Ah, the classic urban legends about how terrible the Indian guns are and how totally reliable the Italian ones are...love it. Take a read of this:

Pay particular attention to the link on the "autopsy" of the weapon that failed in the infamous 2007 incident..which was not a mechanical failure or unsafe workmanship issue, but rather human error...also look at the actual mechanical failures noted with the Italian pieces...
Now, with the "safety" issue at least given another voice and some actual empirical data, we can move onto historical accuracy, which the Italian ones are, quite simply, horrible. Read any authoritative study on weapons of the American revolution and you'll see just how "off" the Italian muskets are...and, oddly enough, how much closer to reality the Indian ones actually are.
Stop the hate, stop the urban legends. I've had my own musket tested by our armorer and outsourced to a professional one, with absolutely no issues detected. The bottom line is do the research and stop passing along urban legends. If you've "seen" multiple failures, post the pics and the details of the post-incident investigation, otherwise your putting out legends.
Take the time to take care of your weapon and ensure you are operating it safely. Don't think simply paying twice as much for a musket is going to get you one that is absolutely safe, nor is it going to get you any closer to historical accuracy, but rather farther away. DO THE RESEARCH.
Sorry, soapbox is now free...
