I bought the stainless praxis with the intention of it being my edc. It can't autofire or accidentally fire in my pocket, and it took the drop + rolled completely under my car, so it seems pretty bombproof.
After the second disassembly the negative insulator wore enough to no longer hold the negative spring captive. This isn't really that much of a problem, I just reassemble the mod upside down; switch stays in place in the body, negative insulator and spring get stacked on the negative end and I lower the mod onto the battery, insulator, and spring assembly.
My typical build is 26g stainless @ .22 ohms, I only use vtc4s. The only real problem the (clone) mod has is the surface of the brass negative contact pits really quickly. I know the authentics have a rhodium plated negative contact, which should in theory require less maintenance... Anyone that runs this sort of resistance have a mech with a rhodium plated negative care to chime in on how much of a difference it makes in your time between contact cleaning?
