You mkay want to look at this thread http://www.calguns.net/calgunforum/a.../t-253494.html
I don't quite understand it, but one person seems to be saying that the problem with some older Mossbergs was a combination of a floating firing pin and a disconnector? I think the problem was that they would fire if racked hard while the trigger was held back (slam firing). If that is true, I don't know if you need to worry about an accidental discharge if the gun is dropped, since the trigger will not be held back, but I am just guessing. There are some guys here that really know Mossbergs and maybe one of them will chime in. Harddog wait to here from Hogdogs (Brent).
