I recently saw an old article about 1911's made by the late Armand Swenson. I know that he has very good reputation in the US as one of the finest gunsmiths during his time. I read also in some other articles that one of his most common modification to a 1911 is the use of Smith & Wesson K38 adjustable revolver sights. I have been using revolvers for a long time now, and revolver sights are very good for defensive use. My S&W M51 .22 Magnum's black front sight is easy to see even in very low light. You just cant miss those big front sights. I am now also planning to install those same kind of sights with my 1911 Norinco Commander.I want revolver adjustables because I want the best of both worlds, Large front sight for defense. Adjustable rear for competition and accuracy work. Is there anybody who knows of this kind of modification in a 1911? And does anybody know what gunstores has them in stock?
