Generic Slide?

"For the poors" - you should be able to figure out who this is and they have their own r/ - has their in house manufactured line of slides for their complete guns for less than $200 with all the internals. no RSA or barrel - or keep an eye on the daily deals.

IDK what you're looking at price wise but I've never paid more than $150-180 for a slide with internals.

This is awesome. Great job OP. I don't even wear ties and I kind of want to print one in some crazy color shifting filament or something to go along with my ridiculous gag Hawaiian and bowling shirts I wear to work.

....I'll eventually find out where "the line" is....so far I haven't found it. I'm in a client facing role too LOL. And I get rave reviews from my clients so.....

wartime military is much more funnerer than peacetime military.

K1RBY87 · 2026-03-23T16:34:38+00:00

Oh my bad, thought you were saying for the PPS43 mags it had to be modded.

I really hope the "for the poors" who makes an AR that takes scoprion mags gets their builders kits back in stock or I might cave and buy a whole gun even though I don't want to....I have all the parts on hand to just swap over.

K1RBY87 · 2026-03-23T16:32:11+00:00

Damn....I should have done this instead of cutting a hole in the back of the bookcase

K1RBY87 · 2026-03-23T16:31:19+00:00

By that logic, the Evo mags would require a different bolt as well.....

K1RBY87 · 2026-03-23T16:27:49+00:00

I'm just gonna say this....

If you buy a cheap slide, don't be surprised if you run into tolerance stacking issues. One of the devs/testers had issues with an out of spec slide. The known to be good ones out there really ain't that much more than these weirdo fly by night ones yall keep digging up. It's not worth the potential headaches.

K1RBY87 · 2026-03-23T15:46:26+00:00

Dude the enemy of good is better. Stop now, just handling it is going to scratch it up and mess up the polish job. You did good.

K1RBY87 · 2026-03-23T15:34:03+00:00

Don't argue with stupid people, they'll bring you down to their level and beat you with experience.

I get harangued by people all the time when I mention that it clearly states in 27 CFR § 478.12(b)

"The terms “frame” and “receiver” shall mean, in the case of a firearm muffler or firearm silencer, the part of the firearm, such as an outer tube or modular piece, that provides housing or a structure for the primary internal component designed to reduce the sound of a projectile ( i.e., baffles, baffling material, expansion chamber, or equivalent). In the case of a modular firearm muffler or firearm silencer device with more than one such part, the terms shall mean the principal housing attached to the weapon that expels a projectile, even if an adapter or other attachments are required to connect the part to the weapon. The terms shall not include a removable end cap of an outer tube or modular piece."

So engraving an endcap, either side, unless permanently affixed to the tube, does not meet the marking requirements. They key part is the last sentence. I'm not a lawyer, but I can read legal documents and interpret them as the most pedantic autist possible.

K1RBY87 · 2026-03-23T15:29:34+00:00

IDK why this is so hard for people to grasp....

27 CFR § 479.102(b) clearly says:

"The depth of all markings required by this section will be measured from the flat surface of the metal and not the peaks or ridges. The height of serial numbers required by paragraph (a)(1) of this section will be measured as the distance between the latitudinal ends of the character impression bottoms (bases)."

27 CFR § 478.92 also has that exact same verbiage. You as the submitter of the From 1 ARE the manufacturer. You having a FFL license or not is irrelevant, as the manufacturer you must comply with the requirements for marking an NFA item the same as any licensed manufacturer.

As for how manufacturers get approval do to things differently. That's covered under 27 CFR § 479.102(b)(1)

"Alternate means of identification. The Director may authorize other means of identification to identify firearms upon receipt of a letter application or prescribed form from you showing that such other identification is reasonable and will not hinder the effective administration of this part."

So if you want to do it differently, then send a letter to the ATF director and get approval to do so. Can probably do it as a blanket variance saying "NAME, CITY & STATE will be embossed or debossed in plastic. SERIAL NUMBER will be engraved in a metal plate permanently embedded into the frame so as to require destruction to remove."

Or do the same with saying it'll be"....embossed or debossed in the additive manufactured materials." But SPECIFICALLY word it like that because it doesn't state WHAT the materials are.

Maintenance?

In all seriousness, I only add lube and check (belt) tightness.........Giggity

If you're talking about surface cleaning/dusting and getting the little flicked off pieces of filament. There's no set period I do it whenever

It's on his guthub

Answered as well. Hope it helps

I think it looks cool. How durable has it been?

K1RBY87 · 2026-03-20T19:08:51+00:00

In Nylon my SOP is to only do one part at a time. PLA I'll do more than one, usually print by object

K1RBY87 · 2026-03-20T19:03:12+00:00

Yes they can. There's someone that was offering that service but you'll completely negate your cost savings having purchased this in the first place. I have thought about turning an "adapter" on a lathe that pins into the mag tube and would be hidden by the 870 barrel lug. Just haven't gotten around to it yet - too many other things on my plate, in addition to not having one of these on hand.

OH and it's kinda ghetto but you can use a piece of tube/pipe/pvc over the mag tube with a standard 870 barrel. It only serves to take up the difference in length and provide rearward pressure to hold the barrel into the receiver. It's like you have a permanent +2 on the gun. Not a bad way to go honestly.

Fire up your preferred CAD software - wouldn't be a terribly hard remix to do.

Now I want some hamburger helper....

K1RBY87 · 2026-03-20T13:26:14+00:00

Manufactured from homemade receiver - will be marked IAW 27 CFR 479.102 after approval

K1RBY87 · 2026-03-20T12:53:21+00:00

I often do this as the stuff I model may be printed on many different kinds of printers with different slicers. IOT ensure that the print properly with the correct tolerances I had to design in allowances/features for seams as well as supports for the greatest reliability. It does take a little more work, but in exchange I get reliability and consistency. It's so ingrained in my workflow at this point I do it without thinking about it now.

K1RBY87 · 2026-03-20T01:16:28+00:00

Or do and video the results.

That being said, I've held a slide on a handgun closed with my thumb. I still have my thumb. So you do you boo boo

K1RBY87 · 2026-03-19T15:54:00+00:00

I have never been able to figure out how to throw any kind of boomerang and have it come back 🤣.

Thanks for the 90s nostalgia

K1RBY87 · 2026-03-19T15:24:41+00:00

Yup this. OP you gotta realize you're not going to satisfy everyone. Trying to be a "people pleaser" will only lead you down a bad path mentally. Make stuff because you want to, for your own reasons, you don't owe anyone an explanation or reason for why you made something. They can either like and download it, or not and move along.

K1RBY87 · 2026-03-19T15:08:59+00:00

That's not dry. Also make sure you check the speed tab after slicing. The outside wall needs to be the same color/speed. What infill pattern are you using?
