The Victory has the best trigger of all the Sharp airguns imo. But it is much heavier to pump than the Innova and Ace. The Ace is the easiest/lightest to pump. It has a longer pump arm. The Victory is relatively short. I am always afraid to cause damage when I put the 8th pump in.
Plastic on the Innova - it makes it so nice and light! It's super good plastic, I haven't had any issues and these Innova's are almost 40 years old.
But I understand that some people just don't like plastic on a gun period.
