yes, i received one a year and a half ago made by Milt Sparks from their Summer Special (S/S) line of IWB holsters.
they say they don't make too many IWB holsters for the SAA, never more than a couple a year, so they seem to be pretty rare items.
mine was build for a 4.75" Colt in Natural Tan with 1.75" belt loops for right-hand carry. price was $92 and wait time was over 8 months. i got it to fit the longest SAA barrel i have, but it works perfectly with my 3.5" USFA Storekeeper and 3.75" Ruger Montado (and doesn't look or feel silly, like it does when wearing a long exposed/visible holster with a short barreled gun).
i've been buying milt's holsters for almost 40 years. having tired many many brands, i think they are the best there is. leather, quality, design are all top-notch.
i've worn it twice when i went to the city, but where i live concealment isn't an issue so it sits unused. i didn't find wearing it any different than any other Summer Special i've owned that was built for a large handgun (of course smaller-thinner guns are a bit easier to pack in the waistband).
if you want to order one, they only take new orders twice a year. next date for new orders is May 1st 2010. i suggest starting to call very early in the day because i got a busy signal for over 4 hours before i got through. you can read about the rules for ordering on the home page.
http://www.miltsparks.com/from the Summer Special page:
"Designed by the late Bruce Nelson, the Summer Special has become the classic IWB holster by which all others are judged. With permission, Milt began producing the Summer Special, helping to meet the demand Bruce was unable to fulfill due to his then involvement in law enforcement. Milt initially improved on the design by adding sight rails, and then again later with the addition of a second belt loop The S/S features a metal stiffener in the top band which allows for effortless one handed re-holstering. Belt loops are secured with one way directional snaps. The rough out leather grips the clothing for secure positioning, and the smooth interior is easier on your guns finish.
The Summer Special comes standard with two belt loops, except for small revolvers and some small autos which come with one loop. Please specify your belt width so we can properly fit the belt loop."hope that helps.
