You're right. I don't handle a straight Compact much. Mine is modified to use the CZ 85 ambidextrous safety and slide release so I'm used to looking at that. I just checked my wife's Compact and the darn thing does stick out way farther (maybe) than necessary. Then again, it may be that it sticks out enough to make it easy to push it far enough to get it to release from the spring that holds it in place inside the frame.
Shortening it will be a small "custom" touch to your pistol but may make it a little more difficult to field strip.
Considering the reports that CZ's will occasionally break the slide stop, do you think you should buy a spare and have it hard chromed, too? And just put it away as a ready to go spare so it would match the rest of the frame/parts?
