I'm in the same boat as Cane Toad. I only read three shooting magazines Gun Test, American Handgunner and Front Sight (the USPSA magazine). All of them review firearms, and I trust Gun Tests first, then Front Sight (mostly because the top guys are reviewing the gear they shoot and win with) and then American Handgunner.
In particular, Gun Tests runs several tests I can replicate at the range. So in particular when they are trying out something I can rent, I can see if I get the same results. I've done that enough times to be pretty comfortable with what they do. I hear where Cane Toad is coming from, that they can be unforgiving - but to be honest, as a consumer of individual firearms I would be too if I had a lemon.
In fact, I was at the range today with my Dad and ran into a couple, who were both shooting Springfield XD subcompacts in 9mm. Now, I know other people that have had no problems with them, but in their cases both of them had their frames break. (One of them had evidently broken a couple of weeks ago and been replaced by Springfield, the second one just broke today.) Probably a freak incident, but they are done with Springfields all together.
Personally, I have a Springfield 1911 had have no complaints about it and I run it in Single Stack USPSA. I've never had a problem with an XD and know lots of people who are happy with them. So, my point isn't to malign the gun - any gun can have something happen. My point is that I actually like that the magazine really reflects the shooter as an individual buyer who expects the gun they buy to work.
Other gun magazines? Well, mostly it is just for the pictures.
