Like most of you, I like DIY. I decided to upgrade my 20 year old Dwight Shuh Fieldline pack (god forbid I buy a new pack) and came upon AustriAlpin. Game changer. I ordered a discounted 2" Cobra buckle and slapped it on my hipbelt. These buckles are used in the millitary and simply will not open accidentally, yet open easily with one hand. Can't recommend AustriAlpin enough, even if you got a new pack, look at these buckles.
