KN, p. 103 “Did you clean your gun this week?”

 

 

 

Are you a recreational shooter or do you use your firearm for self-defense? There is some disagreement even among gun enthusiasts about how often a firearm should be cleaned – anywhere from after every single use to only after 1000 rounds. But, the reason for cleaning doesn’t change: the gun should work when we need it to.

 

Every time the gun is fired, a pin (or hammer) strikes the primer in the bullet and causes a spark. This spark ignites the powder in the bullet and causes an explosion, which moves the bullet down the barrel of the gun. Minute bits of gunpowder and lead residue are left behind in and outside the firearm and builds up over time. Gunpowder dust? Bullet dust? A bit of both. If left on and in the firearm and ignored, the handgun will most likely lose efficiency and reliability.

 

Imagine driving your car for a while without getting the plugs replaced, the filters changed or the oil changed. It might still run, but not as well as if you did the regular maintenance. And, it might even stall (or not start at all) for no apparent reason when you need it the most.

 

Cops on TV and in the movies do have occasional scenes where their guns don’t work and a partner has to come to the rescue. There may be lots of reasons for a handgun to misfire – lousy ammo, worn parts, dirty/rusty mechanisms, blocked barrel, cheaply made – but checking the gun on a regular basis can help avoid some of the common malfunctions.

 

There are three basic rules for safe handling of a firearm, whether you are showing it to someone, shooting it, putting it away, or you are about to clean it, and it’s good to practice them even when you think it’s unnecessary. There are too many accidental deaths caused by people cleaning their firearms, so please take note:

1 – always point the gun in a safe direction

2 – keep your finger OFF the trigger until you’re ready to shoot

3 – keep the gun UNLOADED unless and until you’re going to shoot

 

When you buy the gun, pick up a cleaning kit at the same time. Cleaning kits are not expensive – $20.00 will get you a basic kit that includes the metal rods and brushes you need to clean your handgun, along with cleaning patches and patch holders. There are several types of brushes to use, but most gun owners say that a toothbrush will work to do the overall initial cleaning, and twisted bronze brushes will work best for cleaning the bore. The bore brushes come in different sizes to fit the different caliber guns. A bore brush for a .45 won’t fit a .22, etc. Check the manufacturers catalog to see which brushes you need, if you don’t already know.

An interesting tool for cleaning a firearm is a Bore Snake.

Bore Snake   

Because of its construction, it is possible to combine a couple of cleaning steps into one. The two ends (of what is essentially a very fat shoelace) are softer, with bronze bristles in the center. As the Bore Snake is pulled through (from back to front) of the bore, the soft end removes loose residue, the bronze wire on the Bore Snake loosens the more resistant grit, then the softer floss at the end pulls away the rest. It can be used with solvent, or pulled through dry.

The Bore Snake can also double as a safe storage and transport aid. If the Bore Snake is in the bore, there’s no possibility that a bullet is in the chamber.

 

Steps to cleaning the firearm:

1. Check to make sure that the gun is unloaded.

2. Take apart the gun.

3. Wipe down all the parts to be cleaned, using cloth rags.

4. Apply a solvent recommended by your gun’s manufacturer to the dirty areas and let it sit for 2-3 minutes.

5. Scrub the entire gun, inside and out, with a soft brush to loosen the grime.

6. Wipe the gun clean with a solvent-soaked rag and repeat if necessary.

7. Use a bore brush (or the Bore Snake) to clean the bore, being careful to start at the back and move forward through the bore, without reversing direction while inside the barrel.

8. Use the solvent to clean the bore with a cotton patch or the Bore Snake.

9. After cleaning the gun, lubricate it.

10. Grease the sliding parts of the handgun.

popular cleaning supplies

There are different oils and greases used during extreme weather (hot or cold) as well as in wet, humid conditions, so check with the gun manufacturer to see which product(s) will work best for your firearm.

 

 

Some military rifles are built so that cleaning supplies can be stowed in a special compartment in the stock.

 

We hear every once in a while about people shooting themselves while cleaning their firearms, sometimes with deadly consequences. It would seem impossible for these tragedies to occur if following standard gun safety rules, but sadly, people don’t always do that.

The best policy is to assume the gun is loaded and check each and every time before you clean it, to make sure you don’t shoot yourself or somebody else.

KN, p. 71 “Whose fingerprint is that?”

 

I watched one of the CSI NY television episodes last Friday and was struck, yet again, by the Hollywood look of their crime labs. I like the show because of the actors and some of the cases, but as I’ve said before, TV sets and real life investigations bear little resemblance to each other – not in time, or equipment, or budgets. But, the viewing public expects the local police departments to have all that equipment readily available and is upset with the super long wait for results. It’s called the ‘CSI-effect’ and the guys and gals in real-life law enforcement have to deal with it all the time.

 

In the real world, investigators and examiners prove a case against the possible suspects using proper evidence collection techniques and tools, with hard work – not flash results in 50 minutes.

 

Fingerprint powders, brushes and magnifier

 

Fingerprints found at the scene are still the favored piece of evidence tying the suspect to the crime. These days, using a combination of ingenuity and newly developed chemicals and powders, a crime scene investigator can lift (and/or photograph) prints from many previously challenging surfaces.

 

After dusting for prints with black fingerprint powder,

they can be lifted from various smooth surfaces using (in forefront) a gel lifter, a hinge lifter and (in background) tape.

Prints are photographed and then can be viewed under an Optical Comparator. This machine can be hooked up to a laptop, and the image sent off to AFIS for ID.

We hope for a complete print, but the usual occurrence is that most of the time, partial prints are left at the scene. That’s what makes the search for the suspects so much tougher than what the TV dramas tell us. There is no instant ‘a-ha’ moment that comes right after the crime has been committed. In a real lab, AFIS comes back with a list of 10-20 possible matches and someone then makes a comparison by hand of the most likely hits.

 

Some things to keep in mind:

 

*A print can disappear over time and there are too many variables (temperature, humidity, condition of the surface, etc.) to predict how long that will take.

 

*A really crisp print can be photographed right at the scene, using some great digital cameras now available.

 

*Forensic science is not a certainty, even though TV shows may give that impression.

 

*There is no nationwide standard for number of points of ID for a fingerprint. In the year 2013, the acceptable number of matching points (between the actual print and the print in the AFIS database) can range from 5 to 20 depending on where the suspect lives.

 

There is no such thing as a perfect crime, but the jails are filled with crooks that swear they have been framed. One of my favorite excuses: “Somebody planted that print.”

 

Right.

 

That only happens on TV and in the movies.
