Installs easily, great quality with fast delivery from Tandemkross.

It didn't fit out of the package. Returned it and they sent a fitted one. That didn't work either but was closer, so a little filing and I had it working. Customer service was very helpful. It wouldn't clear the thumb-rest on my Competition model either, so I had to make a spacer. Ended up using the paddle facing forward. I hit it with my middle finger of right hand. I like it.

Highly recommend, lager finger area, good choice install either round or longer surface. Followed online install video. Chose larger round button very good surface for positive push area.

This was a well made extended mag release for my MK IV. Since I have turned this into a Steel Challenge, I have aftermarket grips. The TK extended mag release is a great addition to this pistol along with all the other TK addition. TK has great products and fast shipping. Videos are great help to installation.

I have had problems with releasing the magazine without changing my firing grip. After installing the extended magazine release button I can now eject the magazine while the pistol is still down range, on target. I do not have to see the pistol to do a magazine change. Great product!

It makes it easier to find and press the magazine release. Great! Also has a couple of options for configuration to suit your preferences.

Yeah this extended mag release does exactly what I was hoping it would do. I installed it on my MarkIV Target and now it is very easy to drop a mag out without contorting my hand. The ooooonly thing wrong with it is that it works a little too well -- every time I lay the gun down on its left side it spits the mag out. If I put the gun in its case with a mag in it, it releases the mag. The problem there is if I forget (like always) when I take the gun out of its case the mag falls out on the floor. I'm inclined to live with that because of how easy it is to release mags.

Excellent [TK] product. It adds to the enjoyment of my Ruger Mark III Hunter in a big way. I used the round button option and it works great. Easy to install. Highly recommended.

Because of small hands (limited thumb reach) and G10 grips with no release bevel, I knew an extended release was needed. I tried both styles and settled for the paddle. Two benefits: Thumb can now activate mag release without changing grip; Paddle creates a thumb-placement guide for consistent hold. The caveat was that the mage are stiff going in (slightly). The cure was taking each mag and doing about 10 R&R's until they were mated to the new tolerances. The mags need a little 'pop'as they go in, but retention is perfect, release is correct, and no failures of any kind since install.
