T-grips are great. They do fill out the hand and they preserve the original look and let you sport correct grips.
That said,
TYLER T-grips, as a company, SUCKS!Wait times of six to nine months. Seriously. Send off a check and forget about it. If you're lucky, your order might arrive within a year. Or not . . .
Search the web, especially the Smith & Wesson forum, you'll see. There's a reason why Tyler T-grips bring $60-$75 on ebay, when they're listed for less than $30 on the manufacturer's website.
All that said, there's an perfectly good alternative. BK Grips are plastic, but they work just fine and do the job. Once they're on the gun, you won't know the difference. Plus, they don't come in silver. But, the guy actually ships his product quickly with no drama.
Skip Tyler unless you can find them used. Go with BK instead:
