About a year ago, I picked up this neat (and quite cheap) HR 622 DA/SA revolver. It shoots great. Heavy DA trigger, but crisp and nice SA.
There is one issue with it, and I've heard varous reasons for it. From the picture, you can see that when the hammer is down, the spur is directly in the way of the sights. You actually need to have the hammer about 3/4 of the way back before the sights are in view. I heard that HR went through some financial issues and reorganizations, and that they had a habit of using old parts on new firearms, and sometimes you ended up with ugly ducklings like this.
In any case, I'm hoping to find a way to modify it so the sights will be useful for DA mode. I need the spur to be about 1mm lower than it currently is.
I read that some old Colts had a similar issue, and that Colt simply put a groove through the middle of the hammer to expose the sights. Another thing I thought was to carefully "heat and beat" the spur to bring it down a hair. Or, probably best, but also probably most difficult, cut the spur off and TIG weld it back at a slightly lower position.
Here's my real problem. If I could find a spare hammer, I would buy it, do the mod, and swap them. I checked every gun part place I could think of (Numrich, Brownells...), and 2 HR forums. Nobody has a hammer available for this revolver. I'm concerned about modifying the existing one. If I mess it up, there will be no fixing it.
So, I have 2 options. I can either modify this hammer/spur to make it work with DA. Or, I can ignore it, and just run the revolver in SA mode. I do not like that idea--I have a dedicated .22 SA in .22lr and .22WMR. I don't need another SA revolver.
Does anyone have a thought on this? I've been kicking around the idea of using my dremel tool with a small abrasive disk to cut a groove, and then some needle files to clean it up. It should not change the function of the revolver at all.
