you will love the xs sights....i put it on mine..it's the best sight .....
also if you take a tac-star 6 shot side saddle, and cut the holder back to 4 rounds..the extra that sticks forward can be modified to install the rail that came for the top on the side....for light..whatever. won't interfere with slide action (hand passes by light with out any interference). also put a cheap little laser on it...opened it up filled it with non-conductive silicone...now it holds zero and is ressistant to recoil
great little gun...have had no problems at all
