knurled ring like the middle?
It's called a cannelure, it's there by intent. The idea is it prevent setback and it is why you see it on premium SD/duty ammo, that often gets rechambered multiple times.
Cannelures come in various ways, sometimes it's a smooth ring other times it's knurled. Depends on manufacturer.
Nothing yet...... middle end of Feb.... maybe..crossing my fingers.
This is not intentional and neither is is a problem. If the round fits in the chamber, it's OK.
Sometimes a thing called "stacking tolerances" gets you. When loading a round, if the brass is sized just a little on the small size, and the bullet is a little on the large size, this can happen. The bullet spreads the brass a little and that ring forms as the bullet is pressed into the case.
As long as it chambers OK, and isn't overloaded with powder, it will fire just fine. The "ring" has nothing to do with how much powder is in the case. You could only tell that by disassembling the cartridge.
These are some casings from rounds I fired:
Looks bad, right? Not at all. The .40S&W generates more pressure than other rounds. So, because these were reloads, the case had already been weakened. Because the chamber takes the force, there was no hazard.
Now, sometimes a cartridge case gets mashed a little as the bullet is inserted. This crinkles the case and makes it so it won't fit in the chamber. These are not dangerous, but could get stuck in the chamber and won't extract easily.
What you pictured shouldn't be an issue.
Ok, now walk over to S&W and tell them to make me a 638.........
but I sold it to a friend that was hounding me for it... I love my 351c, great pocket gun or iwb-owb... also it's kinda pretty.... the lightest gun I own... and 7 shot of fury!! After that, for the pocket, I use my BG380 and another I think a 637Pro, neat little ported barrel...
I cant wait to get this 9mm Shield. Its exactly what I wanted in the first place. But I certainly didn't want to wind up getting it this way. I hope this never happens to anyone again. You just don't know the feeling till you get that big shock to your hands. I'm thankful that I wasn't hurt or my Dad that was standing next to me at the time it happened. Thank all you folks out there. I hope one day something good happens to you all like this has ended for me.
Ok, looks like on order... that was my first revolver, bought for the pocket. Never really used it much, maybe cause it's one of the ugliest guns ever made...
Just getting impatient Mr. C. Yes it's ordered.
You are correct, it is butt ugly but that humpback will go right in my pocket.
It's ugly and beautiful at the same time.
That's not a wheel gun......., this is a wheel gun!!500sw - 4"
I don't have a Shield, but all of my 9mm ammo is 147gr. It is not +P and the 147gr doesn't make it so. Therefore, it should shoot fine in the Shield.
