Well,
I learned something today. Actually several things.
One, You should occasionally check the screws in your guns and make sure they are tight.
Two, There is a reason you wear eye protection.
I was firing my Blackhawk yesterday when it decided to break on me. I was shooting my regular 255 gr, 8.5 gr Unique loads. I was left holding the grip while the rest of my gun went past the line into the shooting lane. I was actually alone on the range and I used a broom to retrieve it.
The gun was built in 1995 and the previous owner did warn me that he liked "hot" loads in it.
I suspect that the screws holding the grip frame had worked loose. I have a Marlin 1894 that is notorious for doing the same thing.
From now on I will double check things like that. Even at 61 years of age I still learn new things.
The next new thing to learn is the confusing history of Ruger grip frames and how to replace one.
