Not all designs should be for profit. We designed the XD to increase the capacity of the magazine while using the factory spring. We offer the .STL file for free for those of you with a 3D printer to create the part. We recommend printing with 85% to 100% infill with supports.


*Note: this is for the digital print file only.


*IV Engineering claims no responsibility for incorrect use of a firearm. 


*Follow all laws regarding magazine capacity and manufacturing of "high capacity magazine". It is your responsibiltiy to know the laws and follow them.
