While the bullet design of all SFX cartridges facilitates smooth and reliable feeding in semi-automatic handguns, the bullet give and propellant impulse of the 9 mm SFX have been specifically engineered to provide trouble-free, reliable feeding. This enables the use of high-performance hollow-point cartridges to be as dependable as FMJ ammunition. SFX meets existing law enforcement protocols. Mfg: Pmc Ammunition
