Loading 9 mm for a Glock 43x what could be easier? I purchased a large number of 124g RMR JHPs A while back and have shot my way through 2000 Or so and determined that a COL of 1.08 inches worked well with 4.9 g of WSF. Shot reliably using several guns but not with my friends Glock 43x. A COL of 1.08 inches just barely passes the plunk test. And fails frequently. Mechanically this cycles through with a COL of 1.05 inches. My curiosity is does anyone know if I can shorten it up further or if I’m already pushing up the pressure? Since it is someone else’s gun I don’t think I should experiment. Thanks for your thoughts & happy new year
