I want to buy a set of Truglo® Pro Series Magnum Gobble-Dot. They come in different width:

Available:[*]<1/4" Width - Fits most Remington, Ithaca and Browning A5 and other ribs measuring 7mm.[*]3/8" Width - Fits most Mossberg and Winchester models. Also fits most 10-ga. models.[*]6mm Width - Fits most Browning Gold Hunter Series and Beretta Field Grade models.[*]5/16" Width - Fits most Benelli Super Black Eagle, Benelli Nova, Browning BPS and Browning A-5 models and Ruger Red Label. (To ensure proper fit, we recommend measurin
My gun is a Remington 1100 G3, with a rib width of 7.4 mm. So it looks like the 1/4" (6.35 mm) width is not going to work. My next best choice would be the 5/16" (7.93 mm).

Do you have any experience with this product and how they fit?

Thanks.
