Everything you want in an optic solution. The IOS is adaptable to your needs and allows for a low profile RMR mount with the versatility to switch rear sight in a matter of seconds. With the dovetail cut in the slide each plate can be removed and still return to zero, allowing for quick and easy switching of rear sight without sacrificing aesthetic or function. 

"I have shot a lot of nice 1911’s and can honestly say none compare. It is beautiful, but the way it functions and shoots is amazing - Thank you! The IOS system is the best RMR mounting solution I have experienced."
Thank you, Craig
