IMO/IME, I have shot various jacketed/plated bullets including Winchester FMJ and Montana Gold FMJ/JHP bullets for match shooting and Berry's HBRN-TP bullets will match or exceed the level of accuracy from other bullets due to the hollow base that extends the bearing surface of the bullet base. BTW, Winchester now sells "hollow base" 9mm FMJ bullets instead of flat lead base FMJ.
Glock 17 has longer leade and very smooth start of rifling and will accommodate longer OALs with RN bullets. But this means more high pressure gas will leak around the bullet before high enough chamber pressures build for more consistent muzzle velocities.
If you want greater accuracy, I would first determine the longest OAL that will pass the barrel drop test then try powder charges of 4.4, 4.5, 4.6 gr of W231/HP-38. BTW, I load for multiple pistols and use 1.135" OAL with 124 gr HBRN-TP bullet for "general purpose range practice load" but if I wanted to maximize accuracy for Glock 17, I would use the longest OAL that will fit the magazine and feed/chamber reliably to minimize high pressure gas leakage for the most consistent chamber pressures/velocities.

When Berry's 124 gr HBRN-TP bullets came out, I did an accuracy comparison test with the regular Berry's 124 gr RN using 4.2 gr and 4.5 gr W231/HP-38 at 1.135" OAL and Winchester SP primers -

Test pistol was Glock 22 with 40-9 Lone Wolf conversion barrel and all shots were fired off hand. Shot groups measured center-to-center.
