I am considering buying one of the three supposid M4 Clones for a dedicated home defence shotgun and NFW can I afford a M2, M4, 1301 or even an A300 Ultimate patrol so a M4 Clone it is.
Ones I am considering:
#1- Stoeger M3000 Freedom Series pistol grip extended magazine
#2- Military Armament Corporation 1014 pistol grip EX/MAG
#3- Panzer Arms M4 Tactical Pistol grip EX/MAG
For those who have experience with any or all three which do you recommend and if you please a basic explanation as to why you recommend one over the other.
I have watched at least 10 review and torture/reliability tests for each gun and they all seem to function well with at least well enough with trap loads as a minimum power shell, but I did watch the MAC 1014 fire 1200fps trap loads very reliably as did the Stoeger if you held the Stoeger loosely while shooting. In my opinion if I actually God forbid ever need to use the firearm in a self preservation situation I would be using strictly #4 buckshot and 1oz slugs as I have a HUGE number of Active 1oz Foster slugs.
They are close enough in cost To MY Door price isn't really a factor. Looking for which one has the best chance at highest reliability and durability with tarp loads up to full power slugs and Buckshot . While yes I will test whichever shotgun I buy it for reliability, how well it shoots #4 buckshot and 1oz slugs, and shoot it +/- 100 times a year to keep familiar with it, I will not be burning up a lot of rounds through it on a regular basis.
This will be my goto HD shotgun replacing a old standard 21" 3" 870 12ga.

Well I think the choice was just made for me.
I just stumbled across a used but like new in box Panzer M4 Speed at a Cabelas. Called to day and spoke with the gun counter guy. I asked him if he could look the gun over and give me his opinion of its condition based on a scale of 1-10, he was nice enough to hang up go look the gun over and promptly call me back. He said he is the guy who evaluates all trades in guns for that store and he placed the condition of the gun at very good 8.5 out of ten. He said he gave it an 8.5/10 instead of a 9/10 because there are two small marks on it on the shell release lever and shell tube behind the factory tube/barrel clamp.

I had him ship it to my local Cabela's with his assurance if I didn't like it I didn't have to buy it and there would be no charges or fees. I have more than enough in Cabela's club points to buy the gun and 400 rounds of mixed 1300fps shells to perform a reliability test if I do buy it.
