These are checkered Pau Ferro wood. Fit is fine and they do not move when in place. Neither do they protrude into the magazine well and bind against the magazine.

Here's the other side. Though I use only a single-side thumb safety, these will work with the extended ambidextrous thumb safety which comes standard on the current crop of Hi Power pistols.
To me, the feel is as good as any other Hi Power stocks I've tried, though I admit that is completely subjective and others might or might not agree. Thickness is similar to the Spegel and these grips offered good purchase while firing.
If memory serves, I had to wait a few weeks for these.
If a Hi Power shooter is perusing the Internet for a set of new Hi Power grips, Mr. Hogue's products might be worth a hard look.
Best.
