Colt and S&W grip frames are totally different and will not interchange, not even close.Don't know if the Colt and S&W pistol grip frames are the same, but did find a set of S&W uncheckered N frame stocks with the cutout for a speed loader and they fit the S&W N frame just fine. Course they conceal all of the pistol grip frame. Maybe not what you are looking for. Frank
You can get an original Tyler on Ebay. It's expensive and I'm not sure they came in large frame applications. You can get a modern Tyler T-Grip, again I don't know if the make them in large frames. There is a modern substitute for a Tyler, you can look up the website. I tried one on my Smith 1917 and the fit wasn't perfect fit.buff ------- I'd like to pick up a "T Grip". How might I go about doing so?
