monkeygrips IMO the best 1911 grips around. really friendly guy and more then willing to do custom grips if you dont see one that tickles your fancy. the grips he did for me are called XS shredders, not pictured on his site but he did them for no extra charge.
I believe that the best place to purchase new grips may indeed amount to the style of grip you are looking for, presentation, tactical, my personal favorite novelty etc... I guess if you have smiley faces on your grips you cant go wrong! LOL, or flaming ace of spades / 100 dollar bills! Get some bling for your bang. Kidding. I have purchased a few sets of grips over the years for my Springers and was blown away by the vast selection of styles. Good luck!
Get different color grips to match different outfits! OK maybe I have gone overboard? My wife will let me know.
