THE ALFA HOLEK REVOLVERS WITH THE CALIBERS .38 SPECIAL AND .32 S & W WITH THE LIGHT METAL FRAME ARE PRIMARY DESIGNED FOR COMFORTABLE WEARING DURING THE WHOLE DAY AND FOR SELF DEFENSE DUE TO THEIR LIGHT WEIGHT. THE LIGHT ALLOY FRAME CONTAINS STEEL CASTINGS AND INSERTS THAT ENSURE CONSTANT STEEL-ON-STEEL FRICTION TO ENSURE MAXIMUM SERVICE LIFE. THE LIGHT WEIGHT OF THE HOLEK REVOLVERS MEANS A MINOR LIMITATION ON PERSONAL COMFORT WHEN CARRYING. THEREFORE, THE HOLEK REVOLVER CAN BECOME AN EVERY-PRESENT, TRUSTED GUARDIAN OF YOUR SAFETY. THE MODELS 520 AND 540 CAL. 380 ALFA DERIVED FROM THE MODEL CAL. 38 SPECIAL ARE DESIGNED FOR NON-LETHAL RUBBER BULLET AMMUNITION. THEY ARE IDEAL FOR USE IN LESS DANGEROUS DEFENSE SITUATIONS WHERE THE ATTACKER IS EXPECTED TO BE LESS DETERMINED AND BRUTAL.
