Just picked up a PSA multi cal lower with a 9mm mag block installed at a local gun show. It Takes tthe colt pattern mags. Will this lower work with the PSA hybrid uppers? Do I need to change the hammer? Anything else I should be aware of? Thanks

The hybrid uppers work with both types of lowers. You are good to go.

You may need to change the trigger and hammer. Some Two stages (like the ssa and LaRue) have been reported to double on some PSA 9mms.
