"Technology" has no pros and cons except as it delivers a suitable gun.
Old fashioned heavy steel 1911s win at IDPA, "modern" light plastic Glocks win at IDPA.
There are others reasonably suitable and you can debate the pros and cons endlessly while you should be practicing.
I don't know what other type of target shooting you are talking about. I would rather have the 1911 than the Glock for NRA 50 yard slowfire, for example.
