It cycles fine in my G-19 but after reading your post and several others and looking at other data sources I am going to bump it to 4.4 with a 1.100 COAL and see how that works.4.0 gr of W231 is below start charge, even for lead load data. For me, 4.6 gr of W231/HP-38 and 115 gr FMJ starts to reliably cycle the slides of Gen3 Glocks with new factory recoil spring assemblies. Perhaps you are using 124/125 gr bullets or well used recoil springs?
Hodgdon load data
My 9mm reference load is with Winchester 115 gr FMJ and 4.8 gr of W231/HP-38 at 1.125" - 1.135" OAL.
Here's 1999-2005 Winchester load data comparing 115 gr FMJ vs JHP powder charges along with 124 FMJ.
