I just finished installing an Ed Brown Tactical Ambi Safety on my Ruger. It was a lot easier than I thought it would be. I watched a simple youtube video. I posted a link to the video I watched. There are bad videos out there. Be careful who you take advise from. This one shows a lot of detail. [ame]http://www.youtube.com/watch?v=bkYOn9S6ULg[/ame] I also installed a Wilson Combat magwell. It looked very cool. And it made loading a little faster with my Chip Mcormick and my Ruger mags a little faster. But there was a problem. My Act and my Mecgar mags will not work with the magwell. They are the ones with the hollow floor plates to add the 8th round. They are my most reliable mags. Some people like the Chips. But I have found that they nose dive too often. So I took the megwell off. I will put it back on when I find some different floor plates. The safety works flawlessly. I did test after test after test. I don't take chances with safeties. I though people might want to know about the magwell issues with the hollow floor plates.
