It's pretty obvious that many people here do not know what "BBQ Guns". Here's an excerpt from "The Texas Lawman" column:
"Now, a BBQ gun is a whole different animal. A BBQ gun is what you wear to barbeques, baby christenings, formal balls, and any other place where a fancy jacket or outfit would be worn.
Get your paws on a revolver. Smith & Wesson or Colt would be best, although I understand that Brazilian products are becoming accepted. Polished stainless at a minimum, and full-blown nickle is a better. And pony up for full engraving. Have the trigger, hammer, screws and ejection rod anodized blue, gold, or colour-case-hardened for the traditionalists.
Now, look in the mirror. Is your mustache over 50% grey? If so, go for pearl grips. 49% or less on the grey-meter, and you'd best stick with ivory. If you go for mother-of-pearl, have it carved or inlaid. Steer heads are a classic pattern, although badges and stars are always safe.
If you go the ivory option, have the ivory inlaid or scrimshawed. Floral patterns involving roses and the Texas flag are good, as well as the state of Texas, a tasteful rendition of a young lady, or long horn cattle. Any scene from the battle of the Alamo is a surefire crowd pleaser. For those souls living outside the Great State of Texas, the flag raising at Mt. Suribachi may be substituted for an Alamo scene, and anything involving Marines is acceptable engraving material.
I would advise that you stay away from morbid or dreary themes in your engraving -- unless it is extremely well done.
The leather for your BBQ gun should be of a floral pattern, with the engraving a different color than the rest of the leather. The engraving pattern should extend to the buckle and any other metal hardware which should consist of silver and be polished bright enough to shave in, although gold is acceptable if carried with the proper attitude.
Accessories should be limited to a reload and a pocket watch.
No BBQ outfit is really complete without hand-made boots made from the hide of a critter that is guaranteed to send your local PETA petter into orbit. Pressed jeans under a Western-cut jacket, with a bolo tie, and a black Stetson complete the ensemble. The bolo tie should have a chunk of rock slightly larger than a baby's fist and the Stetson should have a hat band made from the cousin of the critter on your feet.
For some of the best examples of court and BBQ guns around, I strongly recommend visiting the Texas Ranger Museum in Waco, Texas."
The definition of a BBQ gun was very extensively discussed a few years ago on the Colt Forum:
Colt autos (1911's or 1903's also qualify and so do Hi-Powers --if from browning!). Firearms are made from METAL, not plastic! Highly polished blue or case-hardening will work at a minimum for a finish. No synthetics for grips==pearl (real), ivory or exotic wood only. Wolf and Klar engraving gets extra points. Caliber must start with a "4" (except for Colt 1903s) or "357"=must be of a sufficient caliber to provide the dinner. Extra points if: Your boots and belt match your holster; and you got the gun from a man trying to kill you!
