James - the 1911 is pretty much the gold standard that all other triggers are compared to. The design of the trigger lets you pull straight back instead of any rotating angle like many guns, and even the cheapest 1911 trigger flat out rocks
I LOVE me my 1911 guns
My fav that I own is an STI Sentry in 45acp. All forged frame and slide, with tool steel internals. I'm drooling. LOL.
For the unsupported Glock 10mm comment, I considered a 10mm but decided against it. Instead, I bought a Gen 4 Glock 21 in 45ACP and then replaced the trigger (barf!) and rebarreled, re-sprung, and added the required compensator to make it run 460 Rowland. It kicks the crap out of any 10mm and doesn't cost me much more to load than when I load 45acp (uses the same dies too). My favorite load is a 185gr Nosler JHP running about 1500fps. It will also do the heavies, but I haven't played with any loads above 230gr. For heavy 45 I do Linebaugh loads for 45 Colt in my Ruger Bisley convertible
