It is done. Thank you everyone for the encouragement. In fact, an untrained monkey with minor skills CAN do it themselves. Came Thursday and I put it in today. Took 1 hour and 8 minutes including opening the packaging and rummaging for tools at times. It was pretty easy, the only delicate part being to get the safety, hammer, and transfer bar all lined up at once on the hammer pivot pin and seated...took a little moment of holding my mouth right. It would help to prepare beforehand to have a pistol clamp or rest to hold the lower, and to have the proper screwdriver bits ready to go. Take it slow and patiently and read every step twice before you do it. And for gosh darn sake, listen to the Volquartsen guy doing the video and adjust the takeup and overtravel trigger screws before you place the trigger into the frame...i was working off their printed instructions, even though I watched the video once a couple days back, and once everything was together I realized the screws were almost all the way out and I had to slowly turn them in a 1/6th turn at a time because it's tight spaces in that trigger guard.
Trigger is now 2.4 ozs and short pull and consistent instead of its previously variable 4.5-5.5 lbs and lots of overtravel. The only thing I'd do different is use the thicker of the two trigger bushings of the kit. I used the thinner one and there's just a touch of side to side play left.
And good riddance magazine disconnect!
