Holosun 507k compact red dot - Holosun HS507K X2 Compact Pistol 2x 0.58 x 0.77 in Reflex Red Dot Sight

First of all Opticsplanet is fabulous to do business with. I'm an old school 1911 shooter and am somewhat new to the use of Red Dot Sights. I ordered a 507C to put on a S&W CSX-E Micro Compact Pistol when a 507K Compact Sight was the better fit. Opticsplanet did a quick exchange for me without any extra fees. I have run a few hundred rounds through the pistol and everything has run flawlessly. Thank you-Jim
