Fits perfectly in my tisas 1911 - Ed Brown Products 1911 Magazine Release & Button

Just want to share the good news for anyone that might also want a simple upgrade to their lower cost 1911, I'm new to this series of handgun. One of the first upgrades I had to do with mine was change out the short mag-release to this one. It is a super easy install, 0 fitting, and it works great.

Also would suggest a little Blue loctite on the threads that hold the extended button onto the release after you get yours installed, just a dab will do.
