If you are mechanically inclined and have the correct size screw drivers, you should be fine. Might want to watch some youtube clips on the process to help you determine if you are up to it.

If you intend to get involved in S&W's at a detailed level, which I would advise if you are mechanically inclined, I would recomend you purchase Brownells Magna Tip screw driver set and don't skimp. If you do it, buy 58 piece set.

You will very very likely be fine with no internal maintenance, but I feel it is worth while to know how to remove a side plate and be familiar with the internal lock work.
