I believe that this is normal. From your post "most likely in the air" I assume that you haven't tried it in the air? You should. I do a free fall test in the air about once a month. (slow down, pull the big gear breaker AND the gear relay breaker, gear switch down, open the valve). In ours, I usually need to "help" the right gear a little with rudder. 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.
