Looks like you may be scoping your pistol barrels? This is the rifle site so at first I couldn't tell with the scopes you mentioned.
You might get more responses over on the pistol section here.
I started shooting Contender pistols back when the only options were....two...either the Leupold 2X or the 4X..LOL!
I put the 2X on first [.35 Rem Super 14] because just having a SCOPE on a pistol was something new for me. Also put same on a Ruger Mark I 22 Auto pistol but although it was accurate it seemed to make that pistol about as cumbersome as a rifle but harder to hold on target.
I now have a Simmons 2x-6x but have not shot it enough to know much about it. I do know it's a 'on the bench only' deal when set to 6X!......I'm not used to holding the gun anywhere near as still as the 6X magnification wants!
Somehow I also have a Tasco 3X fixed now, and am scoping only one pistol, a Redhawk 44 [non 'super'] that is easy to remove or install the scope with the Ruger rings on the barrel rib. Scope on for testing loads at the range, scope off for everything else.
