i just learned that grip at a class i took last weekend. when i tried it on my 229 i was amazed as it felt like i barely had control yet the rounds went exactly where i wanted. i have both the .357 sig and .40 barrel but the .357 was my hardest round to contol out of the 5 different rounds i shoot. that is until i switched to this grip:smt023
The only thing I don't care for is the hump, on the controll side of the gun. You can't rest your thumb on the safety like a 1911. I use a thumb forward grip. I take the gun, slide my left, supporting hand in, and rest my strong hand thumb on the week hand thumb. A good solid grip, which would be better without that hump.
