See I have read how "unreliable" semi autos are, especially gas operated semi autos, and IF you were gonna get a Semi auto the only reliable way would be to get a Recoil (inertia?) operated autoloader like the Benelli (M2?)
Bollocks!! Hardee harr harr HOGWARSH!
My first shotgun was my best, the Mossberg 930 SPX. It is a Gas-operated autoloader, and it supposedly has something called a "self-regulating gas system that vents excess gas to aid in recoil reduction and eliminate stress on critical components." - that's direct from the Mossberg website. I have been told Mossberg 930's gas system is very good for adjusting on the fly between 2 3/4" shells and 3" shells, and also different loads. that part i can confirm. I haven't popped too many 3" shells thru my gun nor really mixed them when I did, but I have shot ALL VARIETY and MANNER of 2 3/4" shells, light loads light-extra-light loads, slugs, Buckshot, reduced recoil loads, etc. etc. and it's been GREAT- I mean GREAT. I am talking about shooting a few mag tubbes full of standard 00 Buck, straight into a 25 pack of 8-shot Bird shot target loads (Cheap cheap!!!), into some reduced recoil loads, into home defense/personal protection loads, then some Hornady TAP premium HD rounds which are quite small sized compared, and Fiocchi buck shot which are also smaller sized, all FLAWLESSSSSSS, then some regular 00 Buck Winchester to clean it out again. ABSOLUTELY RELIABLE Ive not had ONE SINGLE PROBLEM with my 930 SPX. How can u say its not reliable, and its GAS OPERATED?
NOW, let us compare the Benelli M2 Tactical for example, a competition for the 930 SPX. Except its MORE THAN DOUBLE for a very similar gun. I was shown this gun when I was looking for my first shotgun, I had read on GlockTalk that EVERYONE in early 2010 wanted the 930 SPX... it was WHAT WAS GOOD IN THE STREETS SON!
Anyway I asked around, no one in NJ had them (turns out they're not NJ legal, loL) and some punk kid is like like, that gun sucks, we won't carry it cause it sucks so bad (Liar liar it wasnt AVAILABLE TO YOU) but we have this much better one, try this M2 Tactical by Benelli! Oh instead of $600-$650 its $1250-$1300. Oh how nice. anyway the gun was the truth, sexay and smoove. BUT- Recoil Operated. What that means is you get a lot of Feedback in the gun, Recoil you will feel. PLUS, if you don't shoulder it properly and BRACE for the recoil, it will not operate properly. So not only will you feel it, you NEED to feel it . So this is supposedly more reliable, but IMHO by definition that makes it LESS RELIABLE if it needs to be operated a certain way to shoot properly. OH YEAH It actually advertises/admits it wont use light/small loads. So it's not even versatile. And Gas operated guns inherently use less recoil felt, because they vent some of the recoil to cycle the action (Its the system)...
So after all that, I can't say I agree with Semi-autos bein less reliable. My 930 SPX is perfect. Oh and I spent a day shooting skeets with a buddy, he had his stepdad's Remington 1100 that the stepdad got when Rem 1100's were brand spanking new and the best thing out. Wiki says the 1100 came out in 63. The stepdad was a police hossman bossman and said he bought it when he was a young officer, early 70s. The 1100 was beautiful, great wood nice mid-length barrel, 26ish... and let me say. We put about a THOUSAND ROUNDS of the dirtiest dirt cheap loads possible. No cleaning, no lubing, just took an 1100 that was 30 years old, and had been sitting in a box for how many years? And started blasting away. never a failure. I wouild buy an 1100 simply because of this.
Having said all that, I do believe everyone who buys a Semi-auto shotgun should have a pump as a partner/backu0p. I will be probably getting a Benelli Supernova Tactical (I had purchased a Benelli Supernova tactcail/Turkey gun, it was SO AWESOME just a little too big for me, 24" barrel and big big Shoulder-pistol-gripped-stock, I had to dump it) but I would also like a Mossberg 590A1. .. having that pump backup, like a quality M590A1 or a SNT, will make u very happy and impervious to anytyhin.
