I actually spoke to someone at the company that produces the one (of several designs and manufactures that can and will do this, there are a few) today. (Of which is not well known apparently as little was issued about it,) they seemed genuinely concerned and eager to correct the issue as well as ease my apprehensions. (despite what I had read from some fairly professional sources,) They explained the conditions in which this can happen, that older versions were more likely to do this (I have an older one,) and would gladly take it back to fix it. I guess it has to do with either 1: a spring not functioning properly due to a lack of tension from wearing out and or 2: a firing pin becoming stuck from abuse that lead to the hole the firing pin comes through enlarging or being so gummed up it sticks. I was told the newer versions have a firing pin hole that was redesigned so it won't gum closed and is made of better materials so whatever pressure it deals with will almost never enlarge. I was also told however that if it is an issue with the spring that loses tension, it should be replaced immediately and what to look for to determine if the spring needs replacing. Regardless, while I am feeling better about the gun and design itself after knowing some of these things... I intend to take it to the range and test a few conditions and things, replace anything that needs it, and ensure it's safety as anyone should. I guess the moral of this story is one should fully research as much as possible before making a used gun purchase... one doesn't always think to do this. The only reason why I bought it (well ok not the ONLY,) was because years ago I had one (newer version that didn't have these issues,) and regretted getting rid of it.
