Fin,
It's a magazine, not a clip....You know that....LOL

I like the Mepro 21 reflex as it allows you to keep both eyes open during fire...cause as you know, when you are relaxed at the range, closing that one eye while you assasinate beer cans and milk cartons filled with water, is a little different than swiss cheesing the drivers' side door of a urban "starship" with 22's on it...Generally your adrenaline is pumping and chances are you are going to have both eyes open, VERY OPEN at the time...I would consider some type of small light with a contact switch that is pressure sensative for low light conditions but is not constant to make sure you are not a lit target...If it were a primary in home weapon, which I wouldn't recommend due to penetration of sheet rock, brick and anything else the round contacts, I might recommend a shorter barrel to slice the pie...But I'm sure you have a barely legal scatter gun for that anyway...I know I do...Sweet heater and i know you are gonna put a tach sling on that thing as well, right? I think you are on the right track...lightweight, no bells or whistles...essential gear to put lead on target fast and no prop needed to keep someone at gunpoint for 5 plus minutes....until witnesses arrive...
