The result was 9mm cartridge shooting 2mm bullet :s Guns : Blow class 9mm (blank gun) AK-47 Sadam Excuse my bad english No idiots with dumb answers You will have to get a conversion kit or a blank fireing barrel or I COULD HELP MORE IF I KNEW WHAT GUN YOU HAVE

Supplies Needed: Machinists vise Cutting oil Propane or MAP gas torch 1911 barrel, preferably used and worn out Bench Grinder Emory paper Scotchbrite pad Electric Drill Tap wrench ½ inch national coarse thread tap ( ½ inch 13 threads per inch) 27/64ths Drill bit ½ inch national coarse thread cup point set screws ( ½ inch 13 threads per inch) 5/32nds Drill bit # 26 - # 23 Drill Bits (.1470, .1495, .1520, .1540) Allen wrench or bit driver to fit your set screw PermaBlue Dishsoap Toothbrush/Scotchbrite pad Water Q-tips or gun patches

Procedure 1 – Drilling and Tapping the barrel Supplies Needed: 1911 barrel Electric Drill 27/64ths Drill Bit Tap wrench ½ inch national coarse thread tap

½ inch national coarse thread set screw Allen wrench Cutting oil Firmly secure 1911 barrel in jaws of machinists vise, using wood blocks or other non marring material. Take care as to not over tighten the vise as to cause damage, deformation or marring to the barrel. Advance 27/64ths drill into bore approximately 1 inch to 1.5 inches, taking care to not hog the barrel while drilling. A drill press, vise and set of parallels can be used as a preferred method. Cutting oil is to be used during this process. Clear the bore of metal chips prior to threading. Advance the tap into the bore by hand (using tap wrench) taking care as to maintain the tap true to the bore. Occasionally reverse the tap to break any chips as they form. Use cutting oil liberally to flush chips and lubricate the tap during this process. Advance the tap approximately ¾ inch to 1 inch into the bore. Clean threads and barrel. Test fit set screw to ensure proper fit and that the set screw bottoms out slightly below the muzzle. Procedure 2 – Removing locking lugs and tapering barrel hood. Supplies Needed: 1911 barrel Bench grinder Barrel bushing Emory paper 1.) Carefully grind away locking lugs on the bench grinder. Material is to be removed from the locking lugs down to barrel diameter. Taper chamber hood to barrel.

2.) Test fit barrel bushing on barrel. Barrel may have expanded after being drilled and tapped. If the barrel bushing does not easily slide on, use emery paper to remove material from barrel diameter until a suitable fit is achieved. Procedure 3 – Finishing Supplies Needed: 1911 barrel Emory Paper Cutting oil Scotchbrite pad PermaBlue bluing Dishsoap Toothbrush Gun patches or Q-tips Smooth all rough surfaces with emory paper and cutting oil. Pay special attention to chamber hood taper and front 2 inches of barrel. Degrease thoroughly with dishsoap and water. Polish all surfaces of barrel with Scotchbrite pad Degrease the barrel again with dishsoap and water, use a toothbrush to scrub the barrel. Do not touch the barrel with your bare hands or anything oily after degreasing. Apply PermaBlue with q-tips or gun patches, allowing the solution to sit on the barrel for 30 – 45 seconds from first application. Rinse barrel under water after application.

If the finish is spotty or not complete, repeat steps 4 and 5 until the desired finish is attained. Coat the freshly blued barrel with cutting oil. Wipe excess oil off with patches or paper towel. Procedure 4: Drilling set screws Supplies Needed: Propane or MAP gas torch ½ inch national coarse thread set screws 5/32nds Drill bit # 26 - # 23 Drill Bits (.1470, .1495, .1520, .1540) Allen wrench or bit driver to fit your set screw Heat set screws on heat resistant / fireproof surface until the tips are reddish orange in color to soften them, if the set screws are hardened. Secure set screw in vise, using blocks of wood so that the threads are not marred or deformed. Center drill the set screws (preferably using a drill press to prevent hogging of apertures) with the drill bits specified. Start with the largest sizes first. Create a means of marking or otherwise identifying the set screws. A block of wood with holes drilled and threaded in, then labeled, or commercial off the shelf pill containers. Procedure 5: Testing / Troubleshooting Be sure that your 1911 functions properly with live ammo, with your non-drilled and tapped barrel. If your gun has problems with live ammo, don’t expect it to work with blanks either. Install your 1911 barrel, with the barrel link installed. Install the largest aperture set screw in your barrel. Test fire. If the blank fails to cycle the slide, install the next smaller size aperture. Repeat. If the 1911 jams on the blank, or the slide jams, remove the barrel link and repeat above. If your recoil spring is heavily used / old, it may cycle with a larger aperture (154) than the recommended (150). Always use the largest aperture that will consistently cycle your 1911 to reduce wear/stress. There are two types of 1911 blank
