Popple holes in Glock 19

[Kepo]

Hey guys, 

I have a Glock 19 that I use for home defense and range use that has a kkm barrel and one of their 2 port comps on it. I was thinking of drilling some popple holes in the barrel, but was wondering would it even be worth it since the barrel is so short and I have a front sight? I plan on reloading for this gun and using hot loads for gas to work the comp 115 or 124 gr hs6 powder. I have seen enough videos on YouTube of people using this setup with factory ammo and find it quite ridiculous. Why add the comp if your going to use factory ammo? What is the typical hole size for 9mm and how many? Does anyone think this will be worth the effort or will it have little to no effect since the barrel is so short? Don't need to make any power factor just want it to be ridiculously flat!
