-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.

    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.

    IDPA Legal

    Posted by Eric on Apr 18th 2022

    This is the best thumbrest for the Shadow 2. I held off buying this one because it won't lock the slide back. I used another brand with moderate success. But now, IDPA rules have changed allowing the slide stop to be disabled and no longer requiring slide lock reloads. Plus, the Nitro Fin fits the IDPA Carry Optics box. This is a true game changer and I'm so glad I finally have a Nitro Fin on my Shadow 2 to get the most out of this competitive advantage.

    Great product and fit like a glove in the Sar K12 Sport as well as the CZ Shadow Orange 2. Required no fitting or modification at all. Great company that is quick to answer any questions you have. I highly recommend them and their products!

    AMAZING thumb rest/gas pedal

    Posted by Derek Cooley on Apr 14th 2021

    I currently have 2 Nitro Fin thumbrests, and will be ordering another soon. For a comp pistol, or a quality range toy; these are AWESOME! Don't let the price deter you, they're worth their weight in Rhodium. Solid 1-piece stainless construction, as well as good machining makes this one of my favorite add-ons. Thanks again, SSI!

    Nitrofin Slide Lock Thumb Rest- Tanfoglio

    Posted by Thomas P Hughes on Mar 15th 2021

    The thumb rest changed the ergonomics of gripping my P01 significantly, in particular allowing for increased resistance to muzzle rise, and for a greater degree of frame contact by the support hand. The best part of the company is the degree of professionalism and engagement apparent after you talk with Nathan for two minutes.

    Nitrofin for CZ Shadow 2

    Posted by Wood on Mar 9th 2021

    Absolutely one of the best upgrades I have done. I had to sand the very tip of the pin, it was a little tight. Now it slides in and out without a problem.

    Already a customer for my 2011. Wanted one for my CZ SP-01. Fit perfect without any smithing needed. Runs fantastic and helps with control;/accuracy.
