I carry an M2.0 Compact 9mm daily, and have owned the Shield 9mm although not the Shield Plus. I can’t imagine switching from the Compact to the Shield for a daily carry gun because I see the smaller guns that are so popular these days as too much of a compromise for me as an EDC gun. The way I look at things, I spent a career carrying a full sized pistol as an LEO, and was forbidden by policy from carrying only a tiny little gun. There are reasons for that.
First, I demand that my carry gun be equipped with a weapon light. Next, I find that a grip that accommodates my full hand, gives me better control over the gun. The added slide length/sight radius help with accuracy, the extra weight helps tame recoil and makes fast follow up shots easier. The longer grip of the gun also helps in faster, more secure presentation from the holster for me than trying to get ahold of a nub of a grip.
I try to picture what types of scenarios might result in me needing to draw my gun, and while a small gun will work just as well as a bigger gun for a lot of them, I always picture myself in the local Wal-Mart when some looney toon decides to walk in and start shooting. I want to find my way out of that store with my family, and that might require engaging the shooter(s). How long is an aisle in your local Wal-Mart? Which gun would you want in your hands if that was the fight you had to take part in?
I carry the gun I’d want to have with me if a fight were imminent. I’d rather carry a long gun obviously, but that’s simply not an option. I do carry lesser guns when I absolutely have to, but I want a big gun when I need a gun, and I’m willing to use a good belt/holster combo, and dress around my firearm in order to do so.
Don’t get me wrong. The Shield and Shield Plus are good guns. But, as a tool for self protection, I personally prefer more gun than that.
