For months, probably close to a year, I avoided taking down my 22/45 because everyone told me how tough it was. The store that I bought it from wouldn't even show me how to dissasemble it (a first for them) since everyone would come in with a bag of parts, and they would have to fix it.
Finally a few months ago, the pistol had goten dirty enough that it would barely go through 2-3 mags without a jam. So I finally broke down, and broke it down.
I think the first time was tough just because it was a little tight, and because I was intimidated by everyone saying how tough it is.
It's really no big deal. The trick is holding the pistol at a certain angle during certain steps.
When you are installing the mainspring into the reciever, point the pistol to the floor, and when you are ready to close the mainspring, point the pistol into the air. If you do that, than everything will be in the right position.
As for having to use a mallet to remove the bbl from the frame, it shouldn't be that tough to remove. The first time for me I had to do that, but since then I can just pull it off.
I think if any of my friends get a 22/45 or mkII or mkIII, I will have them shoot 500 rounds or so before I show them how to dissasemble the pistol, just to have things wear in and loosen up.
