-NITRO FIN THUMB REST 1.3 For Old and New imports of the Tanfoglio and CZ pistol.

Do still perform a slide off fit check in the frame before doing a full assembly.  Like all custom parts some fitting could be needed, but we did our best to hopefully eliminate that.

The Pin size is 0.196, ALL 1.3 versions have been treated with Black Nitride for durability.

Machined out of one solid piece of 17-4 stainless.  Based on the very popular Nitro Fin for the 2011 guns.  In most applications if your pin size matches....all you have to do

is slide your old slide stop out, slide this one in, and you have a thumbrest on your Limited or Open USPSA gun. This product has been tested in EAA Witness Tanfoglio LIMITED, STOCK I II III, Witness Match, CZ Shadow 2, CZ SP01, CZ75 and CZ75b firearms.  Read below!!!

PLEASE READ: Check your current slide lock for pin size.  Use caution test fitting it before test firing at the range.  The Nitro Fin by design fits close inside the slide lock relief of the frame, some gun smith work may be required.

Slide lock does not lock the slide back on last round or manually.

    Buy it!

    I bought this after one of my squad buddies recommended it. It was super easy to install and I have used it several time in the short time period I’ve had it and LOVED it. It’s definitely helped my support hand grip during matches and people have told me I’ve been shooting better. Win for me.

    Works great! Fit is excellent. I purchased two of them. I have over 3k rounds on it so far... Only thing I wish is it had more traction. It is a little slick. Some cross hatch on it would be nice

    These fit great on my A01 and shadow 2. The fit and finish are top notch, no modifications needed and they shipped out almost immediately!

    Awesome thumb rest! Best on the market. Fit and finish is amazing! No fitting required to run on my Tanfoglio Stock 3 Xtreme.

    Perfect support grip index everytime on the draw.

    Posted by Tai Lin on Jul 6th 2022

    I shoot Carry Optics and this thumb rest does an amazing job getting my support grip in perfect position everytime as well as mitigating the muzzle flip. I had improved vertical muzzle control which allowed me to pull fast and accurate splits. Highly recommend!

    Very nice product, fits and works perfect. Probably the most ergonomic and comfortable thumbrest for CZs, and definitely helps with recoil reduction.

    Truly the best.

    This is the best slide stop type thumbrest available for the Shadow 2. It allows you to consistently achieve a correct thumbs forward grip.
