Sorta wish my 3" was a 65, make a cleaner carry without the adjustables, but it carries well anyway. I have a 3' and a 4" 66, super accurate guns and of reasonable high qualtiy regardless of the detractors. They're working guns, the 3" a carry option and the 4" an outdoor/hiking, etc gun. Both were bought used, the 3" an 80s era gun and the 4" a early 90s era gun with the transfer bar trigger (vs earlier hammer block), but pre lock/pre MIM. The lock on a Taurus doesn't bother me, much better design than Smith's frame hole, and the MIM wouldn't bother me, either, don't think, though I don't own any guns using MIM parts. All my Smiths and Tauri are used. Bought one M85SSUL new in 1996, has the lock, but still pre-MIM. I am carrying it as I type this. It's also a fantastic shooter.
Buy face to face and put the gun through the check out procedure is my main advice.
