-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.

    Nitro super fin

    The fin is great. It takes some getting used to but I think it will make me faster. It’s very well built and solid.

    Very nice looking part that installed without any modifications. It looks like it came on the gun, CZ75 SP01, from the manufacturer. Very happy with the position for my support thumb.

    Obviously a 5 star review. I knew what I was getting into and as advertised, awesome product. Like everyone else, I wish this locked the slide back but I also live in the real world. Thanks SSI for a great product. My review is from June of 2023. This fin has stood the test of time.

    Nitro Fin 1.3 for SP01

    IMO a proper grip starts with a extra wide safety and a Nitrofin to help lock your grip into place.

    Buy it!

    Posted by Amber C on Aug 24th 2022

    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!!

    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
