Product Description
2/2/2023: Dealers and customers are chipping away at the inventory, I'll do my best to stay in stock this year. Ver 2.1 is all we will be producing.
1/4/2023: Happy New Year.. Stock is looking good.. moving forward everything we make will be the 2.1 version and YES it does drop in a Stealth Arms Platypus, but your mags will not.. you need to remove the inner Nitro Fin tab to clear the glock follower. Reports are very positive after this mod, really helps with follow up shots and overall comfort.
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)
Machined out of one solid piece of 17-4 stainless. 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. With every slide stop, do take your time and do a proper slide off mock up.
*Every opinion of the NITRO FIN 1.0 (2012 design) was used in creating the Shooting Sports Innovations Nitro Fin 2.1.
*Works with any 1911, 1911 Double Stack or 2011 variants (STI Stucatto SV Prodigy Akai PT etc). With every custom made gun a good mock up is needed and shown below in our instructional videos.
*The 1911 Stealth Arms Platypus will need the inner Nitro Fin tab removed to clear the new Glock magazine follower location.
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 0.199 with a 0.001 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.

Thumb rest
Great product. I have large hands and long thumbs. Thumb rest/ gas pedals always make shooting pistols more comfortable to me. The quality and finish on the thumb rest fantastic

Nitro Fin Thumb Rest
This is a well made durable part that fits all STI/Staccato pistols without modification. It is especially effective on .40 and .45 caliber pistols to help control muzzle flip. Worth the money to reduce time for follow up shots on target grade guns.

Nitro Fin 2.0 for MPA
Excellent product. Bought this for my MPA DS9. Pin size is perfect. The bottom edge of the slide lock needed some minor filing to seat into the MPA frame. Note: it clears in a Ghost Hydra P holster perfectly.

Overall sitting at your fan was OK
I like the nitro fan however I think it should’ve been at least a quarter of an inch longer and for some reason I have to keep pushing it into the slide to keep it up against the slide. I don’t know if it’s my detent that’s not working correctly or what
