The FN 5.7x28mm round is a specially designed cartridge for use in the FN fiveSeven pistol and P90 and civilian legal PS90 PDW rifles. The SS195LF is one of 2 civilian legal loadings for the popular pistol and rifle. Utilizing a lightweight 27gr brass jacketed aluminum hollow point, that is perfect for indoor use or where lead contamination is a concern. The 5.7x28mm cartridge was initially made at request from NATO to standardize a pistol and rifle cartridge to replace the 9mm with something that was as powerful out to intermediate distances of 200m or less while minimizing risk of collateral damage in the event of a miss or ricochet. The FN SS195LF 5.7x28mm cartridge pushes the 28gr projectile at just over 2000fps out of the rifle and pistol manufactured by Fabriquie Nationale which is great for small game or even personal defense.
