Christmas Forever presents - PX4 Magazine release

This is the entire polymer assembly to get a working mag release.
you will need one print each of:

• a mandrel
• a female magazine release housing
• a male magazine release

hardware
- OEM PX4 magazine release spring or a 0.3" OD, 0.234" ID, 4 coil, 0.4" length, 22GA wire compression spring.

file choice

try the normal female magazine release and if that doesnt feel the way you want it to try the looser one. On .45 I havent found a good balance that will drop free and also not
eject the magazine on slide movement so the mags will stick a bit but they'll cycle.

instructions

put the male piece into the female housing then lock it in with the mandrel. the male piece is a collet that will expand when the mandrel is placed in it to keep it in place.
the printed version has no taper unlike the OEM part. its not necessary with the friction from the layered print.

0.4mm nozzle only, 0.6mm wont work. It's a small part. 0.2mm layer is fine.

You will have to print the male file parallel to your X axis at the least. Its the only part you can't print on one of its end upwards. However, I would recommend printing all 3 files
laying down in this fashion. The collet arms will break off immediately if you don't print the male laying down.
Refer to the images near the readme for suggested orientation

disassembly

the OEM assembly is a PITA to dissassemble but the christmas forever version if you print two mandrels you can use one as a dissasembly tool. just push the mandrel into the male
side.

Male Magazine release differences

There are a couple magazine releases to choose from and the difference between them is about .100" with exception of the MONDO size which is .500". If you are printing this for the
Deterrence Dispensed PPX4 92 mag version I would recommend the extended at least with how it extends the trigger guard.

notes

• this was made for and tested with the Deterrence Dispensed PPX4 92 magazine model. Specifically a .40 cal but my 9mm magazines also worked (avoid printing that model the trigger guard makes it unusable)
• should work with an OEM PX4 frame
• this was tested with a 0.4mm nozzle with 0.4mm layer lines
• the magazine lug was tight before but was reworked. It works well for 9/40 but needs work on 45.
