orange came from the factory with a S2 style wide safety. The only place I was able to get them from was luckydelta.com and pay international shipping. It was worth it though and I have bought 4. It changes nothing and usually require little to no fitting but I’m sure you can find details in the gun smithing pages of the forum.
