SIGcurious Posted May 20, 2023 Share Posted May 20, 2023 For the life of me I can't get my SDM sight to install on my 627. Anyone know a trick that I'm missing? I've installed other DX sights, but this one seems impossible. I think because of the length of the actual sight. My fingers are tore up! Link to comment Share on other sites More sharing options...
ysrracer Posted May 21, 2023 Share Posted May 21, 2023 I had to fit mine. A few minutes on a wet stone. Link to comment Share on other sites More sharing options...
Carmoney Posted June 6, 2023 Share Posted June 6, 2023 Typical. I always knock off the sharp corners on the base of the sight with a file until it finally pops into place. The other option is to drive out the retaining pin and remove the spring and plunger, install the sight and hold it in place and reassemble.

10mmdave Posted June 6, 2023 Share Posted June 6, 2023 I had the same problem, took my Brownells .055 front sight pin punch and pushed the plunger in as far as it would go, drop the sight in and retract the punch and it seated like it's supposed to, worked for a couple of hard sights. Another thing I also started using was a small machinist vise, about an inch-inch and a half wide, tape the jaws and clamp the sight in the vice, gives you some more meat to hand on to and work the sight blade. You need to leave enough room on the sight to rock the vice & sight into the groove. Link to comment Share on other sites More sharing options...
