I got this P 08 loading tool at Midway awhile back for a few dollars based on a recommendation I read on this forum. The hook on the bottom snaps onto the base of the magazine when fully depressed, keeping the follower down which is very helpful in cleaning the magazine. It fits the magazines perfectly and has a comfortable serreted landing for the thumb to push the follower down. I have stronger springs in my aftermarket P 08 magazines, installed by GT, and without this tool my thumb would probably be gone by now.
It's $3.99 at Midway currently backordered.
