I have one of the DPD 2nd Gen. G22s that I originally bought as a collector's piece but like all my collector pieces I also like to shoot them. After putting 100 functionally flawless rounds thru it, I have discovered it isn't very accurate. Now I'm torn what to do about it. Part of me wants to keep it 'as issued' and part of me wants to 'upgrade' it and make it an accurate shooter. I already have several other GLOCKS in 9mm and 45 GAP and had never really wanted a .40 but when I had a chance to get a Detroit PD GLOCK, I went for it. So, should I refurb it or just leave it 'as issued' and just plink with it or should I refurb it for more accuracy?
