I picked up a P10S that came with 10rd mags and noticed that the limiting factor for these mags is built into the spring not the mag body. I swapped a spring from a 12rd mag into the 10rd mag body and was able to get 12 rds. The mag bodies are the same dimensions as well.
Does anyone have a source or part number for the 12rd factory mag springs? I’m not really interested in cutting coils, stretching or modifying the spring on a carry gun.
Much appreciated!!
