Waited a month for Altamont Classic Panels for my 624 (N-frame square butt). I got these because I really like my 10-year old Altamont classic panels on my 19 (K-frame square butt) with a KB adapter. My favorite handgun grip period. So I had high hopes for the N-frame with a Tyler's t-grip which I have on order.
The ears do not fit well at all. These are critical for for comfort under recoil...even more important in hard recoiling N-frames.
The grip was not cut down the middle either. It's clear it is crooked and this results in a cant that effects the entire grip. It doesn't feel bad or anything, but come on. Is this high-school shop class?
Also you can see how thin these are. They are noticeably thinner than the K-frame's. What gives? You need something to hold onto with these big brutes.
Here is a Hogue so that is not perfect but a lot better.
