Design Upgrade: Pistol Magazine Insert

shapeimage_11 I’m making a small but significant design change to the Pistol Magazine Insert. It’s a piece of gear that I use on a regular basis, as described in my EDC post on this blog, and while working on a batch for a couple of customers, I noticed a chance to make a small change that would lead to big improvements in retention.

The current version of the Magazine Insert already has very good retention characteristics which I would put against any similar item in it’s class. It works with the use of resilient, 3″ wide webbing sewn to pull tightly against a magazine which rests on a non-slip surface backed by an HDPE support. To this, I’ve added a thin layer of closed cell foam padding, sewn between the non-slip and the HDPE backer. The foam gives slightly but it also pushes back against the surface of the magazine for much better contact and increased friction between the surfaces. The combination of inward pressure from the woven elastic webbing and the slight outward pressure of the foam, both acting on the magazine in opposition to each other creates compression that leads to better retention.

I’m constantly tweaking and changing the design and customer feedback also drives a lot of improvement. It’s just another example of how actually using the gear on a daily basis, and building it from the perspective of an end user leads to innovation.
