I am of the opinion that making changes in a gun are sometimes dangerous. I know that's a no brainer but how many of us are engineer's of dun design etc. to KNOW that said change in a trigger let's say is a safe thing to do. Down the road there may be something that happens that the change that I made to my trigger fails or causes injury or death. I am only saying this as a cautionary statement. Just be careful in making any changes to your CC, defensive weapons, range guns, or hunting weapons. Your family will benefit and your pocket book will also benefit.
