Well I started Glocking with a pair of 21's as I am a .45 person. I have been raised on and carry custom Colt/1911 clones. I chose Glock because of the durability,reliabilty,etc. Well on the 21's I did not like the trigger pull, so I sold them. I just bought a G-23 to start tinkering with. As I have never modded a Glock, what can I do to improve the trigger. I have read about spring cutting/replacement, guide rods,etc. How hard is it to change connectors etc. Any advise would be great. Thanks in advance for your help.
