Even though mine had a claw that was positioned in such a way that it could become ingrown, a simple nail clipping on a regular basis resolved it nicely.
If you start touching his paws now in a casual way, he will handle the clipping well. I used to sit mine on my lap (back feet out and his back aagainst my stomach) and count each toe on each foot. Splaying the toes slightly as I counted. This got him used to my handling his toes, so he never really noticed when I started adding the clipping to the process. I have since done this with all my cats to simplify the clipping process - only my current one has issues and that's because he can't stand being still for more than 2 seconds at a time.
