How to deep clean your gun -Smith & Wesson model 459

This is the 3rd generation model 459. Originally the FBI adopted the model 459 as their service pistol in the 80s but only issued the 1st and 2nd generation. the 3rd generation was made during the same time as the XM9 and the FBI opted to go for the XM9 instead. Due to this, there were only 803 of these ever made. I know my terminology is a bit off in some parts but bare with me, this is my first gun video. let me know if you got any questions
