Yes, the nose should be first to lock. If it's getting lazy, you're probably due for a new gas strut. This is a normal maintenance item, I replace mine probably every 3 or 4 years. If you replace the nose strut, time the extension with the new strut. That will give you a baseline number so that you'll know when it's starting to get weak.
