I have a Spiller & Burr that I built from a kit.
It turned out very nice if I do say so myself. :grin:
I haven't shot it a lot but it did work with a 18 grain load of FFFg and .375 dia roundballs.
I didn't notice any problem with the grip and trigger guard but these .36's don't kick very hard. Maybe if my hand was larger I might have noticed it?
The only thing I consider as a weak point is the screw that connects the ram to the loading lever is a very small diameter screw and it doesn't look like it could take a real heavy load without sheering. Because of this I wouldn't consider using a pistol bullet in the gun but it does seem to work alright for loading roundballs.
Another thing that leaves a bit to be desired is the cylinder axle release. This is a small screw located on the left side of the frame. To remove the cylinder bolt, the screw is turned 180 degrees (only) which aligns a notch in the screw with the axel to allow the axle's removal.
If this screw isn't positioned correctly, the cylinder axle (to which the loading lever is attached) may pull loose from the frame.
The Spiller & Burr has an interesting history.
As you may know it is patterned after the .36 cal Whitney (a steel framed revolver).
When Spiller & Burr contracted with the Confederacy to make 15,000 pistols the contract very clearly says the gun will be "substantially of the Colt's pattern".
The answer to this substitution of a Whitney Copy for a Colt copy seems to be that another company called the Robinson Revolver Factory in Richmond, Virginia had tooled up to produce a copy of the Whitney for sale to Virginia but never produced any of the pistols.
When Spiller & Burr established their company in Richmond. Virginia, they apparently bought the tooling and designs from Robinson however they never produced any known pistols at that location.
They moved the equipment to Atlanta, Georgia and produced about 700 pistols there.
Because they were so far behind in their delivery the Confederate Government bought them out lock, stock and barrel and moved the resulting company to Macon, Georgia where over 600 pistols were manufactured.
The total number of Spiller & Burr pistols during the war was about 1,400 or less than 10 percent of the number the original contract specified.
