I am a novice when it comes to 1911's. My Kimber has a FLGR and my new Premier II has a standard which I never knew existed till I purchased my LB. I am toying with the idea of purchasing a Baer stainless FLGR and plug. Please educate the pros/cons of this part. Also, does the FLGR use the identical springs as does the standard guide rod. Thanks.
