My feelings are guns are tools some have an extremely high price but are tools none the less. Now if you want your tools to last and work properly you do have to look after them to a reasonable standard that includes repairing them if something should go wrong. So taking this to its final conclusion the more you use a tool the more service and repair it will need until repairing surpasses the point that it is not economical to do so and its useful life has come to an end. Now the only way in reality is to purchase your extremely expensive tool and not use it and in that way it will stay in the same condition as it left the manufacturer but where is the true reward in that I ask?
Maybe one day you will be able to purchase guns preserved in aspic if that is what people want but not me!!!!
Buy them use them service them and in doing so enjoy them!!!
