I recently received 2 scythian extended mag releases from Jim over at zero tolerence products. they were very easy to install it bolts on to the original mag release and moves it back to right in front of the trigger guard so it can be reached easier. i give them an a+ on their design/ease of installation, an a+ on price they are only 19.99, and a+ on customer service. he even sent me free bump bands with it, Jim is one of the nicest people ive ever dealt with. bottom line is it does exactly what its suppose to do.
