I am always reluctant to recommend Glocks to new gun owners. That safety on the trigger is not much of a safety until you learn to keep your finger off the trigger until ready to fire. I have a G19 and it is very reliable. It is just the light trigger pull and where the safety is located that makes me reluctant to recommend it. A 357 magnum can be loaded with 48 special for lower recoil so that could be an interesting option.
good point, the training and repetition of the rules must always be adhered to...
