    The Holosun 509 is a great sight for numerous reasons. The two key features that set it apart from the competition are the reticle and the emitter is enclosed. I like the reticle because the outer ring makes it very fast to acquire. The dot is still small enough for precise shoots. The other sights that have exposed emitters are easily fouled by rain or other debris.

    Absolutely did the trick. Great optic easy to aquire and accurate.

    I recently purchased the 509t and dont regret it. The optic has been great so far and the summer sale is the best price.

    My only complaint is with FEDEX as there was a minor shipping delay. This delay was not with C&H but appeared to a minor FEDEX error.

    Overall great product and great experience. I will definitely make future purchases with C&H.

    Great deal on a great sight. This is the only sight our department is currently considering due to the dual glass panes that prevent the problems many sights have when it starts raining or snowing.

    I ordered the sight and it was on my doorstep 2 days later. I received notifications all along the way. Thanks.

    This optic is the best I’ve used. I had a Trijicon RMR prior to this, and when it did duty on my home defense pistol, dust would gather on the screen and emitter and the dot would star out and made the dot look worse than my astigmatism did.

    I replaced it with the 509T and a CHPWS M&P 2.0 mounting plate and it has been phenomenal for dot/reticle clarity and I haven’t had to worry about cleaning the emitter like I did with the RMR. The Sage Dynamics review showed me the potential, the summer sale made it a reality. Thank you for the awesome sale and the fantastic mounting plate!
