Go to www.t-grips.com and the Tyler t-grip grip adapter has their webpage and catalogue. I have been buying from them almost all my life and the ones I got a couple of months ago were the same quality as the ones I bought 30 years ago. Don't know who runs the business right now as Mr Tyler has passed on. They are a part time production so delivery may not be super quick but they are the best made. I have them on almost all my revolvers especially the round butt ones.
