Alright folks, I apologize about the delay in testing results... I was waiting on the latest batch of test ammo to ship. I tested the following loads through my Gen5 19 MOS, using the same (2) test sample Gen 5 G19 10 round magazines (w/ 2183-2 Orange followers):
50 rounds Speer 147gr G2
50 rounds Hornady Critical Duty 135gr Flex Lock
50 rounds Federal 124gr HST
200 rounds Winchester 115gr FMJ White Box
*the HST by far, had the largest diameter hollow-point of any rounds fired to date*
ZERO malfunctions/or failure to feed stoppages with any rounds today.
Stay tuned for more testing... so far so good!
