Ammo Question - Polymer coated lead?

[Survivor87]

So, I have a question for those more knowledgeable than myself. I'm searching around the interwebs looking for bulk ammo for my M&P Shield, and I came across a site that offers REMANUFACTURED 9MM 124 GRAIN RN 500 COUNT BULK AMMUNITION and REMANUFACTURED 9MM 115 GRAIN RN 500 COUNT BULK.

The sites reputation is strong from what I hear, AmmoMarketPlace.com, recommended by my Point Blank Self Defense instructor, who buys from them all the time.

Other than the 124 vs 115 grain, which I understand, is there a difference between these two? Is one better than the other?

Thanks so much for any input.

There should be no difference. Just shoot and practice with the same weight what you carry for self defense. That is good pricing.

Thanks Raisin. Yeah it's definitely good pricing. I figure if the instructor of the course uses them and orders from them regularly, I can feel pretty confident in the quality of this site and their cartridges.

I've used polymer coated 9mm. Remanufactured from FedArm, I believe. I've fired about two hundred rounds now without any problems. Got it for a great price at the time.
