If your T-grip is for an "early" J-frame or "modified I-frame, pre-1957, it will fit. If cut for a modern J-frame it will "work" but won't fit perfectly. But fear not, Tyler Manufacturing is still in business http://www.t-grips.com/ FOR ORDERING, you may send in a personal check, postal money order, cashier's check, or bank money order to:

Not "in stock" for immediate shipment, but worth the wait, they can make to order for you a T-grip to fit the older S&W I-frame. Delivery is about 30 days. They are also the only game in town to properly fit the pre-1940 Colt Police Positives, Pocket Positive and New Service, here are a few more of mine, excuse the thread drift, these are .38 S&W/Colt New Polices:
