Here you go; side profile of the TFO's along with a shot of it's newest accessory, the streamlight TLR-4 LED flashlight + Laser. I do have an Apex kit installed but only because I had bought 2 of them back when I first picked up my SD9. I checked with Midway USA and they say they are backordered until June 21st, but there are a number of places that sell them.
