Bullet pull is a fact of life.I see on internet forums (it has to be true, right) that there is an issue with revolvers shooting semi-auto cartridges. Supposedly recoil can cause the bullet to be pulled from the case and jam the cylinder. Has to do with the lighter crimp on the semi-auto ammo.
I've been thinking about a 9mm LCR and am wondering if this is really a significant issue or just internet fodder that's more a "possibility" than a real problem.
I used to have a Ruger Sp101 in 9mm . It was "OK" but I didn't care for reloads bouncing around in my pocket in the moon clip. They got bent easily and fouled on lint, etc as compared to a speed strip or (certain brands of) speed loaders. Putting the loaded moon clips in a pill bottle (as some suggest) just made them bulkier and harder to get too. In the end ( once the novelty wore off) I just didn't see where the 9mm snubbie had anything significant over the cheaper and easier to find +P rated 38 flavor. I have no desire for another but I do believe S&W is missing the boat by not offering one to those who do.
a 9mm bullet has much more power than a 38 special +P.
SATX, I have little doubt that the vast majority of people interested in a small revolver for SD would be more comfortable with one chambered in .38 Spcl. or .357. They are traditional, they are simple, there are no complications with moon clips, possible bullet pull issues, etc.
That being said, I do like the 9MM revolvers, and have a S&W 940 and Ruger SP-101 chambered in 9mm. The moon clips required are not an issue for me. Ballistics of the 9MM cartridge in these little 2" and 3" revolvers fall between 38 Spcl. +P and .357 Magnum. Over all good, bad? Each will decide, but most will choose a traditional revolver cartridge....
BTW, trigger pull with any manufacturer's production guns will vary. I have more than one S&W. No two with same trigger pull. My Ruger trigger is heavier, but just as smooth as the S&Ws. But someone else might have the exact same models, with better or worse triggers.
