Model 7s lose some of the ejector/loading port to the over hanging scope mounts. This does make it feel smaller or at least more fumbly for me.

In addition to saving small ears I like a longer barrel for kids that are just learning gun safety, much easier to wave an 18" barrel around and point it where it shouldn't be. A slightly longer barrel might be more awkward but serves as a reminder to keep it down range.

"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
