Overall it's a good design and upgrade from stock. I wanted a slightly larger magazine release but nothing huge and hanging below the trigger guard. It's fits the bill perfectly for that. My only complaint is with the triangular shape. The stock release is kind of "C" shaped or slightly hooked. I wish the serrated edge that is pressed against was less straight and more curved inward. It almost feels like there is less space for my finger to fit between the mag release and front of the trigger guard or it's just me. Not a deal breaker but a critique.

Well, I haven't tried any other options, including really using the OEM. But this works great, because you can easily push forward and up rather than getting under the lever and pushing forward and down. With this, it's like depressing a button, not toggling a lever. Works particularly well when flipping over the double cross magazines, keep the magazine release button depressed while reinserting the mag. You do have to remove your hand from the pistol grip to use this for right hand operation, which may not be the case for those trigger guard mag releases. I might file a tiny bit off the sharp corners.

Makes magazine removal much easier than issue release

Simple release that feels solid and grooves for positive opening.

Excellent, unobtrusive design that functions well.

Slightly smaller for a mag release but better priced than some of the larger releases. Adequate feedback to your fingers when you are trying to release/change out mags. Easy to install.
