Yes. But I have the B model. Check the primer slide to make sure it has no nicks or burrs. If both sides of it are dead flat, you might mic it to see that it is not tapered. If everything checks out ok, you might need to file in a tiny bit of clearance so that when everything in cinched down the slide moves easily. (Of course before you do anything, make sure everything is clean.)

My slide would jam now and then with both screws hand tight. I got tired of fiddling with the screws and filed in a tiny bit more clearance and haven’t had any more trouble. If you’re not sure what is going on, you can mark the surfaces with a sharpie or something like that and look for the interference.

If you’re leery of filing, call Dillon and they will probably send a different slide. They’ve always been great about helping when I’ve called them about problems, which has only been a time or two.
