SPD MAGS Magazine Conversion Kits with Built-in Mag Loader
Anyone who has ever loaded a double stack single feed magazine will confirm that it is not the easiest magazine type to load, to say the least. No wonder why magazine loaders of many different styles exist that make loading ammunition in such magazines easier. SPD MAGS of Kerrville TX is another company that offers a solution for this issue. They make handgun magazine internal parts replacement kits with a built-in mechanism that makes the loading easier. Let’s see how the SPD MAGS conversion kits work.
Magazine Loaders @ TFB:
SPD MAGS set out to invent a baseplate for an OEM magazine that would make it easy, fast, and convenient to load, without help from any other tool. After 4 plus years of research and development and 3 patents, the result is a is a Kit that installs in the magazine with the same reliability and durability as your OEM mag, but much more enjoyable to use.
SPD MAGS conversion kits are drop-in assemblies that are installed into OEM magazine bodies. As seen in the pictures, the follower in the SPD MAGS conversion kit is connected to the baseplate via a wire. In order to relieve the tension from the follower and make loading the ammunition into the magazine easier, one must turn the dial at the rear of the baseplate clockwise which will pull the follower down compressing the spring. After loading the ammunition, the dial must be turned counterclockwise to release the follower. The video below shows how to load a magazine equipped with an SPD MAGS conversion kit. Their YouTube channel also contains videos showing how to install these kits into OEM magazine bodies.
SPD MAGS currently offers conversion kits for Glock (G19/G17, G22, G23, G43X/G48), SIG Sauer (P320, P365) and Springfield Armory (Hellcat/Hellcat Pro) magazines with versions for Smith & Wesson, Shield Arms and Magpul magazines being in the works. Regardless of magazine make and model, the MSRP of SPD MAGS conversion kits is $39.95. These conversion kits are made in the USA and come with a lifetime warranty.

This seems like a idea that didn't go through an improvement phase once they got to version 1. Just looking at this, you are introducing things to the internals of the mag that could induce a malfunction, also the demo video shows that when you pull the follower down, without the upward tension of the follower, the rounds fall irregularly into the mag. This could lead to a improperly loaded mag, leading to malfunction.
If you wanted to stay with this design, it should be geared so that 1 turn = 1 round in follower travel. If I were to try to improve the design, I would ditch the internal cable altogether and build some kind of external tool to assist with loading that could fit into the base plate (not sure what that would look like off the top of my head). However, as many have said the UpLula devices are already an elegant, simple design that meets all these goals and will work with most magazines. So at a certain point you are designing solutions for problems that have already been solved.
Spelling "injection molded" incorrectly twice on their graphic in two different ways truly shows how outside of the box this company is willing to be.
