Tossed my handheld in a backpack for a weekend trip and it came out without a scratch, which is exactly what I wanted. The bag hugs the 40XXV closely enough that there's no rattling around inside, and it still zips shut easily.
The fit is spot on for the RG 40XXV, no wiggle room at all, and the padding feels thick enough that I don't worry tossing it in my backpack. Took it on a week of commuting and the shell kept everything safe.
