My 442 currently wears ERGO Delta grips. They look strange and it takes a few seconds to accustom oneself to the feel. 5 yard accuracy is as before -- never great with a 10 lb. trigger pull, but adequate. And these grips do eliminate the trigger guard smack on the middle finger's second knuckle, a big problem for me. After 50 rounds or so the webbing of the hand does get a little sore from the hard backside of the grip. It is still a work in progress.....
