Thank you. I saw that thread before I posted. I guess the pinned look threw me off. So, if you say they'll work, I'll give Adam a call.

Before you get one - I have both. I just measured each of them with calipers. The older metal frame grips are only about 1/16" thicker, and 1/10" wider front to back. So they are a little bigger, but not by very much. They do, however have a thumb rest near the top and finger swells. I actually like the plastic lowers better.

Also - before you order a full lower from Adam, you might want to try RobertRTG.com - he has just the grips, and used ones are only $4 so you could see if you are going to like it or not.
