print settings is the right fix. but a heavier spring can work as a bandaid

Its all about balance though. In testing these printed mags, 4/13 i must have left the spring a coil or two too long, and they would bind the slide up for the first few shots until the mag was about half full. I suspect clipping a coil off those mags springs should fix it right up.

At this point im still experimenting with them.

Originally it was just blowback extraction. Extractor was added a bit over a year ago

They are essentially the same. Null is bigger improved nag. Changes from null have been incorporated into nag

Its an incredibly clever design, and when built properly, can be a lot of fun. However there is also a lot that can go wrong, especially if you aren’t an experienced builder, and when it does go wrong, it typically results in a catastrophic failure.

With that said, its not a particularly easy print, and its really for more experienced builders. It requires a lot of fine tuning to get running well, and in general isn’t very beginner friendly.

If you’re looking for a 99% printable pistol that is a bit more beginner friendly, the YH22 or SY22 are great candidates (kits available for both on my site)

You cant. I’ve taken over production of this kit from Mr. Snark, and am the only retailer licensed to sell this kit. We do not offer any shipping outside of the US, as it would be a violation of both US arms export laws, and your local laws.

This is not a super friendly build to DIY. The fire pins are machined on a lathe, then hardened. The extractor, and ejector are both laser cut, and the ejector is bent on a handmade jig. The slide weight is made in a custom mold, and would require quite a bit of work to re-create. Most of the pins and springs are readily available. If you don’t have access to a lathe, as well as a laser cutter, you should look for a more diy friendly build.

Idk about a reference model, but since the HS2000 and the XD are the same gun, the XD files may have what you need. Files include step files for full size and subcompact 9 and 40 cal

Kopsis response is spot on. Handguns are not typically the easy first build you want to start with.

I know its not as exciting as some of the other builds, but please start with some variant of the harlot. To keep it a bit more exciting, download “BLC Presents the Harlets” which is a mega pack containing all their options. The harlot is largely modular, so in many cases you can mix and match parts to build something unique.

The reasons you should start with one of these are: They force you to get familiar with 3d2a concepts like working with barrel liner, and printing parts that move against each other. They force you to calibrate your printer. They also have good documentation that covers troubleshooting of all the common issues. And finally, the stakes are lower, both from a financial standpoint (harlot kits start around $20) and from a health standpoint, that if you blow one up in your hand, its much less likely to hurt you than something larger.

Once you have not just completed building, but testing(Firing!) your harlot, move on to a more complex build. I highly recommend one of Kaewon’s builds (Baby Barrett, M4Gery, Wisp, etc) as they are generally all easy to print, assemble, and get working well, and they all look fantastic

If you’re dead set on building a handgun, the YH22 or SY22 are both good options for fully printed builds. You can think of the SY22 as a deluxe version of the YH22… the SY22 is based on the YH22, but with many enhancements made for an overall fantastic build.

If you haven’t already, check out the builds section of my site. You’ll likely find something you hadn’t seen before that you want to build!

Unsure. I believe the outer shell shape should be authentic to a real one, but outside of the pins that hold it together being the same size, I don’t have any first hand knowledge that any parts will be compatible, interchangeable, or usable from a real one

Figured builders need some fuel ya know

My advice is to print something 22. There are multiple established and beta tested fully diy 22 builds. Almost everything by Kaewon (baby barrett, m4gery, etc), or the SY22, or yh22 both went through betas and are fully printable.

But I’m probably biased. Kits available for all these builds at my username dot com

Out of the box, I don’t think so…but it uses an AR FCG, so likely possible with some extra work

Already available for pre sale, kits will ship when or just before files drop. Link at bottom of op

Yes. In the link at bottom of op

It works. You need to print it slow and hot, follow best practices

Every time I tried anything with a liner it blew up. Use the printed rifled barrel. That’s what it was designed for

Id say it leans more on the disposable side. Things like the “hammer” wear out after 75 -100 shots

Not a point, but do file the sides, reducing the tip to about 1/2 width leaving a flat front.

What spring are you using for fire pin?

No more so than any other primarily printed build. Kaewon has also iterated on the bolt over time, adding things like the SCS bolt face and breach face and extractor.

Generally speaking on a build like this, you need to make sure the extractor moves freely, make sure there are no edges of the bolt face that will catch on the upper, file the feed ramp>liner smooth, and i usually knock off any sharp edge in the 12 oclock position that might catch a round while feeding… basically make sure everything is smooth

I haven’t personally built an ez22, but I’ve done 6 complete builds of kaewon’s designs all of which were loosely based on that bolt
