I think the Altai style will go well with your 586. While I don't personally have experience with that particular Altamont grip style, I am a big fan of Altamonts and own at least 3 sets. I think they are very good quality grips and reasonably priced. As far as shipping goes, their turn around time is not bad as long as they have in stock, already produced, the grip you ordered. I seem to remember waiting around a week, maybe a day or two more, with that scenario but if they don't have them in stock and have to make them to fill your order, the wait time will be at least 2 weeks I would think.
