I've had mine for over TWO years
Thus far, mine has approx 700-800 rounds through it, primarily Winchester Silvertips, Fiocchi 73 FMJ's and CorBon 60 gr JHP's. I have had only ONE malfunction: a fail to feed with one Fiocchi FMJ.
My serial is 035xx........don't know what they are at at present.
Mine is absolutely box-stock, other than polishing the feedramp.
I keep thinking about selling it but cannot bring myself to do it because it is easily the most comfortable and concealable gun I have.
Yeh, it's a keeper, until someone comes alone with a smaller, lighter, more powerful item and that's probably not going to happen.
