Not especially Hollow point but the G17 GEN 4 I had would not function with the lower powered ammo and it had the current correct recoil set up. I sold it and bought a G19 GEN 3 it shoots everything.What makes you say that????? Are you hearing issues with the Gen 4's and HP?
I am sure Hollow Point wont make any differance. It is really wierd how some of the GEN 4 9mms have problems with the lower powered ammo and some dont, with and without the latest recoil spring set up. As I have said in other threads, I cant figure why Glock would think a 9mm needs a dual recoil spring. I havent heard of anyone using a GEN 3 single spring in a GEN 4, wonder if it would work?I have a new G19 Gen4 i used cheap ammo in it worked fine for me dont know how old is your G 17 is my 19 was made this month 7 - 4-2012 then again havent used Hp in it ill do it on my next excursion
