Accessories can only be installed in specific locations. Take a closer look. This kind of thing is not very complicated. You can go to the movie "Three Guns Surprise", in which there is a passage where foreigners load gunpowder. See if it is. I can't describe how to install it, but I am in my mind.

In fact, the original name means "revolver", which has nothing to do with left and right. The runner design of revolver pistol is earlier than the flintlock era 17 18. 1835, American colt improved the previous design and obtained patents from Britain and the United States. Unlike all other firearms, the barrel and bore of a revolver are separate.
1835, an American Colt improved his predecessor's design and obtained patents from Britain and the United States, because Colt's sales skills were excellent and the United States was not as secretive as Europe at that time.
State-owned or monopolized private armories monopolize all new gun technologies, so that Colt can spread all over the world with his name, so that later generations equate him with a revolver, and Colt is even mistaken as the inventor of the first revolver.
At that time, because of patents and secrecy laws, different manufacturers often invented similar designs independently. Some gun factories were forced to give up the market closure because they could not afford the patent right or could not wait for the patent right to expire, which made the public misunderstand who was the first inventor.
