I currently have an 18" barrel on my Talon Pistol, and it zips 33 grain pellets (@900fps) very nicely out to 75 yards. I have the idea of fitting a 24" barrel onto the frame so I can go out past that distance with these pellets. The air gun already has a 500cc tank on it, so I'm not worried about shot count. I'm just wondering if the short frame can support the extra barrel length.
