I already have a pcp target pistol, had a FWB 65, but due to a bad right elbow, I couldn't manage the side lever cocking. I recently purchased a 6G that has been my first experience with the Giss system, and I am quite impressed, but the limited trigger adjustment is a bit frustrating.
The Model 10 looks a sleeker bit of kit with a lower sight line and better anatomical grip.
I don't think I would ever use one for serious competition, but it would fill the void left by the 65 as a 'vintage' target springer.

And IMHO, the 10 just looks so cool!
