Shot the 17 with ZEV RDS slide this past weekend in a wet and rainy training day. I had been doing more dry practice lately with the RDS handguns and wanted to see how I've improved (or not

) in speed picking up the dot and tracking the dot better in multiple shots. Overall was happy with both, but also noticed that a couple other aspects "needed work".
Regarding picking up the dot quicker on the draw, I have been doing a bunch more dry practice working on both speeding up the draw and picking up the dot and breaking a shot. There were some drills that we shot that were perfect for that. Good news is that I was picking up the dot quicker, but bad was that in review of the video after, I was slowing the draw in the last 4-6" before extension. I think recent issues in picking up the dot on the draw had been because I had been doing a lot of shooting with my CZ75 lately, which has a distinctly different grip angle as Glock. Not an excuse, but more observation. Doing more dry fire with the 17 and 19 with RDS lately has helped. Then regarding draw speed, was concentrating on firming up my grip and "vice action" for shooting flatter. Upon review of video on my draw, I was slowing down the gun maybe 4-6" before extension. Something I noticed as "not smooth" and an instructor friend picked up on as well. Since the strings of fire when I was taking the video was draw and shoot multiple, I believe I was initiating the grip pressure and vice action before full extension and the muscle tension slowed things down. I did more dry practice another day and noticed that if I started the pressure early, it definitely slowed things down. Something that I'll have to work on.
Regarding tracking the dot better in multiple shots, I was trying a tip to keep the dot in the lower portion of the RDS window. That that would allow a little more forgiveness in the dot leaving the top of the window. I can shoot the 17 pretty flat as is, but there are times that I do notice the dot disappear and reappear from the 12 o'clock. That's particularly when doing multiple target transitions. My habit is to center the dot in the window, like with rifle RDS. The iron sights on my 17 slide is quite low in the window, so that was easier. However, the iron sights on my 19 slide is much higher, so having the dot in say the lower 1/3 of the window puts the dot on the front sight blade. I noticed this when dry firing and I wondered if it would bother me. However, just like shooting rifle with RDS co-witnessed, I didn't seem to notice when shooting both eyes open. Yeah, I did notice the dot being on the front sight here and there, but generally mostly saw the dot on the target.
While I did notice some improvement on speeding up the draw and picking up the dot, when we started doing multiple targets, I noticed that I started missing some shots on target #1. In strings of fire with 2 hits per target, I think I was getting too quick on the transition to target #2. On missing the first shot on target #1, I think I was either getting ahead of myself (not good grip on draw, yanking trigger, etc) or pushing things a bit too far and beyond my capabilities and ending up with a fast miss. There was a competitive aspect to these drills, so while that made it fun, it led to many trying to push things to win and having fast misses.
It was rainy pretty much all day and that always makes things interesting when shooting. Didn't notice it much with regard to the RDS with water on the window. There were definitely times when there were water droplets all over the inside and outside surfaces of the window and at times it would partially distort the view, but didn't really bother me. I know in the past with shooting my LPVO in the rain I would notice that the droplets distorted things a bit, but not really with the handgun RDS.
Shooting one handed is one aspect where the RDS really helped. Though for some reason it took slightly more time to pick up the dot shooting lefty at first, but that became smoother with some practice.
Fun day on the range with the RDS handgun. Now I'm considering (not that seriously) another handgun with RDS.
