"Yes, a laser engraving machine is very much more expensive than a simple hammer and chisel because of the special equipment, parts and training that go along with using a laser engraving machine."
Engraving is basically carving in metal. An engraver uses a small chisel and hammer to cut lines into the steel of the gun. High quality engraving is done by hand, not by machine, and is done freehand- no mechanical guides.
I have one in 85 to 95 percent condition. A beautiful little SXS .410. i wouldn't take less than $950.00, just because it's unusual and very sweet.
It depends on the grade,hammer or hammerless,damascus,condition of case colors and wood and blueing,etc.Also a bunch of other factors like engraving,length of barrels,how they are choked.I just put $1600 in a 1889 G grade hammer with damascus in good shape...Mike
A single action pistol, such as the 191A1 .45 Auto, requires that the hammer be cocked before the first shot. A Double Action pistol does not need to have the hammer cocked- pulling the trigger causes the hammer to rise and fall. Some are DAO- Double Action Only- the hammer cannot BE cocked, and must be fired from a "hammer down" position. These include the Para-Ordnance LDA pistols.
Turn of the century
A double action firearm requires you to pull back the hammer before you can fire it.
In 1843-- steam raised the hammer, but the weight of the hammer was the only pressure used to shape the metal. By 1888, a double-acting hammer used steam to supplement the pressure exerted by the falling hammer.
