I'm not looking to "combine" shotguns. I am looking to see if the barrels for the m1 field, m1 slug will fit onto the M1 tactical so that if I decided to use the M1 Tactical for hunting I would have the flexibility by simply changing the barrel to the appropriate one for the need that day, without having to buy 3 shotguns. Again I prefer the feel of the pistol grip so I'm hoping to be able find a Benelli that with fit that.
Now for home defense. Numerous experts, and guns and ammo has done numerous testing for the ideal home defense weapon and time and time again they come back to the 12 gauge shotgun with a short barrel as the best choice. Why? Because one thing you have to consider is that behind the intruder is often a wall that either has a family member whom you are trying to protect, or in many cases a neighbor. The 12 gauge loaded with #7 1/2 or #8 shot creates an ideal weapon with the stopping power needed, and yet has a low amount of penetration through walls when compared to pistols. If a shot were to miss using a shotgun increases the safety for those you are tryign to protect. Now like most people that have a weapon for home defense, I certainly pray that I never have to use it. However I want to have something reliable and trustworthy.
I currently own an HK USP40 compact and have my CCWP. I also was a part of the tactical response team on the George Washington CVN 73 and we were a backup for the marines and received training on CQB and were armed with shotguns and 45's. Natually given the potential combat situation the loads we used were 00 Buckshot. Given that all walls were steel this was acceptable and we even trained how to shoot around corners to clear passageways by richocheting the shots off the steel walls. Naturally you cant do this at home, but numerous experts tend to agree that the 12 gauge with the 7 1/2 or #8 shot is still the best shoice.
Thanks for the feedback so far.
