Update:
I finally got around to cleaning the Girsan. It was filthy dirty and dry as a bone. I mean, there wasn't a hint of lubrication on the pistol. I had soaked it generously in G96 before the test but my daily dry fire and handling of the gun, coupled with the 1260 rounds resulted in no lube to be found anywhere, which was a little odd.
Here are some pics:
The rails have some wear marks, which I don't have on my Beretta, and the Beretta has many more rounds through it:
After it's dirty dirty photo shoot, I soaked in in G96 for 24 hours and cleaned it. I didn't remove the extractor and clean it because 1200 rounds should not be enough to dirty the extractor enough to cause the erratic problems I was having. I lubed the heck out of it and then shot it on a pistol course I attended last weekend. I put 300 rounds through it on the first day without any problems whatsoever.
Conclusion: I think the Girsan is a solid pistol. I like the size of the gun. If Girsan lost the finger humps, did some front and back strap checkering, made it a G model with a replaceable front sight...they would have one hell of a carry/competition gun. It likes to be wet, as most Beretta's do. I think my aggressive dry fire schedule, coupled with the lack of cleaning, caused the gun to become too dry and that caused the problems. I tend to believe that despite the filth, if I had simply lubed the gun every thousand rounds or so, it would still be chugging along. I think the rail wear on the gun indicates a tighter frame to slide fit than the Beretta, which tends to be unforgiving of light lubrication.
