The latter procedure requiresdrilling the bushing (made of high carbonsteel) to i'. good linear fit on the disconnector,then reaming from the bottom with ataper reamer until the disconnector operatesproperly under slow and rapid fireconditions. It's all a case of "cut and try."Mainspring housings are often too large,requiring only judicious stoning, butsometimes will be found to be so undersizethat they rock in the frame, giving a mostinsecure feeling when firing. There are severalsolutions. The most common one is toresort to the flat end punch to displacemetal in several spots over the length ofbearing, then to stone to a good sliding fit.Often, the grip safety will have to be filed,to allow the hammer strut to clear after thisdisplacement.A grip safety may vary in many ways.Some will not allow the trigger to trip thesear; others are too loose and require aspot weld to build up length. The too-longvarietycan be stoned, a few strokes at atime, until the spring sets the safety easily,without allowing any perceptible play. Thestepped portion may require some stoning,to allow.the trigger to trip the sear. Thismay be changed somewhat when the hammerand sear are stoned into good contactto provide a decent letoff. Always do thatportion of a trigger job first; it will saveproblems and expense later.SPRINGS WEAKEN WITH AGEMagazine catches sometimes are oversize;these will require stoning until theyproduce a free fit in the frame. Depress thecatch button and make sure it does notbind in its extreme position. Catch springsweaken with age, so it is best to solve theproblem before it presents greater ones onthe range, or on the street.An undersize magazine catch lockshould be discarded and replaced. Undersizelocks have a nasty habit of workingloose during firing.Thumb safeties require extensive stoningand polishing to fit properly to someframes. The detent face may require filing,stoning and polishing before the safetyworks properly. Internally, it should lockup securely without any perceptible extrapressure having to be exerted. Alwayscheck the thumb safety with the slide onthe frame.Slide stops often require a small dimplewhere the plunger contacts the face in thedown position, to prevent its working upwith rounds still in the magazine.Continued on page 60MISSOURI RESIOENTS: 1·314·343·3515SHARE YOURINTEREST INSHOOTINGTELL A FRIEND ABOUTRANDGUNNERMAGAZINEBetter yet . .. givethem the enclosedsubscription ordercard.AMERICAN HANDGUNNER· MARCH/APRIL 1983 21
