TaraSP, welcome to Sig Talk from the southwest corner of Indiana.
The SP 2022 has a Mil-Spec M1913 rail, instead of the propriety Sig specification rail. It is polymer, but I don't believe there is enough "flex" to interfere with a light.
I think the rail lock would be the best fit, since it is M1913 specification.
