UpLULA Spacer for Sig P365, 1911, M&P Shield, 9mm

thingiverse

Spacer/adapter insert for Sig Sauer P365 9mm magazines (and others), used to enhance handling with smaller, semi-double-stack magazines in Maglula "UpLULA" speed loaders, eliminating the "slop" when loading these magazines. UPDATE 1/8/2020 - 9mm Double-Stack & Customizable: A thin-wall box version is added for some 9mm double-stack magazines. This version has been tested for fit on both Sig P320 and Taurus PT92 15-round magazines. Also, the FreeCAD source file for the Sig P365 is updated to simplify customizing the design for most magazine sizes that would fit the "box" design. Details are found in the "Customizing with FreeCAD" section below. The .stl for the P365 has been slightly adjusted to provide more clearance for the "Lock" button. UPDATE 3/26/2019 - Box Version & Shield/1911: After using my original P365 adapter, I noticed occasional problems with cartridges jamming "nose down" because they were being set to the back of the loader with the narrower magazine. The metal pressure tongue (depressor) forced the bullet-end down, causing the jamb. To fix this, I modified my design to move the magazine more forward in the loader, so the pressure tongue presses down in the middle of the cartridges. This worked much better! I call this the "box" design update. See the files with "Box" in their name - both the P365 and the Shield designs use this. Also, a version of my adaptation for S&W M&P Shield (box version only) and single-stack 1911 magazines is added. The original adapter was based on the design by dacinator (M&P Shield) for his sleeve. I re-modeled my adaptation from scratch in FreeCAD to support the dimensions of the P365 magazine, and add a few minor enhancements in fit. I've included all my CAD files (for FreeCAD), so you can make any changes needed for your specific tolerances or printer. See details in the "Customizing with FreeCAD" section below.
