This is my was my Duty Pistol which was given to me when I retired. Ironically the last 3 digits of the serial number are 822, which is the date I retired. It started life as a Gen 3 Glock 22. ( That's Right a Get you Killed In The Streets .40). We've rode together for more than a few miles. As you can see, I've done a few modifications. Slide Cut for a Trijicon RMR, Ameriglo Suppressor Sights, Vickers Slide and Magazine Releases, Vickers Flat Trigger, Gadget SCD, I undercut the Trigger Guard, Removed the Finger Grooves and Flattened the Backstrap and did the Stippling. A Streamlight TLR 1 HL Rounds out the package. I also have a 9mm Lonewolf Conversion Barrel and complete 9mm internals and magazines when I shoot 9mm. Yes I know the whole 9mm is King .40 is Dead thing. I can shoot either caliber at my Rate of Assessment and either caliber will get the job done, and with a full conversion 9mm is just as reliable as .40 is in this pistol and vice versa.
