Most guns are pretty easy to clean some do clean quicker than others. Sidelock guns clean up pretty easy until you have to clean the lock which requires removing it from the gun. Inlines also clean easy for the most part. A few have bolts that need to be taken down and if you ever did that on a bolt action rifle you know what a pain it is. My Encore is real easy to clean but I have to remove the barrel because I am to cheap to buy the folding extractor that came out last year. I have been told the Omega's clean up real easy too.

I own an old T/C Scout that cleans up easy too. It breaks down into three groups of parts that by themselves clean very easy. Less than an hour tops on all guns that I know of once you get use to them.
