-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 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.
