Romulus,
NEF stands for "New England Firearms" and they make inexpensive single-barrel break open shotguns. They're simple, but simple simply works.
As for the original question,
In California, it is illegal to just carry a gun in the car unless you are going to or from a place where you can legally posess them. Fortunately, I am usually going to work (A gun shop=AOK)home (OK) or to a friends house (OK) If I am going anywhere else, It is just a short stop on my way to one of these places.
Under these circumstances, I have a Remington 870HD 12ga Pump in the trunk. It is in a Kolpin "Marshall" soft case that has a pouch holding accesories, etc. The gun itself is intended for "road situations" of all sorts, from being stuck, broken down in the middle of nowhere, to a hotel/motel defense weapon, to a backup weapon for work. Therefore, I have added some accesories, some of which are blatently practical, while others are more personal.
I figure that if I only have one gun, and this is it, I want to cover as many bases as I can. So I installed...
1. Speedfeed Pistolgrip Stock (I like the feel of this stock bettter than standard stocks and other PG stocks...Four extra rounds is just an added bonus.)
2. Extended Magazine tube. There are some practical applications to this, like being able to load five rounds in the mag, and still have room to put in a different type of shell if deemed necessary, whether the chamber is loaded or not. Quote frankly, however, I think it looks cool.
3. Mini-Sidesaddle. The full sidesaddle won't work with the standard forend, which I prefer. The mini-sidesaddle will work, and allows four more rounds. The more the merrier.
Planned Modifications and additions:
1. Tac-Sling--Great for Hiking/movement, etc. Something to have--May not need, but again, I want as versitile a platform as possible.
2. LPA Ghost Ring sights with Tritium front post. (These seem to work very well and allow much easier shoting with slugs)
3. Surefire Forend mounted light system. This would make the gun much more versitile, but I havent decided yet whether I'd rather just cary a dedicated light, like a 6P.
There are those who feel that all the bells and whistles are needed, while others think one is foolish to spend all that money when a stock shotgun is a perfectly good weapon. In a practical sense I tend to side with the latter, but If I can afford it, and I fell it might be advantageous, I see nothing wrong wiht accessories, as long as they don't affect basic function of the gun.
