What sort of mount are you using? I just picked up a 590 retrograde with 18-1/2” barrel a few days ago and am interested in adding a light as well. Been looking around the ‘net and have found the GG&G 590 flashlight mount and the CDM Gear MTR - Mossberg 590 Magazine Clamp with 3-Slot Rail/Flashlight Mount. But haven’t found a Canadian source for he former, and the only Canadian source I’ve found for the latter charges almost 3 times the US price. Any other options I could be looking at?
It'll be moderate use. More than an occasional range visit but I don't expect it to see as many rounds a season as my skeet / sporting clays shotguns (3K+ rnds).
