The last two times ive tested my carry piece ive had issues. S&W360pd
One issue was the cylinder release fell off, not a big deal since i don't carry a any more ammo.
The second issue was it only fired 3 rounds and jammed. I had to beat the case out with a hammer and punch. I couldn't believe how stuck it was. I believe it was Remington .357 PD ammo ive been using this ammo without issue. I put 200 various .38 .357 rounds through it cleaned it because i know you can have issues shooting .357 after shooting .38. I then fired 2 full cylinders and proceeded to carry. Once, twice a year ill shoot it, just to use ammo that has gotten wet at one point or another.when it does get wet i just dry the ammo clean the gun. Im not swimming with it or anything.
Anyway its not very reassuring, while its a pleasure to carry, if it doesnt work might aswell not cary.
I will say i did hit my mark on the 3rd shot at a 6" plate at 10 times the distance id every use it for defense. So technically i guess it probably would have do the job against 1 aggressor.
