I have shot it in 9mm and seems good. it has red primers for some reason though. home much is it for 45 and were do you get it from?
I've tried WWB, Winclean, American Eagle and UMC and the only thing that shoots better in .45 than S&B out of my CZ is Remington Golden Saber in 185gr - but you're not exactly going to put that stuff downrange on a regular basis. I've found S&B in 9, 40 and 45 to be at or near the top in terms of accuracy and reliability in my pistols (CZs, Sigs, and HK).
Hey Cbabes, is that an extended mag in your p345??
