 Not really sure, but it's a different experience, definitely. You've got to get a little bit used to it. You might love it. You might hate it. That's certainly true. But it is different and kind of goofy, but it works. If people don't know what we're talking about, you can look up the SIG P365SAS. No sights on top, rear sights kind of built into the back end of the slides. It's a weird way to describe it anyway.
