Hi Michael and welcome. Unfortunately, no, the Fusion XP Pro utilizes a proprietary magazine release that is not designed to be swapped for left-handed use. Cheers and stay safe!

Hi Michael, no, The magazine release on a 1911 is typically not reversible from the factory, and finding a left-hand mag release can be challenging.
Stay safe & have a great day!

Good afternoon to you!! Unfortunately no, the Fusion XP Pro's magazine release cannot be reversed. Sorry hope this was helpful. Have a good rest of your day.
