Extended Magazine on 870 20 ga Mag Express

[Jack Ryan]

Does any one have an extended magazine on their 20 gauge Remington 870 express magnum?

How many does it hold now? What brand did you buy? Does it function through the whole mag well?

These fine folks make the best in the biz - NC Shotgun Extension Tubes

Make sure to get the barrel clamp, too. Otherwise, the extension and nut will work loose under recoil due to the shallow threads for the magazine cap.

I have an extended 12 gauge mag on an 870P, never had a problem with it.

Haven't had any problems. Don't recall off the top of my head how many it holds, sorry. Got it a couple of years ago from Tank's Rifle Shop:

LT-20 Accessories

Edit - I'm guessing 7 or 8 shots from looking on Tank's site (since I don't run over a 20" barrel on it).
