I run a slide ride Deltapoint and really like it. I wouldn't suggest a slide ride unless you go with a durable brand optic, they're more expensive, but worth it in my book. I have no problems losing the dot and I run a 3.5 moa. Also, no holster problems, it improved my shooting, and helps with my older eyesight too.
