teuthis, no offense taken. Everyone has the right to his/her opinion, for which I served and defended, albeit a long time ago. That being said, a little history. I purchased a Mark III some time ago, as a target pistol. The trigger pull was exceptable but, after some research and firing a friends Mark III, I realized there was something better out there. Again, when the Mark IV came out, I "felt"was an advancement over the Mark III. I put 150-300 rounds through it and "felt" the trigger pull needed some work. My past experience with the Mark III led me to believe the trigger rework would be worth the effort. Much to my surprise, the job did not produce the desired result, YET. Now my shop has the Mark IV and is in the process of "fixing" the issue. Again teuthis, no offense taken and I hope you understand my reasoning now that I have explained it more thoroughly.
