I'm one of the lucky few that's broke a pin haha, have to concede that it was me, not the guns fault. Picked the gun up in February, and didn't get to the range till April. Probably dry fired 2000 plus times in practice like you mentioned. Somewhere in all that I noticed only once that when I racked the slide it didn't reset the trigger, and I think that's when it broke the pin. I thought breaking firing pins was a thing of the past, I was wrong, haha. I got two new ones for less than $20 shipped, and she's running fine now. RonMar and others have good advice on the rfb, she is a different animal than your used to, but fun to learn.
