I have had the 85 UL, 605, and 856. I had over 7k rds through the 85, many of it plus p, it never failed me and I used it to defend myself against a rottweiler to devastating effect. I liked the trigger on the 85 for what it was as well.
I didn't put the 605 through the same paces, maybe 150 rds? Never misfired but the trigger was atrocious I got rid of it.
Then the damn Colt Cobra remake had to come out, and I wanted a 6 shot snub for EDC, I got a Taurus 856 all steel, trigger is in the middle between that 85 and 605, so serviceable but not compared to my Smith and Wesson. It's now my edc with 1200 rds through it. It shoots to POA with 158 grain ammo and others shoot low.
