I have had a Springfield Loaded model 1911 since about 2013/14. Love the pistol, will absolutely never sell it. Only pistol i currently have
Only downside is the ejectors are not pinned, and there is in fact no hole drilled to install a pin.
Has had absolutely zero malfunctions with its factory supplied magazines, a kimber stainless 8rd, and a Wilson combat extended plus power 7rd magazine. The only issues i have ever had with the gun, where with a colt brand magazine (7rd) i ordered from midway. That magazine is now a range only mag, even though it has seemed to work itself out.
There are a few different styles of 1911s and magazines to go with them
1. Standard goverment/commander grip size (these will usually be 7 or 8rd, though extended 10, 15, 25, etc are available)
2. Officers 1911 Grip (usually 6rd capacity in .45acp, i am not sure if the Colt defender uses Officer magazines or not)
3. Double stack 1911 (there are Full size Paras, and compact paras, and i am not sure if the Caspian or STI double stack frames utilize para magazines)
4. Springfield EMP (only available in 9x19mm or .40 S&W)
There are also several calibers available in double stack and single stack guns (10mm, .45ACP, .40S&W, .38 Colt super auto, 9x19mm, etc)
The Loaded model is a fantastic gun though, it should be accurate and reliable for you. I chose to swap a few parts, as i did not like the two piece FLGR, nor the long aluminum trigger, nor the ambi safety, etc
When unholstering and preparing to fire, the safety should be disengaged with the thumb of your primary hand
