I tried out the Eagle Secret Service grips.
Fit, symmetry, etc was simply awful, and the price was was almost 100 bucks. The grips didn't match up well, didn't follow the contour of the backstrap, and the two sides were different shades of color.
They were so bad that I just sent them back for a refund. I figured that if a company was okay with letting something like that represent their name, I really wasn't interested in getting a replacement. Anyway, after sending them back, it took multiple calls and emails over a month's time before they would refund my money through a simple paypal transfer.
Needless to say, I wouldn't recommend them.
