Have installed the Apex Duty Carry Trigger kit except for the striker block and spring.
Have not been able to remove the rear sight. After several attempts of trying to punch it out, I took it to a local gunsmith and he tried with a sight removal tool and was unable to budge it. He then tried an arbor press and still couldn't get it to budge. He says the only alternative is to mill it out and replace with a new rear sight.
Has anybody else experienced this difficulty and found a better solution?
