Hi
There are so many horror stories about Tanaka and broken barrels.
I will not claim I have fired my early version cartridges a lot but I have used them, also in my several years old USP. So far I have escaped unharmed by such disaster. In the ? 3 years old G18 I have shoved through around 40-50 rounds of early version cartridges on Auto
I have become more and more careful about cleaning and lubrications. Not saying that’s why - I might just have had luck (until now
)
