Other than field stripping and cleaning I've never dismantled one of my 1911's Colonel. I've read that most of 1911 plunger tubes are staked on, but I have no idea how to release the nibs on each end to get to the spring. I guess a youtube search is in order. I would very much like the safety to be more positive. One bright side I guess is there was very little chance of picking up the dreaded idiot scratch when I reassembled it last night, and my mag release/disassembly lever isn't even notched like they are on my DW's. But still I'd opt for a positive safety click over less of a chance of scratching this gun.

I did have it in the back of my mind when I was shopping for a Tisas that they might be a good gun/opportunity to become more familiar with the innards of a 1911. It is a series 70 just like the DWs. So if I do pull it apart at some point at least I may be in a position to use the experience on one of my others if the need arises.
