I have had a good look at the gap round both parts of the barrel with a jewellers optic and there is no sign of dust or sand . The gap between the two barrels is so small that it's difficult to get a piece of paper into the gap. Whilst the gap between the outer barrel and the body is slightly larger there is no obstruction that I can see or feel except in two opposing place that might be the pins you refer to
No it's about 5 years old I think
