First off I am not against a take down rifle as I own a couple. Search older rifles and they also bring a premium price. I see the need back in the day. A train or bus ride for a hunting trip. In this day and age you are not carrying a gun as carry on. And a model T did not have much storage space.Then there is special optic issues to mount on the barrel for best repeatable accuracy. For the same reason the sight radius is shorter for open sights. Althought I have good results with removable rifle mounts I prefer to only rely on this at the shooting bench. I have found I only break mine down for cleaning or testing or practice. I have been considering buying a take down storage pack for my PC 9. But then I think would I ever use the pack. I carry my fire arm when in the field for hunting or woods walking. I am not a fan of taking the rifle out of a pack assembly it going for a walk or hunt and then breaking it down to place back in the pack. A gun case seems more feasible to me. Again this not meant to put them down I just like to hear input on possible uses that I maybe missing out on. I have supplies coming to mount a red dot in place of the rear sight on the barrel of my ruger PC 9.
