Nitro Fin STI and SV 2011 Slide Lock Thumb Rest


These thumb rests are gun parts and cannot be shipped outside the U.S.

The product from Shooting Sports Innovations that combines a thumb rest with the slide stop. Fits STI/SV 2011 guns. Machined out of a solid piece of 17-4 stainless steel. Available in black nitride or machine polished finish. In most cases, all you have to do is replace your current slide stop with the Nitro Fin and you're done. The pin side of the product is machined somewhat flat and makes for a nice appearance on the ejection port side of the gun. No drilling and tapping required as with other gas pedals and thumb rests. Makes the gun much easier to take down to clean because it gives you a larger area to grab and pull the slide release to remove it. Price is $125 which is less than the cost of a quality slide stop, thumb rest, drill, tap, and installation.

This is the new 2.0 model which includes updates to the original offering:

-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 tolerance 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.

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)
