Any of you swap out the Sub 2000 gen 2 factory sights with the M*CARBO rear tactical folding sight with the larger aperture, and the Red Lion flip up front sight? I’m putting on a Holosun HS510C, but don’t care for going the co-witness route, so I’m looking at all the fold down options

I run those irons. I have that optic on my 9mm AR. I run a Holosun 507C pistol circle dot on the Sub.
So … question for you - not related. Since S&W finally offered 10mm, do you think they’ll offer a FPC in 10? Yes, spooky that I know you share my love for 10mm. I’m going to grab a 9mm FPC soon and hope for a 10.

The M*Carbo rear sight is a good option but you also can drill out the aperture of the OEM sight and trim the “ears” to allow it to fold. See image below. If you remove just the perfect amount, the OEM rear sight will still auto-deploy when you unfold the firearm but easily fold down. The Red Lion is the best option for the front sight.

I did the Mcarbo aluminum, folding rear sight. And just recently received the Redlion, front folding sight, but have not installed it yet. But I also have a Red Dot Optic, which I mounted to a riser, off the Mcarbo flip mount. I like the optical and shooting position way better than the peep sight! I no longer have to jam my face on to the bolt tube, much more comfortable.
Iron sights are a backup necessity, especially if you’re worried about using your rifle as a defensive weapon.
Having said the above, I wish I would’ve drilled out the OEM Kel Tec sight, but, I’m extremely happy with the Mcarbo peep sight as an upgrade, but I could have waited to spend the money on that upgrade!

Thanks, what aprx is the exact amount to trim? Is it safe to say the M*Carbo rear and the Red Lion front will work well together
Thanks for your help

Less is more. You only need to remove enough to clear the flange that stops it from folding down and that is less than it appears. Take a little then test and repeat as needed. Worst case it will no longer auto-deploy but neither will the Red Lion front sight. If it truly matters, try again as a replacement from KelTec is cheap. The M*Carbo sight is a bit taller but my OEM one aligns fine with the Red Lion front sight.

Thanks man, M*Carbo just told me they have not done any testing with their rear sight and the Red Lion front as to compatibility and I’m on my own, seems odd they haven’t looked into that

How are you removing the small amount of material? A file, dremel tool, or something else? Thanks again for your help

We have. You’re good to go. Apologies for my lack of clarity. I had my rear cut to allow folding before I went MCARBO Peep before I went Red Lion.
Folks have had trouble with the MCARBO open which is solved by longer front post. The peep is close enough that the sight’s elevation adjustment is plenty.
Material removal was side cutters for me. I did it with the sight installed and did achieve autodeploy but capability to fold it out of the way when desired.

I used a razor knife but snips or a dremel should also work. Remember less is more.

You guys are awesome, just sayen. So I’ll very slowly nibble off some material until the rears able to fold down, and slightly enlarge the aperture hole. I’m assuming my factory front will work with the modified rear until I get the Red Lion front, correct? As for removing the factory front sight and installing the folding RL, is this pretty straight forward? I’m not seeing much for videos on this process

I had no issues. Just be careful not to mar the barrel.
I think you will like the larger aperture. You may want to start small since you can always enlarge the hole.

sight will work regardless of front.
Install is very straight forward. Installing RL front is MUCH easier than reinstalling factory. Bonus is that no rocksett, loctite or other is required to stabilize RL front.
Biggest trick is factory front removal. Vise with barrel jaws makes it stress free. Remember that the barrel is set in a plastic pivot. So, if front sight requires too much lefty loosey, stabilize towel wrapped barrel with offset pliers until sight is turning for you.

Reminds me of the time about 7 years into my marriage when I told the wife I was thinking about getting a little strange. She told me if I was better hung, I could get plenty of strange at home.

Having my Redlion sight installed the 15th at Kel Tec, I have the Mcarbo peep, I’ll let you know how it goes!

I thought only Gen1 had that issue and Gen2 was just threaded on?

Absolutely, let us know

The threading IS the issue. G2 simply unscrews lefty loosey but it can be hard to get the lefty loosey started because some form of adhesive was required to keep it from unscrewing when bumped.

Thanks, so other than getting it loose, is it a pretty basic / easy upgrade on the gen 2? I guess the question is, how do you free it up without damaging anything
Thanks
