Well made extension - Herrington Arms Glock 19/26 2 Round Magazine Extension

These are well made, good looking magazine extensions, however the install process for these was probably some of the most difficult mag extensions to install and I have many different types and brands. However, once its on, it will definitely stay put. Overall, I'm happy with them, I enjoy Herrington Arms comps also, the only reason I gave 4 stars is due to install difficulty.
