I recommend product if you don’t have suppressor high rear sights - Vortex OPMOD Viper 1x24mm Reflex Red Dot Sight

I’m a vortex fan through and through, waited 6 months to purchase this for my Springfield xdm osp. Now with that said, I recently purchased the vortex venom 3moa for the same pistol, in taking the pistol to the range I was able to adjust windage and elevation on the fly, this Vortex Viper will not allow me to do the same, because the windage and elevation adjustments have locking screws @ the rear of the sight. The Springfield XDM OSP comes from the factory with suppressor high iron sights which in return makes locking my adjustments into place final and then I have to remount the sight, not being able to correct any windage or elevation while back on the pistol..the mounting plate screws are about 1/8” too long as well and do not securely hold optic to the mounting plate and touch/dig the slide through the mounting plate
