12/4/2023: Fedex lost a batch of 2.0's coming back from Black Nitride. It is now found and on the way home this week. Over the weekend we sent a batch of 2.1's for Black Nitride, hope to have them available in two weeks.
THE BEST THUMB REST SLIDE STOP AVAILABLE.
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 lock the slide back manually, but does not automatically on the last round. (Top Level Gunsmith Feature)
*Every opinion of the NITRO FIN 1.0 (2012 design) was used in creating the Shooting Sports Innovations Nitro Fin 2.0.
Listed below are the main key changes.
-THUMB REST PAD REDESIGN: It's 0.150 WIDER, This came from the USPSA Open shooters mainly.. They needed it wider to compensate for the scope mount. We understand everyone has a different thumb and it's curved, so a flatter pad angle increased the surface area. We undercut and reduced the rear section of the pad to eliminate any discomfort shooting weak handed.
-PIN QUALITY OVERHAUL: We changed our methods of machining the pins. This resulted in a no taper, tighter toleranced pin. Now 0.1995 with a 0.00025 tolerance. Longer pin to aid in removal and for wider frames.
-SLIDE TAB CALIBRATION: We increased the height and changed it's shape to not contact Grams followers. Also put a nice radius on that tab to aid in installation.
-LOWER THUMB SHIELD: Some reported hitting the shield when racking the slide. We lowered it to the min height.
-REAR DETENT BLOCK: We averaged all the frames we could measure and made a recessed block to capture your slide stop plunger. Ever experienced the slide locking back while shooting weak hand? Kiss that problem good bye.
-Availble in machined polished or black nitride coating.

It's perfect out of the box for my staccato xc and C2. Shot over 300 rounds and zero issue. Great products and highly recommended ?

love it so much i purchased another one. fitment was perfect, easy to install.
I ordered one for my staccato XC . It fit perfectly with no fitting necessary .
The Nitro fin is a game changer, awesome product !
I install on my MPA DS9 hybrid for LO. Feels great and perfect for repeating indexing. Pin size was very close to stock pin. Had to machine slide catch. If not familiar take to gun smith. There was good info provided for fitting. Would definitely buy again.
Best thumb rest ever
I used to make a similar thing years ago out of a slide stop & a thumb safety, but no longer have access to a micro-welder. So I bought one of these. It's kind of a shame I did so much machine & file work as it was beautiful, more like jewelry. I narrowed the paddle & took off the thumb guard. As is, it's okay on an open gun, but I put this on a limited gun. It fit in the gun without issue & functions correctly. While it doesn't lock back, it can manually hold open the slide, which is needed for clearing malfs, showing safe, etc. I doubt I'll ever build another 1911 for USPSA, but if I do, it'll have one of these on it.
