Best glock gen 5 magwell hands down..... - Killer Innovations Velocity For Glock 19,17,45 Gen 5 Magwell

Tried a lot of other brands....this was the only one fits perfectly...doesn't slip off the front of the gun and doesn't squeeze the grip and make the mag hard to remove....not to mention it looks great, still works on a carry gun and isn't too bulky for concealment.
