I know this is about the gen5 26 but was wondering if any of you guys have compared the gen4 26 against the gen5 26? I realize the barrel is really the only difference and I was curious if the marksman barrel is that much better in this little guy? I am ready to get one if I can find a blue label around me and it may be one of these I have the gen4 and not the gen 5 version in stock. Just thinking if I should hold out for the gen5 and order it or go ahead and just get the gen 4 gun if that is all I can find. I had a gen4 and sold it so thinking the newer gen5 is worth another try. Thanks and keep the info and longevity report coming GAP, I love hearing about guys guns they are testing over time...
