i went and handled the Neo this weekend and i will say it fits REALLY nice in your hand. Also handled the walther 22lr and dispite the small look its fits very very nice in your palm as well. if it wasnt for the $300+ price tag on a 22lr pistol i would go with it. But the Neo is gonna be my next purchase in the 4.5" i think, the 6" is just to front heavy, should be accurate tho.
