A firearm, namely an automatic pistol such as a Model 1911, 1911 Al or the like structured to include a first portion of an elongate spring rod mounted in a space in a grip panel, and a second portion of the spring rod positioned within a notch in a thumb safety lever adjacent the grip panel. The spring rod is positioned to continuously bias the safety lever into the on-safe position wherein components of the pistol such as the hammer and trigger are locked to prevent discharge of the pistol. The safety is normally-on so that the pistol cannot be discharged absent the shooter intentionally and continuously depressing the safety lever into the off-safe position in order to discharge the pistol. The safety lever is continually biased by the spring into the safety-on position, thereby the shooter must continue to depress the thumb safety lever, overriding the spring, in order to discharge the pistol. Generally instantaneously upon the shooter releasing the safety lever, the spring returns the safety into the safe-on position wherein again the pistol cannot be discharged. In one preferred embodiment are two safety levers identically functional, one on each side of the pistol frame near the grip panels to allow the pistol to be considered ambidextrous to provide advantages to both left and right handed shooters in critical self-defense situations. Methods describing the ready converting of existing pre-manufactured pistols to include normally-on, momentary-off safeties are also disclosed.
