How Do Ports & Comps Effect Muzzle Velocity & Rise? PMM, Ramjet, & Impulse Porting System

How Do Ports & Comps Effect Muzzle Velocity & Muzzle Rise? Today we dive into the question, does porting your barrel reduce the bullet velocity enough to prevent the reliable expansion of defensive ammunition? Also is there any notable difference in recoil reduction between the industry leaders in PMM, Ramjet, & the MapleLeaf Firearms Impulse Porting System?

Correction** I kept saying G45 but I meant G47 with a full length slide and radian ramjet setup. ** also the chart incorrectly states G45 and not G47 as it should…
