INSPECTIONS
Section I. GENERAL
11. scopeThis chapter provides specific instruc-
tions for the inspection by maintenancepersonnel of materiel in the hands oftroops in the field, in .Ordnance shops,and in alerted units scheduled for overseaduty. Troubleshooting information is in-corporated wherever applicable as a nor-mal phase of inspection.
12. Purpose of Inspection
Inspections are made for the purpose of(1) determining the condition of an item asto serviceability, (2) recognizing condi-tions that would cause failure, (3) assuringproper application of maintenance policiesat prescribed levels, and (4) determiningthe ability of a unit to accomplish itsmaintenance and supply missions.
13. Categories of InspectionIn general, three categories of inspec-
tion are performed by direct and generalsupport maintenance personnel.
a . Inspection ofMateriel in the Hands ofTroops.
(1) Spot check inspection. This is aninspection performed on apercent-age of materiel in order to ascer-tain the adequacy and effectivenessof organizational maintenance andsup ply. Included within th is scopeis inspection of equipment to detectinc ip ien t f a i lu re s be fo re un-

a final inspector after repair hasbeen completed, to insure that themateriel is acceptable for returnto user or storage.
c. Preembarkation hspection ofMate-rielio Units Alerted for OverseaMove-ment. Th i s~ inspection is conducted onmateriel in alerted units scheduled for
oversea duty to insur e tha t such ma terwill not become unserviceable or worn oin a relatively short time. It prescriba higher percentage of remaining usablife in serviceable mate r i e 1 to meetspecific need beyond minimum servicability.
Section II. INSPECTION PROCEDURES
14. General
Wamfng: Before sta rt ing sn inspection,be sure to clear the weapon. Do not actuatethe trigger until the weapon has beencleared. Inspect the chamber to insurethat i t ie empty and check to see tha t noammunition is in position tobe introduced.Avoid having live ammunition i n the viom-ity of workarea.
a. Check to see that the weaponhas beencleaned of all corrosion preventive com-pound, grease, excessive oil, dirt. or for-eign matter which might interfere withproper functioning or obscure the truecondition of the parts. b. Make an overall inspection of the
weapon for general appearance, condition.operation, and manual functioning. Usedummy cartridges.

The followingmeth-ods and procedures given in this chapterar e to be car efully observed dur ing repa iropera tions. This cha pter includes t he dis-assembly and assembly procedures, re-placement of par ts , use of tools, cleanin g,finished surfaces, removal of burs. andtns t ruc t ions on lubrication.13. General Repair Methods
a. Disassembly and Assembly Procedures.(1) In disassembling a unit, remove
the major subassemblies and as-semblies whenever possible. Sub-assemblies may be disassembled,as necessary, into individual parts .
(2) During assembly. subassembliesshould be assembled first, theninstalled to form a complete unit.Lubricate all component partslightly before assembling.
(3) Complete disassembly of a unit isnot always necessary in order tomake a required repair or re-placement. Good judgment shouldbe exercised to keep disassemblyan d assembly operat ions t o amin-imum .
b. Replacement of Parts.0)
(2)(3)
When assembling a unit, replaceall pins when necessary. Replacegrip screws or bushings whendamaged.All spr ings will be replaced if theyare broken. bent, cracked or if theyfail t o function properly.If a r equired new part is not avail-able, a reconditioned used partmay be substituted. Such recondi-tioned used parts will be examinedcarefully to determine their serv-iceability.
c. Use af Tools(1 ) Care must be exercised to use too
that fit and are suitable for the tasto be performed in order to avo
unnecessary mutilation of parand/or damage to tools.
(2) Special tools are listed in t ab leand are provided for the maint
nance of the m at eriel. These toowill be used only for the purposfor which they are intended.
(3) Keep tools clean and work wiclean parts. Normal rules of goohousekeeping must be observed.
19 . Cleaninga. As assemblies are removed and di
assembled, component items should bplaced in a wire basket a nd cleaned t hooughly of all grease, oil, water and dirusing dry cleaning solvent (SD). Dthoroughly with clean wiping cloths anoil lightly us ing general pu rpose lubricaing oil (PL special).b. Clean the barrel bore, chamber, an
all parts that come in contact withpowdresidues, using solvent cleaning compoun(PD 126). Cleaning rod IvI4, 5564102 (fi4) and small arms cleaning brush M5504036 (fig. 4) are used to clean thbarrel bore. Saturate brush with PD 12and run through barrel. Remove brusclean the rod, insert two swabs in slot rod and dry the bore thoroughly or untswabs appear clean after running througbore. Then use one swab saturated wiPL special t o oil inside of bore lightly anall exterior surfaces to prevent corrosioor rust.
c. On those component parts whichcota in a ha rd carbon r esidue, it ma ybe neessary to clean these parts with carboremoving compound (P-C-111A). Cleaniinstructions are as follows:
Warning: Avoid skin cont act. Th e compound should be washed off thoroughly wiru nn ing water if it comes tn contact wi

FINAL INSPECTION
39. General
Pistols turned in for repair may beassu med t o ha ve defects caus ed by use orneglect. When th ey were a ccepted a s newweapons, th e par ts composing t hem weredimensionally correct and made of theproper material. The inspection of theseweapons after repair will differ from theinspection procedure used in the manufac-turing plant in that at t e n t ion will bedirected to wearing surfaces, parts thatmight crack or break due to high stressor fatigue, and evidences of corrosion.
These defects do not evidence themselvesby uniform reduction in a given dimensionbut show up as a chipped edge, a partiallyworn sur face, or an eccent ric hole. Agageused in man ufactu ring is merely a meansof comparing an unknown dimension with aknown one to judge whether a piececomeswithin tolerances. After this piece is wornthrough use. the change in dimension ismore easily detected in many cases bycomparing with adjacent, surfaces; thepiece in itself becomes a gage. Visual
inspection, therefore, is far more applic-able in these cases and gaging is limitedto those dimensions that are critical orthat may be more advantageously meas-ured than compared. Inspection of non-critical par ts (part s th at do not ordinar ilycau se ma lfun ctions) will be limit ed t o ap-pearance and the presence of cracks orflaws. The dimensions and tolerancesplaced on the parts (and gaging used duringmanufacturing) were for the sole purposeof insuring interchangeability. Even if the
dimensions of such parts are worn oon-siderably below drawing tolerance, func-tioning and inter cha ngeability will not beadversely affected and the parts are con-sequently aoceptahle. The serviceabilityof the material must also be determinedby conducting inspection as described inparagraphs 13 through 16.
40. Specific Inspection Proceduresa. Visual Inspection. Visual and overa
appearance of the pistol should be approxma tely th at of a n ew weapon. All exposemetal surfaces are to have a phospha t efinish. The color will range from black tmedium light gray. Bright surfaces arobject iona ble from s ta ndpoint of visibilitwhen th ey ar e capable of reflectin g lighAll outside surfaces will be free of bu ror deep s cr a tc he s. Barrels must bstraight, clean and free of rust andpowdefouling and free from bulges and ring
Pistols must be complete. All applicabmodificat ions m ust be applied. The ser inumber must be legible and allparts mube free of rust. Visually inspect the following:
(1) Check front an d r ear sight s, makcerta in they are t ight andpr opera l ined .
(2) Check for split or d am agedplastgrips and loose grip screws.
b. Functional Znspection.(1) Check functioning of safety. Refe
to paragraph 15c(l).(2) Check functioning of grip safety
Refer t o paragra ph 15c(2).(3) Check functioning of hammer o
sear. Refer t o par agraph 15c(3).(4) Check functioning ofdisCOMeCtO
Refer t o paragra ph 15c(4).(5) Upon completion of inspection, pi
tols will be properly cleaned anlubricated , (gara$raphs 19 and 23
