Welcome to the Forum. Several different guns have the Bodyguard name. If your user name is the gun in question, you have an alloy J frame in matte blue with a steel cylinder. An earlier version of this one was the model 38, or the 49 with a steel frame. Put the number 6 instead of 4 in front of your gun and it is silver alloy with a stainless cylinder. Lastly, there is the latest version with a polymer lower frame, with the laser. Not to mention the Bodyguard .380 auto...
Simple, right?
Hope this is helpful.
