Gunsmithing colt 1911 slimline grip screws

[prodigalson]

So I ordered new VZ grips for my colt new agent. As I went to put them on, I noticed the factory grip screws' heads were too big. (5/16" and need to be 1/4") I go to my local smith and he sells me screws that fit the grips. I put them in and what do you know, they're too long. Ugh. The threads on them are 1/4" long and I need to file them down about 2mm. Would you all recommend filing them, or taking them to a grinder, or what? Please help.

Grinding is going to be quicker than filing.

You need to change the grip screw bushings also.

As TS stated. Slim line grips have different screws, bushing and bushing driver bit. Don't forget the red loctite when install the new bushings.
