JPetrowski Posted January 24, 2019 Share Posted January 24, 2019 I bought a nitro fin to tryout and installed it. The pin is the same diameter but the slide will not go forward since install. Is there some sort of fit many that I need to do? Link to comment Share on other sites More sharing options...
JMike Posted January 25, 2019 Share Posted January 25, 2019 Yes, you need to get some heavy grit sand-paper and spend just little time with it. After you get it to fit, spend some time with some very fine sand-paper. Wet sanding with the fine sand paper works well. I've had to do this with 2 out of the 4 that I use.

JPetrowski Posted January 25, 2019 Author Share Posted January 25, 2019 What part am I sanding? The hook thing? Sorry. New to 1911 style pistols Link to comment Share on other sites More sharing options...
JJB05 Posted January 25, 2019 Share Posted January 25, 2019 I got one for my STI DVC and it dropped right in no problem. I did have to drill a small detent in the back so it wouldn't lock back unexpectedly. Link to comment Share on other sites More sharing options...
JPetrowski Posted January 25, 2019 Author Share Posted January 25, 2019 Pictures of what you guys are talking about would be great. I’m pretty clueless. Link to comment Share on other sites More sharing options...
Posvar Posted January 26, 2019 Share Posted January 26, 2019 I would say they are talking about the shaft that goes into the gun. It has to (1) make it through the frame hole and (2) be small enough not to catch up on the barrel link or anything else inside. With some sand paper and a little time it will be perfect. Also, the detent that was mentioned is important. Some shooters can push it up enough to make it go into slide lock while shooting freestyle and also weak hand.

Indeed...when shooting weak hand it would actuate and lock the slide back...the detent is necessary . Link to comment Share on other sites More sharing options...
Posvar Posted January 26, 2019 Share Posted January 26, 2019 Yep. It happened to me in a classifier and ended up zeroing it. Wasn’t pleased at myself for not getting it corrected sooner. I think the 2.0 has a small detent already. Link to comment Share on other sites More sharing options...

It was good idea for them to do that. Link to comment Share on other sites More sharing options...
Posvar Posted January 27, 2019 Share Posted January 27, 2019 He had quite a bit of feedback on the version 2. It’s really nice. Link to comment Share on other sites More sharing options...
JPetrowski Posted January 27, 2019 Author Share Posted January 27, 2019 The shaft goes in no problem. Once in the gun is just locked up. Seems like something else is hanging up. I hate to sand on on everything without knowing where to actually sand. Link to comment Share on other sites More sharing options...
Mike21STI Posted January 27, 2019 Share Posted January 27, 2019 Are you putting it through the link? The shaft has to pass through the link. Take a small screwdriver or allen key to get the link hole squared with the hole in the frame. Link to comment Share on other sites More sharing options...
dansedgli Posted January 27, 2019 Share Posted January 27, 2019 The pin cant be the same diameter otherwise it would work the same. Link to comment Share on other sites More sharing options...
Steve RA Posted January 27, 2019 Share Posted January 27, 2019 Sounds as though it may not have passed through the link. Link to comment Share on other sites More sharing options...
Edge40 Posted January 27, 2019 Share Posted January 27, 2019 If you have calipers check the diameter of your existing pin and match the new nitro fin to it. Doesn’t take much to hang up the slide. Link to comment Share on other sites More sharing options...
JPetrowski Posted January 27, 2019 Author Share Posted January 27, 2019 The pin passed through the link. I am %100 certain of it. It’s like once in you can’t hit the slide release to make the slide go forward. I’ll try to take a video of it later. Link to comment Share on other sites More sharing options...
Steve RA Posted January 27, 2019 Share Posted January 27, 2019 On the Nitro Fin website it mentions that there is a possibility that some of the rearmost portion may interfere with part of the frame, if the pin fits and is thru the link I'd suggest taking a close look at the fit around the frame. That might cause not being able to release the slide properly. Link to comment Share on other sites More sharing options...
joshbracken Posted January 27, 2019 Share Posted January 27, 2019 (edited) I had the same issue. I was new to 2011/1911s and after I installed the new Nitro Fin the slide would bind and not go fully forward into battery. It turns out that the barrel lockup is very sensitive to the slide lock pin diameter. Even if the diameter of the pin was off by 1 or 2 thousandths it would bind. After I sanded the diameter down to exactly the same diameter as the old slide lock pin it worked perfectly. What worked well for me was holding the NitroFin in a vice and using a thin strip of sandpaper that I could work back and forth to remove material slowly. The vice helped so I could apply some pressure with the sandpaper. Edited January 27, 2019 by joshbracken Link to comment Share on other sites More sharing options...
JPetrowski Posted January 27, 2019 Author Share Posted January 27, 2019 The pin on the nitro fin is actually slightly smaller. Link to comment Share on other sites More sharing options...
Steve RA Posted January 27, 2019 Share Posted January 27, 2019 Take the slide off and see if the Fin drags on the frame anywhere. Also does it have the depression for the pin to catch, the later models come with that and it's possible that has something to do with your problem. It's easier to see any hang-ups with the frame with the slide removed. 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 0.199 Slide lock does lock the slide back manually, but does not automatically on the last round. (Top Level Gunsmith Feature) I recommend you drill your own detent due to some firearm manufacturers not having the plunger pin in the same locations. (EX: Older Para and Caspian setups). Creating this detent will lock down the slide lock from ever being engauged on accedent, but I have no report of this happening... it's just good insurance.

JPetrowski Posted January 27, 2019 Author Share Posted January 27, 2019 Yea. Found it dragging on the frame in several places. Sanded them all down and still a no go. I’m sure there is some place I’m not seeing. Guess I’ll try to find someone local that knows more than I do (won’t be hard). I just don’t want to mess up this one and have to buy another.

CzViper Posted May 12, 2019 Share Posted May 12, 2019 Did you ever get this figured out? I have same issue and trying to narrow my options down. Sent from my SM-N950U using Tapatalk Link to comment Share on other sites More sharing options...
kk4364 Posted May 14, 2019 Share Posted May 14, 2019 I had to widen channel where the slide goes front to back. It would drag and slow the slide down. Where the slide stop goes through the frame between the outside and the contoured partSent from my SM-G950U using Tapatalk Link to comment Share on other sites More sharing options...

Postal Bob Posted May 14, 2019 Share Posted May 14, 2019 So, you had to widen the cutout notch for the slide stop in the frame? Link to comment Share on other sites More sharing options...
