splits/recoil management on glock
picked up a g17 gen6 a little over a month ago to edc. as of right now I shoot a shadow 2 in CO. I used to edc an m&p 2.0, and previously shot a pdp 5" in CO. so that is the world I am coming from but now wanting to carry the glock and sold the m&p. for some reason, the glock just seems slow. idk if it is the trigger or what, but my splits are in the .28-.35 range when i'm trying to shoot on confirmation 3 (dot). when shooting my shadow 2 or PDP my splits are in the .16-20 range for confirmation 3 (dot). My shots are also hitting much less consistent, up down and left right, roughly within 4-8 inches of the center of the A zone at 7 yds with the glock. with the cz or pdp I am at the center of the a zone within 0-4 inches at 7 yards with much faster splits. I want to shoot the glock to the best of my ability but i don't know what is holding me back. has anyone had a similar experience switching to glock? were there any tips to adjusting to the different platform. i am trying to get used to the trigger as it is much different than what i'm used to. the grip angle is not that big of a deal as I just adjust how I index the gun and that seems to solve it and it points just fine as I have been dry firing it almost as much as I do my S2 for carry optics.
tldr how did you guys switch to glock and become proficient with it?
