Louis-François Devisme was known for his exceptional quality firearms during the 19th century, which are highly sought after, even today. He received numerous awards over a thirty-year period, from his first award for firearms design and manufacture at the 1834 Paris Exhibition of Industry including a medal at the Great Exhibition of 1851 in London (also known as the Crystal Palace Exhibition) for firearms that he displayed there. Between 1858-1859 he produced a very advanced center-fire handgun that was based on an earlier percussion design and was in all probability the first designer to utilise the “striker fired” handguns, a concept still used by Glock amongst others.
