See? The rear sight has no notch. Bit of a sway back. You might wander that big front sight around in that shallow saddle and not line it up with the post to make a perfect lollipop. Also, that front sight is BIG. It covers a lot of the target. You aren't going to aim at a bad guys left eye and decide against that and shift to the right eye when he's 20 yards away. You know what? I'm not good enough to do that anyway. So the problem the sights present are a bit moot.
Plus, they glow in the dark. They almost back light my face they are so bright. That's an improvement, so if performance is not too negatively impacted, the switch to XS will be considered a good thing.
Anyway, here are the targets:
I aimed at the lower right shoot n' see first for quite a few mags to warm up. You can see the usual T-Bolt shooting flaw with 'flyers' outside the target area, but still some good-for-me work otherwise. I relaxed and shifted to the top left target. There I concentrated on gripping tighter and just feathering the trigger to break the shot. With noticeably better results if still low and right. I'm getting better at that light trigger work, and can do it on demand most times. I don't know if I could under stress without a lot more habit forming trigger work.
Here is the second target.
I started at the upper left shoot n' see. Then I did one mag each at upper right and lower left. All those and the previous target were at 25 feet. But for the lower right I pushed the target trolley out to 60 feet and shot the last 16 rounds. Since the sights aren't as good at distance, and I'm not that good at shooting I expected disaster. I was pleasantly surprised I shot as well as I did. That green encircled area is only 10 inches wide at the widest.
Verdict... XS Sights are a keeper and I'm glad I got them.
On a side note, I am slowly 'getting' my trigger pull. And about time. I need to accelerate my establishing of pathways with a better trigger pull so it's second nature.
Another side note, gripping 20% tighter leads to more blisters. One on my left thumb from where it rests on the safety. One on the left palm where the mainspring housing rests. Poor baby...
