A fellow that does quite a bit of ammunition testing named TNoutdoors9 tests it in diluted SimTest.
He says the results are not much different then the 147 gr. HST
I'd rather go with the LE packaged 147 gr. @ $24.50 per 50 then $23.00 for the 150gr. "micro".
I believe that the Law Enforcement HST and civilian, use different propellant.
I have noticed a brighter muzzle flash and a different smell, with the civilian packaged 124 gr. 9mm.
Ya I agree with you, I've been purchasing the P9HST2 from target sports for around $.40 a pop (1000rds at a time). My ex wife is running a Shield and my gf is looking to go glock 43 or shield from her current G42 so I was curious if there would be enough performance gain to justify a box or two of the 150gr.
