I've had my fill of the 10...maybe. I've owned and shot a bunch, successfully reloaded it, etc. Right now it doesn't interest me a lot. The 40 never did, but at one time everything was off the shelves around here but 40. So having resisted the cartridge for years, I got one. I've got a 40 right now because I've got a lot of 40 ammo. I never did stock up on the 10 properly, or I'd still have one of those.
