Just dropping a line here in case anyone was considering trying this out on an actual glock. Heat issues aside, in the USA the ATF considers a second vertical grip to reclassify the pistol as an AOW (any other weapon) and requires NFA registration and tax stamp. You can do it, but you have to get your Form 1 approved first. See the link below for more information.


Guten Tag würde das modell auch an einer Glock 17 generation 4 Passen (Ich meine die Airsoft version)?

Hi. I made a small modification of your design which you could use to simplify the mag release mechanism. Instead of having a hole in mag release slide I made it a long opening this allows to anchor the metal pin and make it static guide rod rather than moving element. I made this in already printed element but maybe you could made it much nicer in model itself.
Second modification I am trying to make is to anchor the spring as it likes to pop out. To do this I was thinking about two cylinder shaped holes sunk in both slide and case to better keep spring in place. And in worst case scenario it would allow for a drop of hot glue to be added without compromising spring working area . But it proves dit difficult on printed elements. Maybe you will consider this for next model update?
Thank you for your work and sharing it!

My Thinkercad skills are quite basic but if you would share the thinkercad links I could modify your design.

ill check later today if theres anything i can share from tinkercad, i think i "glued" all part already, need to check (exported then re-imported).

i just sent you the link via private message

I love this design. As far as I know this in the only one here with active mag retention! One question would you consider adding top rail for rds as well? Ideal would be low profile rail placing RDS over the rear sight post without compromising side rails. Also frong grip could benefit from some patterns on side to improve handling. Otherwise it is great desing and I will defitely try it. Thank you for sharing.

Hello Andrew, im not really into airsoft tbh, i did that just for the fun. ill check in a few days to add some rail on top. need to find exemple of compatible rails for the G18 + sizes etc

Hey m8! Any way at all you could mod me a file for the Springfield XDs - 4" 9mm? I would happily leave you a tip!!

Hello Acets, unfortunatelly i do not own that replica, i need some precise mesure to make the grip fit the gun :/ if you find a high resolution picture of the gun (side picture) + some reference mesure (from point a to point b on the hd pix, i need two or three refenreces) then i can give it a try for sure. lemme know
