I'm glad you RIA guys have had good luck with yours, I've only had experience with one, about 4 years ago, a friend bought one at the gun show, where one of our big distributors were selling them for 250.00 bucks, hard to go wrong at that price. He shot it and it did work with ball, but he was hitting 7 o'clock on the targets pretty low. He brought it to me for a trigger job, as the trigger was somewhere around 8 pounds, had to use my fish scale to measure it. The initial trigger job didn't work very well, normal procedures produced a 3 lb trigger that would not release after the slide was cycled, I reworked the disconnector, and went over my work twice. After that I installed a used Colt sear, disconnector and commander hammer, that I had worked over previously and voila, 3 lbs. At the range the pistol ran fine, and now shot to point of aim, due mainly to the lighter pull.
I think Para, S&W, Springfield Armory, Kimber and Sig all have great pistols in that price range with a lot of features. I do favor the Para LDA, what a usable trigger. My advice is to pick up one of these pistols for 700-800 bucks or less, and then you can afford magazines, a holster and some ammo to practice with. Get one with high visibility sights, night sights even, a beavertail grip safety, and go from there. The grip safety is not a deal breaker as they can be had pretty cheap, and even gunsmith installation is not or should not be very high. I charge 25 bucks labor for one I have to round the frame horns on.
Side note, Alan Smith of S&A magwells, grip safeties and such, taught me a good trick when fitting grip safeties, you put a notch in the top of the arm that presses the spring for the safety, so it clears the hammer pin, then you don't have to lower the mainspring housing to remove it. Cool tip.
