Just a bunch of nonsense really. The seals actually prefer the 226 over ANYTHING on the market. They have the budget but still use 226's.
Handgun 101 is that owners of their choice of firearms bark and bark loudly. The worst offenders, in my opinion are the Glockophiles. They bark like nobody else. You'll find the same snobbery, to a lesser extent among the HK aficionados. Then there are the 1911 folks, the Sig folks, etc. Then there are caliber snobs (9mm guys being the worst), striker fired snobs, etc.
When I see youtube videos of guys burying their rifles and handguns in the mud for a torture test I laugh. I've seen guns run over (SigPro), guns literally shot (the Russian FPS guy), guns thrown in lakes, swamps, deep mud, etc. It's just stupid. If you are military and about to get dropped in the sand, well, big difference to a sheepdog or a LEO.
Whether striker fired or hammer fired the best firearms are numerous. M&P's with the apex trigger kit are solid, as are the new Walthers (PPQ is getting a heap of praise due to the trigger), Sig P series and Pros (The Cohen guns, 290, 238, etc, to me aren't as good), HK's, Glocks, XD's, Beretta's PX4 line. These are all quality pieces that are going to go bang when you fire them.
You might find some real discrepancy shooting any of these firearms uncleaned for 1k rounds or more but in the real world most clean their guns more regularly than 1k rounds. Myself I clean them after every round trip because I'm anal, use grease on the rails, along with oil.
Take what you read from gun guys with a grain of salt. Some are full of it, some are biased, some probably get free guns from some mfr.
