So every military professional working with a gun 150 years ago was getting a misfire about once every twelve seconds, causing an outright explosion which injured themselves and their allies every 24 seconds?
Really, Lanefan? Really?
This is absolutely ridiculous. This is not realistic. It is not how learning to use a gun works. You can, in fact, mitigate sources of misfire by learning to use it better. Which is what being Gunslinger 16+ means: you are one of the most skilled gunslingers to ever live.
