I'm planning on putting a G32 barrel in my G23C RTF2 for carry purposes. While looking for night sights I noticed the TFO's have a separate model for the 23 and 32. Are the sights different heights? If anyone has experience shooting a 23 with a 32 barrel and stock sights have they noticed a point of aim/point of impact difference? Is the .357 sig shooting high or low out of the 23? Any input you could provide would be helpful. Thanks.
