When you pistol only has 2.9 inches of barrel length, an addtional 1.2 inches IS A BIG DEAL.

What's that, 25 fps? 50?

Big deal is right.

Depending on the caliber and the load, powder type, etc, the difference of a 3” barrel vs a 4” barrel could potentially be as much as 100 lb-ft of muzzle energy. But that’s not all. Accuracy will also be enhanced.
