*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.


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.

The Pin size is 0.1995

Slide lock does lock the slide back manually, but does not automatically on the last round. (Top Level Gunsmith Feature)

Nitro Fin 2 for DVC
I had this installed in my DVC, needed minor fitting even though it dropped right in.  It makes the grip on the pistol more secure and stable.  Should have purchased this long ago.

Nitro Fin 2.0-Perfection!
This part is nice, it's finished well and feels good to the touch. The installation was effortless, no fitting needed for my STI.  For many years my weak hand thumb was rested on the side on the side of the slide stop, pointed towards the muzzle. Hearing all the talk about the advantages of the thumb rest, and increased "control" and "target indexing", I tried one of the frame mounted products. The experience was terrible, I was going backwards fast, but I told myself I just needed to get used to it. So, after many practice sessions and matches, and moving around trying to find the sweet spot for me, I decided that it wasn't for me. This Nitro Fin 2.0 is perfect for me, and I suspect it's perfect for anyone that grips their gun with the weak thumb pointed in the direction of the target.

Kimber1911 Custom II
I had to do some filing because it didn't fit quite right but once I got it done it is a dream the way your thumb rest on it. I am very happy with this product. I bought one to use it with 2 Kimbers 9mm,45acp and Sig1911 . it works great in all of them.

Great fit
The Nitro fin 2.0 fit my SPS Pantera perfectly with no fitment issues. It is angled very nicely and really helps control the pistol during firing.
