They are a lot of fun. I don't shoot mine as much as I used to. The sights can be difficult at times for my 49 year old eyes.
I recommend pulling the firing pin and spring and check for rust. I pulled mine and that's what I found. I also had the incorrect firing pin retaining pin installed. I got the correct retaining pin and replaced the firing pin spring just this week. I need to get it out and give it a test run.
