What you see is a small reflex of led light bulb on the lens. One simple and quick way to find out is to use your cellphone to take a photo of the dot.If you see a circle dot in the photo you took, you basically diagnosed you have Astigmatism(Because cellphone is a machine does not has human astigmatism) BulletPoint6 : This listing only comes with a picatinny plate.If user has a Springfield OSP(optics ready) model that has a optic cut in front of the rear sight, user need to obtain Springfield provided #01 plate.The springfield official Sku is XD5071, you can obtain that plate from springfield for free. If user has a Non-OSP(non-optics ready) XD, XD MOD.2, XD(M), XDS Pistol, user need to purchase an aftermarket optic plate to replace the rear sight, please search amazon Item Number B087H5GHCR for the plate.
