Barrel length? What matters to me is how the gun feels when held between my hands, comes up and swings to the target that matters.

But then, I've never been worth a darn at shooting a sustained leed. If I can't shoot paint or pass through, then I save the shell (cause I know I'll miss).

As to rifle ctgs, they all have there place! You are welcome to use the same line with your wife. All I know for sure is, it's worked for me for the past 33 years.
