My 2 cents, information may be dated.
My service era was the last half of the M1911, Colt .45 APC era, and the first half of the M9, 9mm, Beretta SF92 era.
Honest confession is the that favoring a particular firearm is like favoring your mother’s cooking.
Moving on to another firearm is an adjustment.
The biggest proponents of the 1911s in the military are the guys who had that as their primary, or predominant weapon issued in their career.
Same thing with the Beretta.
I retired prior to M17/M18, 9mm, Sig P320 era being issued.
I heard shortcuts were taken on the run up testing / proving trials for the Sig contract, and that there were some problems subsequently.
I don’t know all the details but, that created some hesitancy on my part to seek those items for myself.
Regardless of any issues, or corrections if needed it’s like hearing a particular make, model, year of a vehicle is a lemon, and avoiding it.
If they had problems, and fixed them, I cannot speak to that.
But, I can attest to preferences, and biases for particular firearms exiting.
Digression here:
Just like your mother’s cooking, people develop their tastes.
Some people are more adventurous than others, willing to try new experiences more than others.
Unbiased, honest opinions maybe harder to find.
Like being subjected to MREs, and out of necessity having to endure them, made me a lot more willing to experiment with new foods, and different cooking styles.
Anything was better than the original, unimproved MREs.
We had alternative meanings for what MRE stood for: Meals Ready to Eat is the official version.
Reminded me of a line in Crocodile Dundee about roots: “Tastes like
but, you can survive on them.”
Alternative meanings: Meals Rarely Eatable, (taste)
Meals Requiring Enemas (very constipating),
Meals Rejected by Ethiopians (even starving people could not tolerate them)… you get the idea.
I once bright one home as a novelty for my sons, we decided to give our German Shepherd the “ham slice.”
He was a Billy Goat when it came to eating, had a voracious appetite.
He looked at it, sniffed it, and walked away several times, sat down with the most dejected look at us as if to say: “Was I a bad dog, what did I do to deserve this?” Case closed.
They since made some improvements, and more variety, since being in the field for extended periods without cooked food the novelty wears off, and the rotation gets tired soon.
But, for short hunting trips a few times they are sustainable, and surviverable.
My wife, God Bless Her, whenever I returned from long field tours always made her signature Lasagna (to die for), for me.
