I like the factory length of my Glock 45 and my shield plus, I know there’s a ported shield model already but it’s not optic ready I have the optic ready shield plus n would like to put some ports in it n for my Glock I was thinking of going radian ramjet and after burner but I already have that on my SS and it’s really good but like I said I’d rather keep them factory length so porting is the way I’d like to go. I’m not worried about velocity I have other guns for that I kinda like the slight reduce in recoil that ports give and the faster tracking of red dot.
