Have to say I was until today unaware of this -
It gives a sort of ''condition5''. I wonder how much effort is needed to tweak safety off and get hammer back but - in theory it seems to give best of all worlds and of course keeps gun mega safe for those who feel uneasy with con' 1.
The SAFETY FAST SHOOTING system combines the advantages of both mechanisms while eliminating their drawbacks. Available as a kit, it can be fitted into an existing pistol. The S.F.S. system is a drop-in kit.
The 1911 S.F.S. kit can be installed in a series 70 or series 80 style 1911. When installed in a series 80, the firing pin lockout system is still fully functional. The Browning Hi-Power S.F.S. kit can be installed in the new MK III Browning Hi-Power or the pre MK III Browning Hi-Power and the various clones. When installed in a MK III Browning Hi-Power, the S.F.S. kit retains the firing pin lockout system. The S.F.S. system does not eliminate the magazine disconnect on the Browning Hi-Power.
With the three safeties activated the S.F.S. allows the hammer to be cocked, and the safeties are then deactivated by simply pressing the ambidextrous safety lever with the thumb. The trigger pull remains light and accurate, allowing a very fast first shot.
