There are no known European matchlock pistols and no evidence that they ever existed. The fact that the Japanese made them is no proof that they were used in Europe. The Japanese weren't fools... they recognized how the matchlock worked and their uses for them were almost certainly different than in Europe. If I am not mistaken, at the time the matchlock arrived in Japan there were almost no horses, and hence, no cavalry. The horses had been wiped out in a terrible epidemic - which is why most of the early japanese swords made for mounted use were cut down.
The pistol was strictly a weapon of European Cavalry and the matchlock is singularly unsuitable for use on horseback. I strongly suspect that the reproduction matchlock pistol that is sometimes seen is a fantasy weapon... In that case I agree with Stophel. Accurate shooting was hardly even considered at that time, much less training. The 30 Years War technique for using pistols mounted precludes matchlocks. Essentially, each cavalryman carried two wheelocks. They were intended to ride up to point blank range, fire their pistols and wheel around. Well drilled troops could follow each other, essentially keeping up a steady and extremely ineffective fire. Gustavus Adolphus treated this tactic with contempt. He simply ignored the pistols charged such cavalry with sabers...
Without any surviving examples and not even a period illustration showing one, I see no reason to believe they ever existed. Which isn't to say that someone, somewhere may have made one... they certainly may have but thats like saying that breech loading wheelocks were common based on the example from Henry VIII's collection. Saying that something existed because it could have, when there is no compelling evidence that it did, is not very good history.
Having said all that, the nearest thing to a European matchlock pistol known are the so-called pistol-shields which also date from the reign of Henry VIII. These have been listed in Tower inventories since at least the early 18th century and half a dozen of them are still in the Royal Armouries. No one has any idea if they were ever used for anything and they may just be one of the thousands of goofy inventions that have littered firearms history since the beginning.
Its also possible that someone has confused a petronel with a pistol... a petronel has a very short, pistol like stock that was intended to be held against the center of the chest when firing. These date from the mid 16th century and were made in both matchlock and wheelock versions. It is probably a French word and its meaning in French is fairly clear. However, the word was also sometimes used in English (incorrectly) for a pistol... much like "fuzee" or "fusil" which in French or Italian is simply a gun while in English it came to signify (1st) a flintlock as opposed to a matchlock and later a light flintlock musket.
I'm not sure which illustration from Greener you are referring to. He illustrates both the pistol shields mentioned above and an Indian matchlock pistol. I only have the 1896 and 1910 Editions.
