Durability, reliability and accuracy are important but...
Its hard to know where people are coming from and what they value in a handgun. Like a firearms durability. People talk about Benelli's and Glocks lasting 300,000+ rounds(shells in the shotguns case)...that doesn't mean anything to me. Its nice I guess but its like telling me that my No. 2 pencil could withstand a nuclear bomb exploding on top of it...."cool" I guess but it will never happen. This shotgun will last 300,000+ shells...Ok if I ever have that much money to spend on shotgun shells then the cost of buying several new shotguns wouldn't matter to me anyway.
I guess it depends on where you place value or what your looking for. Country of origin, aethestic appeal, cost of upgrades, ease of upgrades, historic value, resale value, saftey features, etc. etc. are some of the things that play a role in my purchases as well.
Glocks are by most accounts excellent pistols that are reliable, accurate and durable. On top of that they are cheap to buy compared to alot of other handguns.
