I make no claims to being the worlds greatest pistol shooter, but have been an active pistol competitor in various events for the last 47 years. I am currently active in IDPA, PPC and IHMSA.
I purchased my first Glock (M-23) about 4 years ago for CCDW when it was approved here in Kentucky.
My personal opnions about triggers is if you want a target gun ( I have a Clark Long Heavy Slide and an accurized Colt NM)get yoursel a 1911 and have it accurized by some one like Les Bauer or Clark Custom guns. (Both of mine were done by Jim Clark himself before we lost this great shooter and person)You will have the best of all worlds for target shooting.
If you want a firearm for personal protection, particulary for concealed carry, get yourself a Glock of some kind, go to a training camp such as Rangemaster in Memphis, OPS Southeast and learn to use the Glock System. Don't mess with anything on the Glock.... That way you are much less likely to wind up in a libility suit for an accidental discharge, or injureing yourself because of a tricked up trigger.
If your primary interest is target shooting and you don't intend to carry a firearm concealed, GET YOURSELF A 1911.... either Colt, Kimber, or one of the custom guns I mentioned. If you get a Springfield, be prepared to have it accurized. Some of them come out great, but they have more than their share of lemonds.
What ever you decide, get lots of ammo, get involved in a shooting activity, join a gun club, and "JOIN THE NRA."
Good Luck
