I stopped reading gun and car mags years ago. With both you get inconstant reviews. With car mags you had unattainable 0-60 and 1/4 mile times in the mags that had HUGE advertisements right next to the review. Basically one mag would say a 1/4 mile in 10.9 and another saying we could barely hit the 12's. A second+ is a huge difference.
With gun mags you would get these glowing reviews of guns that the LGS hated. "We sold X-amount, more then half had to go back for warranty work and we have a bunch of ticked off customers". Being that everyone in my family is a member of the NRA, we get American Rifleman, American Hunter and America's First Freedom every month. Basically there is always something to read in the bathroom and it has crossed my mind that our mail person probably thinks "pyscho house" but my household hasn't had a piece of mail missing in years.
I personally like American Rifleman. One of the reasons why and recently was Novembers issue, it was a review of ammo and not even a gun. I had heard and read nothing but bad things about the HST .380 for micro pistols. The "technical" article at first looked like it was going say this .380 round could shoot down a Apache helicopter but after a rather long article for a specific round, it agreed with the common perception that it was a marketing ploy backed by expansion tests and actual chrono tests from a 2.75" barrel that didn't even come close to what Federal advertised. A truthful article to me based on what others had said and written.
I find that the best source for gun reviews is actually YouTube. You will get a vast variety of different people firing different guns and loads. A new gun is like a new car in a way, it might rely on the name brand and be a jam-o-matic. It might be a brand you personally cant stand and be a great gun for your needs. I find the gun reviews on YouTube to be surprising amusing and you get many points of view. Plus if everyone has problems with a certain gun and they have videos of it constantly jamming or it just being a POS then you know there is an issue. The R51 is a perfect example of that. Unless you have to be the first one to own a gun that just came to market, wait a few months and there will be at least 5 reviews on YouTube.
