There are (at least) three different items that might be helpful.
1) The Gunsmither brand "Pistol Pal" tool that hpman66 linked to is also available directly from the maker. Not necessary, but might be handy.

2) "Hammer Strut Support" is likely what Busterswoodshop is referencing. Also not necessary, but one less thing to watch during reassembly.

3) Majestic Arms "Speed Strip" kit is another related item. Once installed, the kit introduces the requirement of a tool for disassembly. :x
The basic MK can often be disassembled w/a fingernail, once pistol has been broken down a few times.

Study the manual, and practice until you are proficient. "It's not that hard," but can take a while to "get it." :mrgreen:
