The Ergo grips are pretty decent, and certainly a great value at around $26. Here's some info/images from their website: http://ergogrips.net/products/handgu...-model-92.html
I ran a set from their first production run several years ago for several years; while I replaced them with my current set of Trausch grips (virtually totally unobtainable today, unfortunately), the Ergo grips are an excellent current alternative set of 92 grips.
Some images of the Dark Earth ones on my 92D:
Here's a comparison between the various 92 grips I've run, clockwise from the upper left: Uncle Mike's/Butler Creek rubber/santoprene (Craig Spegel-designed, long out of production); Ergo Grips (hard rubber); OEM Beretta plastic, and Trausch (polymer/fiberglass).
In my experience, all are decent, but the Trausch is by far the best, as it's thinness really radically transforms the handling characteristics of a 92 for the better, and then the Ergo would be my second choice, as they possess excellent gripping characteristics without being "grabby" to clothing. They're a tad thinner than the OEM Beretta grips (and possibly to the Uncle Mike's as well), but not really significantly so.
If I was Beretta 92 grip shoppig/experimenting today, I'd probably try the Ergos first, and then the Wilson's, which are playing to pretty good reviews, but are significantly more expensive.
And my Beretta's slide is at Tooltech literally as I type, having the OEM Trijicons renewed with a orange-surround green tritium front and a black surround yellow tritium rears, and with some new experimental Check-Mate magazines en-route for testing. Hopefully, everything will come together within a week or so.
Best, Jon
