Does anyone have any chrono data showing velocity change for a 6-inch longslide compared to a 5-inch barrel? I was interested in data for 45ACP, 10mm and 9mm.
In 10mm, you will typically gain about 100fps AVERAGE, going from a 5" to a 6" barrel.... depending on bullet weight and other various factors. For example, a 135gr pill might gain 150fps or more while a 200-230gr bullet might only gain 40-50fps. That has been my experience. Either way, its substantial enough to consider, especially if using the 10mm for hunting.
