i have both, soft and hard. normally, i use the soft cases. they are just easier for me to manuver, and i treat my guns with care. what do i look for? obviously fit is very important. make certain it is close to the size of gun you will be transporting in it. i also look for metal zippers. one of the best (so i thought) gun case i have bought, has a plastic "self repairing"zipper. well, it may self seal next time you zip it open and shut, but it does not repair itself. i have had it open up several times while still being zipped. also, padding is very important. it is what will protect your gun if it get banged around a little. if you transport across water, a floating case would be a MUST! i can not imagine boating out to an island, loosing your gun overboard, and watching it sink to the bottom of who knows how many feet of very cold water! also pockets are very nice, even if it is not a detachable magazine gun. it will allow you to keep ammo, or a small cleaning kit, or other usefull things along with your gun. several pockets are even better. lastly, some type of material that does not absorb water is a good thing. if it absorbs water, it will hold the moisture inside, and guess what will happen to your pretty new gun sitting in the sun?!
