Well I won't say that it was easy but it is definitely possible. Be forewarned-you may reach a point in the process when you decide to take the pistol to a gunsmith so he can put it back together for you. I will try to post pictures later.
First the easy part. Take a 1/16" or 3/32" punch and hammer out the front grip pin-it doesn't take much force so go easy. The pin does not need to be hammered all the way out, just past the frame. WARNING-leave the rear grip pin alone! It holds the sear and the sear spring in place-hammer that out and you will be sorry (I know I was). After hammering out the pin it should be easy to lift the front of the frame off the grip. It will only rotate up a little because the rear of the frame is held in place by the trigger spring (not the grip pin). Once the frame is lifted up put something like a small allen wrench (anything with a curve) under the "u" of the mag release spring and lift it up. The Magazine release should now just slide out of the grip. If all you need to do is dremel the catch then you are home free-reassemble in the reverse order and you are done.
Now for the hard part. If you are a southpaw like me, and REALLY want the mag release on the right side of the frame, so you can release the magazine with your left thumb, your work is just starting. This part is going to require lifting the entire frame off the grip and reversing the magazine release spring. If you notice the magazine release bar has a hole in it's body within which the tip of the spring fits. The spring itself is longer on one end than the other so the only way to reverse the magazine bar is by reversing the spring as well. I could not figure out how this could be done without removing the frame from the grip.
Next get a bright light and shine it on to the back of the frame and study the relationship between the sear and the hammer-you will need to remember this for later.
Remove the cap from the bottom of the grip by prying it gently off with a small flat screwdriver. The trigger spring is held in place by a bar. Pull the bar towards the bottom of the grip with a curved tool (Allen wrench should work) and twist it to release the trigger spring. Now you can simply lift the frame off the grip. This will also expose the trigger bar, trigger spring, extractor, slide stop, slide stop spring, etc. Once the frame is off it will be very easy to pull the magazine spring all the way out and reverse it. Place the magazine release in it's new orientation, orient the hole to line up with the long arm of the spring and you should be good to go.
Reassembly is in the reverse order from above. The only tricky part is re-establishing the relationship between the hammer and the sear. After you remove the frame the sear spring will snap the sear to the back of the grip. To get the frame back into place the sear has to be rotated towards the front of the grip to allow the back of the frame to seat properly. I found the easiest way to do this was by using a long, small, flat screwdriver, which I placed through the middle of the frame, to hold the sear down while I moved the frame into place. The screwdriver acts as a guide in a way. You will know when it is right because it will "snap" into place.
I am not sure what this will do with regards to your warranty-so enter at your own risk.
