Typically you see flared magwells made of billet aluminum and overtime get scuffed and dinged up pretty bad.
Reptilia Corp uses a high-strength, reinforced polymer that resist impact and wear.
Currently the Reptilia Corp Black Hole Glock Magazine wells are available for the Glock 19 and Glock 23 GEN3 and Gen4.
The Reptilia Corp Black Hole magwell also supports Polymer80’s mode PR0940C.
Support for the Glock 17 in GEN3 and GEN4 are expected to start shipping out late 2019
Reptilia Corp states “The Black Hole’s enlarged magazine well opening helps facilitate more efficient reloads without adding unnecessary bulk to your carry or duty sidearm.
Compatible with 9mm & .40-caliber GLOCK pistols, the Black Hole utilizes a unique rear spacer to ensure seamless fit and compatibility with both Gen 3 & Gen 4 frames.
