I HAVE HAD THE OPPORTUNITY TO "MATCH-PREP" TWO OF THESE SEARS & THE FIRST THING I NOTICED, WAS THAT THE PIN HOLE WAS DRILLED PRECISELY @ 90 DEGREES SQIARE TO THE SEAR NOSE & THUS THE PRIMARY ANGLE WAS VERY EASY TO ACHIEVE, BECAUSE THE SEAR WAS PERFECTLY ALIGNED TO THE CENTER OF MY STONING/POLISHING JIG !!!!!! THEN WHEN THE SECONDARY BEVEL WAS STONED, THE FLAT AREA WHICH THE INTERNAL THUMB SAFETY TAB RESTS AGAINST WHEN THE SAFETY IS ENGAGED, THAT SURFACE WAS ALSO DEAD-NUTS FLAT TO THE SEAR NOSE. THUSLY THIS SEONDARY ANGLE WAS AS EASY TO ACHIEVE AS THE PRIMARY ANGLE WAS !!!!!!! THIS IS A RARE OCCURANCE, BUT IT PROVES THE QUALITY OF MACHINING DONE TO CREATE THIS QUALITY OF SEAR---WOW !!!!!!

CLOSELY EXAMINED THIS SEAR UNDER 4X MAGNIFICATION & DIRECT LIGHTING. COULD NOT SEE A DEFECT OF ANY SORT. MACHINING, GRAIN STRUCTURE, & POLISHED BLUED FINISH WAS SHEAR PERFECTION. I CHALLENGE YOU TO FIND ANOTHER PART @ THIS PRICE POINT & THIS LEVEL OF QUALITY---ATTA-BOY "FUSION FIREARMS" !!!!!
