No, the Glock ODS sights are new.
I've yet to see them or shoot any Glock pistols with them.
Fox News did a article on the firm & it has a lot of + buzz. Unlike the new RIP 9x19mm rounds, but that's a different topic,
.
I'm not even aware if R4E uses steel or polymer for these Glock sights.
The product descriptions don't say.
For sales & ?s, Id look here;
www.r4evolutionstore.com .
The company may expand to other models like SIG, XD/XDm, Walther, Ruger, S&W M&P, etc later into 2014/2015.
