Just my opinion but for a general plinker witout all the frills a SA Mil Spec is a great place to start and easy to upgrade as time goes on.
Now understanding that these are like AR and too easily modified, improved here and there, this and that added....You might want to save a little time, money and after market parts and just jump in at the SA Loaded Level and get a few of the basic frills you will most likely want in say a year or so.
Trust me, the idea of a box stock 1911 pistol is a pipe dream, it just doesn't happen.
For the money IMHO is a TRP that may never need to be upgraded with anything but is about $500.00 more than a Loaded.......Is is worth it, maybe not to some, well worth it to others and then there are the Pro Owners that cut their teeth on a TRP as a starter 1911.
Myself, I have a SS TRP, TRP Operator and a SA Lwt Compact and could be happier with all of them.
Note, all 1911's DO Have Grip Safeties.........Mil Spec has a regular GI style where the Loaded and better come with what is called a Beaver Tail.
The Beaver Tail for the most part have elongated thumb gaurd as well as a Memory nub to make sure it is depessed completely.
