I got my Sistema 45 this week. It came from CDNN through a dealer I use. Upon seeing it, I was a little disappointed. The finish was not as good as I expected. Also, the magazine that came with it was useless. So, I grab the magazines from my Springfield and take it out to see how well it shoots. It did fine with the 1st magazine,except for the hammer bite. After the 1st round from the 2nd magazine,the firing pin stop came out causing a jam. I boxed it up and took it to my dealer. They are being good enough to fix it for me. What I'm wondering is, are these Sistemas inherently unreliable? Are they prone to things like this happening? Should I ditch it and stick with my Springfield?
