Is a GLOCK Conversion Legal?

Before doing any conversion on any firearm, be sure to check all federal, state, county, tribal (if applicable), and municipal laws first! Your conversion may not be legal, no matter how easy it is to do. Many conversions may also make your gun an NFA firearm, which will require extra legal steps BEFORE you make the alterations.

Does GLOCK Make Conversion Kits?

Although at this time GLOCK does not make conversion kits, there are a lot of conversion kits for GLOCKs available on the market. Some of the most popular are the CAA Micro Conversion Kits (MCK). We carry more top brands like Advantage Arms, Polymer80, CAA USA, and Recover Tactical!
