Don’t know how collectible these are, but I like ‘em...
S&W, model 24-3, .44 Special, 4” barrel, mfg. 1983-1984 - 2,625 manufactured. Awesome revolver, very fun to shoot.
S&W, model 610 (no dash), 10mm, 5” barrel, mfg. 1989-92 - 4,560 total manufactured, 5” barrel numbered around 2,000 or so (if anyone knows the exact number, please let me know). Hands down the best, most accurate, most fun revolver I own. If you’ve ever shot a 610, especially in the 5” barrel, you know what I’m talking about.
