Hi guys, I picked up a Colt MK IV Series 70 in 9mm from my gunsmith. http://www.abload.de/gallery.php?key=jDMQ5OI2 Since this is a target pistol for me, I want to install a new set of sights, or better have them installed. The front sight is the mil spec bump, that I just can`t really see on the 25m target distance. If I point it out correctly, it is staked in the slide, similar to the CZ75 Pre "B" front sight. At midway, here in germany, I have seen sight combos including a new front sight. In example, this one: http://www.midwaydeutschland.com/apps/eproductpage.exe/showproduct?SaleItemID=511942 My question is, will the fron sight stay snug in there, or do they have a tendancy to loosen up and fall out at some time. What is the best way to replace the front sight on the 1911 with the mil spec bump sight?
