Outstanding FB. I say enjoy your grandchildren and cigars/beverages more! You have done your share, and more, so you owe them nothing. You can share your knowledge via writing.
Speaking of skills rusting, just picked up a used S&W 642, real cheap, so I can do very close quarters practice on the range, just for those 'Tueller' situations. Practiced with it today using light reloads and my favorite appendix position holster then, being a practice gun, just stuck it in the gun bag and haven't cleaned it yet.

Thanks. Doing my best. Spent the evening with friends at my cigar club, including another retired cop and his wife (she's still a working cop with 15 more years to go), enjoying a couple of fine cigars.
From a personal perspective, the Centennial style J-frame is one of those quintessential wheelguns that just gets better with age and use.
I own more than half a dozen J's, including a couple of 642's. I also have a couple of M&P 340's (one from their first run, and then a later production no-lock model). I look at the M&P 340's as being sort of an "improved" 642, meaning having a better sight setup and being a couple ounces lighter, even with its PVD blackened stainless cylinder, which can handy for long days of pocket carry.
I always try to keep a dirty J in the safe, so I always have a ready excuse to take one whenever I go to the range.
