NCShadow2 Posted March 10, 2019 Share Posted March 10, 2019 Can anyone provide guidance on the fitting required to install the newer version of the Nitro Fin 2.0. Adam from Atlas told me it had to be fitted on my new Nemesis. Really don’t want to send it in for fitting, and miss next weekends match. https://www.shootersconnectionstore.com/Shooting-Sports-Innovations-Nitro-Fin-20-19112011-STISV-Slide-Lock-Thumb-Rest-P5393.aspx Link to comment Share on other sites More sharing options...
jcc7x7 Posted March 10, 2019 Share Posted March 10, 2019 (edited) Usually you just have to drill a detent in it where the pin hits it in the rear. So it doesn't engage the slide, and hold it open, while shooting Edited March 10, 2019 by jcc7x7 Link to comment Share on other sites More sharing options...
JJB05 Posted March 10, 2019 Share Posted March 10, 2019 The Nitro Fin does indeed need fitted to the gun....it does not drop right in. It also needs a detent drilled so it doesn't lock back the slide. I purchased a Phoenix Trinity thumb rest slide stop and it fit right in my Nemesis. Just needed a detent drilled.

KrymSIX Posted March 10, 2019 Share Posted March 10, 2019 @JJB05 That makes sense though. If I'm not mistaken most of Atlas' guns are built on Phoenix Trinity frames. Link to comment Share on other sites More sharing options...

Yes you are correct...however my buddy who has a new Titan and I were at the range yesterday and the PT thumb rest did not fit his Titan...so don't know if specs were different in the frames.

kk4364 Posted March 12, 2019 Share Posted March 12, 2019 Nitro fin 2.0 already has safety detent, that is part of the difference from the original. Sent from my SM-G950U using Tapatalk Link to comment Share on other sites More sharing options...
kk4364 Posted March 12, 2019 Share Posted March 12, 2019 THE BEST THUMB REST SLIDE STOP AVAILABLE. NEW FOR 2019*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 byeSent from my SM-G950U using Tapatalk Link to comment Share on other sites More sharing options...
NCShadow2 Posted March 12, 2019 Author Share Posted March 12, 2019 (edited) Interesting. I ordered the 2.0. Does this mean it will drop in or still need to be fitted? Thanks for all the replies. Edited March 12, 2019 by NCShadow2 Link to comment Share on other sites More sharing options...
kk4364 Posted March 12, 2019 Share Posted March 12, 2019 Still may need fitted, just won't need to drill detent. Also the pad is wider, and sits flatter. Sent from my SM-G950U using Tapatalk Link to comment Share on other sites More sharing options...

I ordered one a 2.0 also. Sent from my SM-N950U using Tapatalk Link to comment Share on other sites More sharing options...
NCShadow2 Posted May 12, 2019 Author Share Posted May 12, 2019 Yes. Ordered 2 and they do have to be fitted. Link to comment Share on other sites More sharing options...
CzViper Posted May 12, 2019 Share Posted May 12, 2019 What area(s) did you have to fit? Trying to narrow down my options before I start messing everything up. Sent from my SM-N950U using Tapatalk Link to comment Share on other sites More sharing options...
NCShadow2 Posted May 12, 2019 Author Share Posted May 12, 2019 Tough to get a good pic. I put black pen over where gunsmith machined. It was just a small amount where marked. Hope it helps. Link to comment Share on other sites More sharing options...
CzViper Posted May 12, 2019 Share Posted May 12, 2019 Awesome! This helps a lot and makes sense now that I'm looking at mine closer. Thank you. Especially for the pic. Sent from my SM-N950U using Tapatalk Link to comment Share on other sites More sharing options...
Goodonpaper Posted May 13, 2019 Share Posted May 13, 2019 I took a little off the inside ‘top wing’ that keeps your thumb off the slide because it was just touching the slide. Other than that it was a drop in. STI TG series frame I’ve had one practice session and one match with it and it definitely helps. Link to comment Share on other sites More sharing options...
gerritm Posted May 13, 2019 Share Posted May 13, 2019 We have installed 2 in different guns. Both were drop in no fitting. First one was an STI 3-gun 9mm the other a CZ 75 SP01. gerritm Link to comment Share on other sites More sharing options...
Postal Bob Posted May 13, 2019 Share Posted May 13, 2019 It used to be with the Nitro Fin 1.0, you'd have to drill the detent hole, and slim down the pin somewhat to fit throught the barrel link without dragging. The Ver 2 now has the detent already drilled, and much tighter tolerance of the pin. So, the only thing you have to look for is that the top of the rest, clears the bottom of the slide. And that would be a very simple procedure to fit. Link to comment Share on other sites More sharing options...
