I, too, have owned 4 Webley pistols for more than 35 years...a Senior, a Premier, a Mark I, and a Tempest. Is a Premier better than a Senior or vice versa? Heck, I like all of them so much that it's really difficult to get that far down on the weeds. I will say that I have been able to reduce that 5-7 pull of the Senior trigger by extensive polishing the moving parts and using some dri-slide mixed with Beeman trigger paste on the meshing parts. It's still quite a pull.....I haven't measured it, but still probably around 3.9 to 4.4 pounds. I made a trigger shoe for mine that further reduces the pressure by spreading it across more of the finger. I don't consider either of these more than a serious plinker. All 4 of my Webleys are .177, though I have .22 barrels for 2 of them. I think you would enjoy owning and shooting either of the 2 in which you are interested.
