Right eye dom I think. I was noting that I was closing my left a lot. My Glock is a .45 Glock 21 sf. I shot best when I just took a second and relaxed taking a breath and letting my grip loosen. I need to remember all the old things I was taught, told and figured out when shooting more regularly. The range didn't allow for rapid firing so I couldn't shoot in bursts at all, which is good and bad. There were also a lot of people shooting beside me and the loud thumps of others firing bothered me abit. Not sure if there is a conversion kit for the Glock 21 to .22. Reloads aren't really an option, this place was VERY picky about what ammo you use and of course my shells ejected into the range... mostly, caught a few in the head! LOL
When I head down to Central California and visit family the cheaper range ammo will be an option. There are off the side of the road and into the mountains shooting places there.
