ForTehNguyen's (1100 TAC-2) picture is an 18.5" barrel with a +3 extension. The TAC-4 (what I have) has a 22" barrel and a +4 extension.How many shells does that magazine extension allow? What is the length of that barrel?
I'm looking for a magazine extention to match the length of my current barrel. Would that be a 7 shot, 8 shot or 10 shot?
It's longer than 26". I do know that. Yes, it has a rem. choke. Chokes are something I don't know a lot about other than it changes the shot pattern. What I'd like to know is what shot can you use/not use with various chokes. Would it damage the gun to shoot it with the choke removed? Also, I'm assuming slugs and chokes are a no-no.How long is the barrel? Looks like a 28"? It should be a 4 in the tube, 1 in the chamber as it sits but it could have a 2 shot plug in it. If it has the plug, it was used for bird hunting. Does it have the Rem Choke or is it a fixed choke barrel? Easy to check, the muzzle will have 4 indentions if its a removable choke (Rem Choke).
As for a mag extension, unless you really think zombies are coming in your home, 5 rounds should be more than enough. Get a speed feed stock if you need more.
