Re: why no beretta love?
This is the sampling population I tend to deal with regarding 'issues' arising from the M9. Perhaps your experience with a onesy here and there or your company/platoon quals once a year/quarter demonstrate to you that an M9 is 'reliable', however, after pounding out thousands and thousands of rounds a month, month after month...
Most days, a group of broke-downs starts to clutter up.
Issues with the M9 service pistol starting with most serious and re-occurring:
-Locking block failures. Can completely freeze up the weapon (other times it can continue to fire). It happens way too often to be considered combat reliable.
-Safety/decocker is the absolute worst location for a combat pistol. Essentially two hands are required to operate the lever. Thus for troops who have to carry chambered round/on safe it is nearly impossible to conduct a speed draw and render the weapon capable of firing in the immediate. It is also nearly impossible to re-holster the weapon one-handed efficiently after firing because of the odd angle required to gain purchase on the lever by a finger. Furthermore, the double-single action trigger system is asinine in the modern era. NO weapon system on the planet should have TWO trigger pulls. Does your M4? Your precision rifles? Heck, your Ma Duece?
-Weapon system has (rare) predisposition for safety to become engaged during a tap/rack/bang drill (=dead mans gun)
-Trigger bar spring. Can fail and render trigger inop. Can be installed incorrectly/fall out on re-assembly. Obviously needs to be soldier proof but its not.
-Safety/decocker malfunctions when worn/used too much.
-Magazines. Seabiscuit has been beat to death.
-Grip circumference enormous, grip panels can loosen up if those tiny washers go missing, ought to be capture washers.
-Inability to change out front sight (tritiums). Addressed in later upgrades.
-No Picatinny rail. See above.
-Aluminum frame gets battered and accuracy can degrade. Inability to rebuild frame.
-Weapon system is particularly overly dependent on lubrication for reliable function. NOT the preferred characteristic for a combat pistol.
I have concluded based on experience over the years that the M9 is no longer ready for prime time.
