Hey a1dookie,
I have the correct tools to replace both front and rear sights on a Glock. With the F&R tool kit it's very easy to change out the sights.
I live close to Hamilton and I'm a member at Silverdale. As mentioned by Blaxsun, the kit could be mailed back and forth to you, at your cost.
Or if you want to take a drive Hamilton way you could change out the sights and head back home. Only cost would be fuel.
Again as mentioned, as you only need to bring your slide to do the change out, there will be no issues with permits, etc.
PM if you are interested.
