THE HOT BLUING SERVICE SHOULD BE PERFORMED EVERY 7-10 YEARS ON ALL 1931 MODEL FABRIQUE NATIONALE 6.35MM, PSP-25 AND PSA-25 HOT BLUED POCKET PISTOLS. DOING SO IS OF COURSE DEPENDENT ON THE CONDITION OF THE UNDERLYING 8620 STEEL ALLOY SURFACE AND THE BLUE FINISH OF THE PISTOL.

FOLKS OFTEN INSTRUCT US TO PERFORM THE HOT BLUING SERVICE WHEN THEY ACQUIRE A USED 1931 MODEL FN 6.35MM, PSP-25 OR PSA-25 POCKET PISTOL. AND THEY OFTEN DO SO AT THE SAME TIME THEY HAVE US UNDERTAKE THE SPRING REPLACEMENT SERVICE. NOW IS ALSO A GOOD TIME TO PURCHASE 1-3 MAGAZINES FROM US.

PROJECT SCOPE:

WHAT IS DESCRIBED BELOW PERTAINS SPECIFICALLY TO THE RESURFACING, HOT BLUING AND REBUILDING OF A "STANDARD" MODEL 1931 FN 6.35MM, PSP-25 OR PSA-25 6 SHOT HOT BLUED POCKET PISTOL. REACH OUT TO US IF YOUR HAVE A DIFFERENT MODEL. THE PROCESS AND PRICING MAY BE DIFFERENT.

THE PISTOL IS DIS-ASSEMBLED INTO ITS COMPONENT PARTS. PRIOR TO UNDERTAKING RESURFACING AND FINISH, THE PARTS ARE INSPECTED FOR CORRECT DIMENSIONAL TOLERANCES AND FUNCTIONALITY. WE WILL CONTACT YOU BY TELEPHONE TO DISCUSS ANY NON-CONFORMING PARTS OR OTHER ISSUES WE UNCOVER DURING THE DIS-ASSEMBLY PROCESS.

EACH PART IS THEN CLEANED IN A WATER-BASED DETERGENT WITH A PLASTIC BRISTLE BRUSH. THEN THE PARTS ARE CHEMICALLY STRIPPED OF OLD BLUING. IF SIGNIFICANT RUST AND/OR PITTING IS EVIDENT, THE AFFECTED AREA IS BEAD BLASTED WITH 1000 GRIT JAPANESE GLASS. THEN THE AFFECTED AREA IS RESURFACED TO OEM SPECIFICATION. WE STRIVE TO NEVER ALTER THE ORIGINAL OEM "LOOK" OF THE PISTOL. ALL PARTS ARE RESURFACED PRIOR TO HOT BLUING, EXCEPT PINS AND INTERNAL COMPONENTS WHICH TYPICALLY REMAIN UNALTERED.

THE PARTS ARE THEN ULTRASONIC CLEANED USING A HIGH TEMPERATURE CONCENTRATED GREASE REMOVING SOLUTION. THEN THEY ARE BATHED IN ACETONE FOR 15 MINUTES FOLLOWED BY A QUICK DIP IN DE-IONIZED WATER. THEY ARE THEN HOT BLUED IN OUR OWN HOT SALT BLUING TANK FOR 20 MINUTES AT 195 +/- 2 DEGREES FARENHEIT. THEREAFTER, THE PARTS ARE DIPPED IN DE-IONIZED WATER FOLLOWED BY A GEAR OIL BATH. EACH PART IS THEN INDIVIDUALLY CLEANED OF BLUING RUST SCALE USING 0000 STEEL WOOL, SUBJECTED TO A HOT WATER-BASED MILD DETERGENT SCRUB WITH A PLASTIC BRUSH, RINSED AGAIN IN DE-IONIZED WATER, BATHED IN WD-40 AND FINALLY DRIED USING COMPRESSED AIR AND LINT FREE COTTON TOWELS. NOT AS SIMPLE AS YOU THOUGHT, RIGHT?

THEREAFTER THE PISTOL IS RE-ASSEMBLED FROM ITS COMPONENT PARTS, LUBRICATED WITH GUN OIL AND BENCH TESTED. CONFIRMATION IS MADE AT THIS TIME THAT THE PISTOL WILL CYCLE AND EJECT SAAMI CERTIFIED, 50 GRAIN FULL METAL JACKET AMMUNITION. WE USED CUSTOM MADE SAAMI CERTIFIED "BLANK" AMMO FOR THIS MECHANICAL CYCLING PROCEDURE. DO NOT ATTEMPT AT HOME.
