I learned to shoot on a Mk1 taper barrel that is as old as I am.
Shot straight and yes if you shot cheap ammo and didn't clean it regularly it would occasionally jam up but that was only after several hundred rounds.
I own 3 Ruger Mk style 22 pistols.
(1) Mk 3 - 22/45 - started out as a 6 inch fluted stainless - its now a 6 inch integrated suppressed
(2) Mk 2 - 22/45 - 4 inch blue bull
(3) MK 2 - with mk3 22/45 lower - 6 inch blue bull
I was given the 6 inch receiver so I located a bolt and grip frame.
All the MK3 lowers have had the mag disconnect removed.
The suppressed has one of the quick takedowns installed. You can remove the bolt without taking the grip frame off of it.
Just remove a allen head bolt and it slides right out.
