I don't pretend that my 'collection' has any special value or significance for a true collector. It's more than just a random accumulation though.
Most of my guns fill a niche for me or they're just guns that I've always wanted. I've had my share of Stars, Rugers, Glocks, later model Smiths and I still have some of them.
As time, money and opportunity have allowed, I've sold and traded most to replace them with Sigs, Colts, and earlier Smiths. I can see myself continuing to refine my 'collection' and add to it with the gems that I find along the way.
To a much greater extent than most mechanical devices, firearms are terribly unforgiving of any overconfidence, complacency or negligence.
