just want to share my new promag/archangel 7 rounder shotshell carrier installed in my590-as well as my personal thoughts about it..u might want to check this out since this is a very good option amongst shotshell carriers in the market right now...
thoughts on the promag/archangel sidesaddle:
-very easy to install
-hi quality item based on heft and finish-looks like it will last the lifetime of the firearm
-looks like its expensive competitor-mesa tactical, tho this one is made from sturdy and heavy polymer not aluminum
-has individual tension screws per shotshell to adjust to ones preference in terms of shotshell retention-a first in its class
-7 round capacity instead of the usual 6 without sacrificing any space or ergonomics
-personally i felt it balanced the shotgun better-no more heaviness near the muzzle
-I was still able to use my grovetec qd cup pin sling attachment-a definite plus!!
- and the best, its cheap but definitely not cheaply made! i got it for much less the price of a locally available tacstar sidesaddle..
