There are many factors in pistol shooting that play a far bigger role in accuracy than consistent case length. Start with the gun being held at arms length by 2 hands instead of having 3 or 4 points of contact with your body.
Then, consider the ehort barrel. Its not going to be as accurate as a 16 to 24 inch barrel.
Then consider the short sight radius (distance between rear and front sight). Way less accurate than a rifle.
If you feel better by doing it, please, by all means, trim it. But its not a big factor. If you use that time practicing your draw and dry firing with snap caps, it will prolly help you a lot more.
