Hey folks. Last night was the first night I had my brand new 870 Express magnum run home defense duty. I had 4 in the magazine but no shells in the chamber (mine is 4+1 but do to safety, I just keep 4 in the mag). Is this a good system? Now keep in mind, the gun is COMPLETELY stock. Wooden stock and foreend (wood is amazing color and quality). The barrel is 25" and the overall length is 46". I have a nylon side saddle that sits on the stock that gives me 5 extra rounds. I have 2 snap caps that I will play with and practice loading (before all the mothers chime in, YES the gun is safety checked and all that jargon, so please save both of us some time and don't make a comment about that.) I want to turn this gun into a semi-tactical shotgun. I don't know if the express magnum is strictly hunting, or if it is marketed also as home defense. Now obviously an 870 is an 870 so it will get the job done. I am not too concerned about the mag capacity, because 4 rounds of 00buck will send the guy running, and if need be I have the extra shells around. I plan on putting a magpul MOE foreend on it. Goes on amazon for $29 (you guys will come to find I am an amazon addict). Will that foreend work on the express magnum? Another thing is an extended mag tube. I just got word that a mag tube will not work on the hunting 870's because of the dimples in the spring. So is this the same with the magnum? Will I not be able to add a tube extension? And advice is purely appreciated. This is my first real shotgun and first DEDICATED home defense firearm. PLEASE leave any tips or anything that will help. Thanks. You guys are amazing and have saved my ass a few times.
