I’d like to do some light modifications to a blue series 80 govt, going towards the full size commander look like this: I know A smith could notch my current GI grip safety, but it would be easier to buy one and have it installed along with the hammer. Is this the grip safety I want that works with rowel hammers? https://www.gunpartscorp.com/products/723590 Having my GI grip safety swapped with a rat tail wouldn’t require refinishing etc like having a beavertail fitted, would it? I’m planning on grabbing the Wilson retro hammer, but I also have the option of an old kings gun works round hammer or this https://www.gunpartscorp.com/products/259910D Any feedback on which one to buy? Thanks. Once I gather all the parts I’ll be sending it to a smith.
