Glock 36 mag extensions?

Hello I was wondering if anyone had any experience with Glock 36 mag extensions, I saw that a few companies make them, I usually keep my stuff pretty stock (sights, optics, and a light being the only upgrades I’ll do on most). I’m looking to carry one or two extended back up mags, I saw pro mags makes an actual 10 round extended mag but I’ve had bad experiences with their mags in the past (with a S&W 380) so I figured just a base extension was the way to go. Any and all experience is welcome and I’d be grateful for any knowledge ya’ll can share!
