I'm considering replacing the sights on my M&P Pro 9 5" and my MP22. My main focus is shooting them for Steel Challenge matches, but I also do occasional plinking/shooting for bragging rights with friends at local indoor ranges. I want to have the same sight picture on both, both for consistently in shooting them one after the other in matches and for having the the training with MP22 apply a a bit better to the M&P Pro. After a fair amount of investigation, I have decided to go with Williams Fire Sights with green in the front and red in the rear. My only decision left is whether I should put on fixed sights or adjustable ones. I'm currently using a Revolution holster, which looks to have plenty of clearance for the adjustables. Has anyone else gone through this decision before and tried both? If so, do you have any wisdom to share from that experience?
