Wow! I field stripped my Mark III tonight for the first time. It took me an hour and a half. What a pain in the ass!!!!! What a lousy break down design. Don't get me wrong, I absolutely love this pistol. Real quality! But damn! What were they thinking? You really have to watch That stupid swinging pin inside the handle that a little bigger than a needle. If that thing isn't in the right position, you'll never get the thing back together. My wife and I watched several YouTube videos until we finally found one which explained all that. Then bam! It finally worked. If you have one of these, this video will save you a ton of time.
