Does anyone know of a duty grade magwell for glocks gen4? I was looking at the Raven Freya or the Agency magwell specifically but haven't seen many others. Also, how hard is ripping out mags due to malfunctions with a magwell like this? Secondly what magazine extensions does everyone run? The taran seems to be the best available. Note the magwell is for a carry gun and the mag extension for a backup magazine not for competition. Thanks!
