I own both the Ruger SR1911 and an M&P .45 with 4.5" barrel and manual safety. The M&P is overall a superior weapon. Everyone should own a 1911 but I'd choose my M&P over any 1911, even a Brown, Baer or Wilson when the SHTF. About the only benefit of an entry level 1911 like the Ruger is the trigger. Step up to a custom or semi-custom 1911 and accuracy becomes another benefit. However, the M&P will keep banging ****** ammo in the dirtiest environments long after a 1911's extractor went limp. The M&P is more reliable, holds more rounds, is lighter, is more corrosion resistant, is safer (with manual safety), is easier to work on, has adjustable ergos with the different grip sizes and points as naturally as a 1911. It's trigger really isn't that bad. The take up is a little gritty as you pull through the firing pin safety but smooths over time and the sear breaks like glass despite being a little heavy. It's also accurate enough for 25 yard head shots off-hand. Get the M&P.
