Reptilia Corp. Black Hole Polymer Magwell - Glock19 Gen 3/4 - Black

Reptilia Blackhole Magwell for Glock-19 is compatible with Gen 3 and Gen 4 Glock 19s.  

The Blackhole is a low-profile, polymer magwell meant to take serious abuse.  The forward rake helps anchor the hand without having a large heel, found on other magwells, that reduces concealment.  For a concealed carry firearm, the Blackhole gives you all the benefits of a magwell with none of the drawbacks reducing concealment.
