Ron Graham's web site is found at:
http://www.grahamholsters.com/DDGator is with K-D.
You have seen JR's.
I have no financial, business, or family relationship with any holster maker, except that I have appointed myself as Ron Graham's number one cheerleader. I can be quite obnoxious about my very vocal support of Ron's business. I love his products. Currently I own 38 holsters and other stuff made by him. I have two orders now outstanding that should bring me to close to 50 of his products.
Ron has several front pocket holster designs. He also has the Maverick, that is a rear pocket holster with a removable anti-print panel that allows it to be carried in the front pocket. The Maverick is becoming a very big seller.
His front pocket holsters include the Twin Peaks, my favorite, the Night Owl, Cookie, and Super Cookie.
As to the Rohrbaugh, he has several new designs ready, a couple of them he has posted photo's of on his web site. He is trying to time his new designs to the publication date of the AMerican Handgunner article of the Rohrbaugh, since some of his exotic holsters were provided with the gun for the article.
At trade shows, North American Arms, Springfield Armory, and Rohrbaugh have all used Ron's products as part of their presentation.
Rohrbaugh has made some special guns for use in a movie to be released. Ron made the leather (I assume with exotic leather.)
If you like exotic leather holsters, Ron makes great holsters in about 5 different exotic leathers. I won several sharkskin holsters, as well as a holster made in sting ray skin, and ostrich. Although elephant is becoming very popular. Price wise, Ron's products, especially his exotics, are quite reasonable.
