Barrel and stock are cut . It's modified with a magazine release , bent bolt , and recoil pad . If the type 38 sights are an example of the issue sights the Williams front ramp and rear set are a huge improvement.
I don't know that I have especially unique examples but rather examples that just need a little more than average attention to shoot well .
I like to share the trip , it often helps me sort things out , those "oh yeah I see the problem now that I've written it down" moments . It might save someone else a trip down a blind alley.
