It's sturdy and has some level of adjustment.
It would be interesting if it could be inverted and be used in a lower position and be more suited for smaller hands.

You get a well construted and very important piece with this Thumb Rest. It's well worth the money.

Another fantastic product from Double Alpha.
Installed in minutes.
I simply slipped a M4 nut over the end of the bolt. Cut the excess off the bolt and removed the nut. No messing around and a clean cut bolt.
The perfect finishing touch to my 1911.
Thanks Double Alpha

Nice quality.
Could make the mounting hole pattern different for more option. I have small hands, so I drilled up the two first wholes a little so that I could get it as far back as possible on my Tanfo Lim.Custom GK
But you then need to remove the slidestop with a Henning og EGW slidestop instead!
I also cut the adjusting screw a litte on the back side for allowing the full use of the thum paddel.

The screws, when screwed to the end, interfere with the action on my pistol - Tanfoglio LC II. You have to file the crews in order for the pistol to function.

Also, I have small hands, and the thumb rest is a little too far for my reach.

This thumbrest is very good, but a little bit too far forward! The screws that came with it are very handy.

Saw it on my buddys gun and had to have one! Fully adjustable, will prob fit any size hand (thumb). Shipping was faaaast to Canada only 9 Days
