Thanks for the info. on your 4596! I've had a somewhat different experience: My 4596 has served first as my duty weapon, then as my carry piece for about 20 years with virtually no failures, stoppages or problems, save for a crack recently discovered in the main body of the safety. (S & W promptly fixed that free of charge and in a big hurry). I am a big fan of the 1911 design, too, and I own two of them, but I continue to be astonished at the robustness and reliability of the 4596. I first posted here to find out whether the other owners of this limited production gun have had a similar experience. Cheers and have a safe and happy New Year!
