Hello, Glock Talk. I recently bought a G23, gen 4 and am considering purchasing a TLR-1S. I was surprised to see the issue of feeding malfunctions related to tactical light use. Does anyone have any experience with this issue? It might be a deal breaker for me. Thanks for the read. http://www.streamlight.com/documents/issues/GlockIssues.pdf Wanna kill these ads? We can help!
