What is a good source for lower profile sling swivels for a side by side shotgun. I have had sling swivels added to two shotguns by local gunsmiths lately and they both insist that the ONLY ones they can get are from Brownells and they are detachable and long stemmed and I think they look "unsightly", "ugly", "nasty" on a beautiful side by side! I am looking for BOTH front and rear swivels. Must be low profile like the older swivels you see on older, finer guns that have swivels, like on some Merkels I have handled. Any help here would be greatly appreciated!
