https://revolverguy.com/ruger-9mm-lcr-field-report/I came across another article on a Ruger 9mm revolver, this one is about the LCR.
I can't tell if the Farnam article is about one of the other models since Ruger has done this with the SP101 and the LCRx version, but all of these are short run offerings that are not very common.
I like my 45 ACP revolvers very much and considering the 230 grain projectile, I am not sure what is up with the examples we see in these 9mm articles.
In the labs, we can both measure the dynamics of the weapons, and we have "drop sleds" we use to create standardized shock tests for the ammo.
We would have needed to run tests of both the pistol and the ammo to have an opinion of the margin of safety that would mean something, but here we don't have a clue.
All I can say is I will bring a set of calipers with me the next time I play with the S&W 929 which is an N-Frame series 8-shot design that runs moon clips and is popular in ICORE competition circuits.
This S&W 929 weighs roughly 44 ounces and the Ruger LCRx weighs roughly 17.4 ounces, not to mention the inertial mass properties would be just as dramatically different.
Since I brought that up, the SP101 shows 25 ounces.
Could be that the LCRx puts that much more acceleration on the ammo, or it could be that some ammo is low quality with respect to neck tension, IDK.
Since the 9mm Luger is over 100 years old and the standards committee had to herd cats because there were so many versions and inputs from all over the world, my opinion is that Ruger should take on the problem of rating the ammo to determine the risk in their design and advise their customers what to avoid and what they recommend as well. It would be harder to force the ammo market to meet a new and more difficult standard requirement compared to sorting out the needs of their revolver design. But this is just my opinion.
I didn't turn on to the moon clip revolvers till later in life, and regretted waiting so long. I realize trends in guns and ammo change with generations, and these days revolvers are not for everyone.
If I go to the range with the S&W 929, I arrive with the ammo already on the moon clips and none of the brass hits the ground. If you shoot it, it just puts a smile on your face and many folks went out and got one after trying it.
It is a great teaching gun for rookies in my view. It has an excellent trigger, long sight radius, is very accurate, and very gentle for folks who are just learning recoil.
I will warn you these are not cheap and easy to find either, but worth the trouble. YMMV
