HK P30 / SFP9 / VP9 3d printable magazine (uses G17 spring)[V3.2]

cults3d

Version 3 of my 3d printable HK P30/SFP9/VP9 magazine, now it's a package that contains: -15 round magazine -10 round magazine -30 round magazine (proof of concept) -loading tool -version 2 As i said previously, i only own P30 so if there are any fit issues with SFP9/VP9, let me know. 15 round magazine is the standard version and other versions are based off it. Compared to V2, it holds one round less but (among other improvements) provides better feed angle, making the whole loading process smoother. It uses a standard Glock 17 magazine spring. I dropped the option to use HK 17-round spring - it provides no benefits as capacity is now limited by follower and main body design, not the spring as in V2. You can probably still use it, I just don't see the point. There is an indentation on the back you can drill out with 2 mm or smaller bit for indication when magazine is fully loaded. 10 rounder is modified as shown in last picture for people living in countries where magazine capacity is limited by law. It has a fin that prevents follower from going any lower than 10 rounds. Main body and floorplate are modified to only accept the lockplate that reduces the capacity. Turning it back to 15 either requires using a tool to permanently modify it OR printing new parts. It's up to you to know whether this is is enough to make the magazine legal where you live. I honestly don't think you can make a 3d printable design more "conversion proof" than this. It'll be always easier to print a new mag than fiddle around with saws or files to modify the 10-rounder. It also uses G17 magazine spring. There is an indentation on the back you can drill out with 2 mm or smaller bit for indication when magazine is fully loaded. The 30 rounder should be considered a proof of concept more than anything else. I don't have any 33-round Glock springs, so i made a spring spacer that allows using two G17 springs instead. It seems to work well when dry cycling. I will not do ANY extensive live fire testing any time soon. Maybe once the availability (and hopefully prices) of 9mm are back to normal i'll make a stock to turn the pistol into a small PDW (maybe even style it after MP7). Then 30-round mag would make sense, so testing it would as well. After printing use sharp blade to remove any remains of custom supports. They are kinda necessary to stabilize the print, but are easily removable and require little clean up afterwards. All magazines assemble just like the factory magazine, just make sure the spring is in proper orientation and you will be fine. The loading tool is recommended to load the magazine. You can load it by hand, but loading tool is better. If you don't have one, you can print provided design. Either way tap the magazine a few times on something hard after loading. Potential issues: 1. Initially the magazine might not drop freely. It is generally caused by the friction between follower and magazine caused by layer lines. The issue should go away once contact surfaces smooth out. For me it generally happens after loading the magazine to full capacity and unloading it 3-4 times. I would assume this would depend on material You printed magazine out of, so your mileage may vary. I include the V2 because some people already bought it.
