JupiterAdam Posted May 27, 2015 Share Posted May 27, 2015 Has anyone experienced a failure of the magazine release? During the make ready command, my M&P Pro 40 would not retain a magazine - it just slid out repeatedly. Upon removal of the Costa Catalyst extended magazine release, the reason was clear - the tab which retains the magazine had worn off completely (after 1.5 years and 3000 rounds). I would like to hear of any similar experiences with the plastic Costa Catalyst - in order to determine if this is typical wear or unexpected failure. I would also like to hear if anyone has had issues/failures with the metal extended magazine release made by LF Arms. Thanks in advance, Adam.

Domineaux Posted May 27, 2015 Share Posted May 27, 2015 I use the LF Arms version and it has been perfect the past 2 years and 6k rounds. Link to comment Share on other sites More sharing options...
CPW1265 Posted May 27, 2015 Share Posted May 27, 2015 I have had the catalyst in my 9L for 3 years and over 10k rds with no issues. It does require a drop of oil every now and then so that it's smooth. Link to comment Share on other sites More sharing options...
StealthyBlagga Posted May 27, 2015 Share Posted May 27, 2015 I use the LF Arms version and it has been perfect the past 2 years and 6k rounds. +1. With this part inexpensive and available, I am not sure why you would mess with anything else. Link to comment Share on other sites More sharing options...
JupiterAdam Posted May 27, 2015 Author Share Posted May 27, 2015 Domineaux and CPW1265, Thanks for the response. Would you mind pulling your mag release out and reporting back on any wear (the tab on mine was completely eaten away). Although I am likely to go with the metal version, I am interested in hearing on how other releases have wore over time and use. Thanks, Adam.

Domineaux Posted May 27, 2015 Share Posted May 27, 2015 (edited) Just checked and mine (LF Arms extended) looks like new. Edited May 27, 2015 by Domineaux Link to comment Share on other sites More sharing options...
rack&roll Posted May 27, 2015 Share Posted May 27, 2015 My M&P Pro .40 started dumping mags after only about 6 months of use with the factory part. Same problem...mag tab worn on mag release. I had to order an od green one from SSS because all of the black ones were sold out. My 9L is much older, and no problems. Link to comment Share on other sites More sharing options...
JupiterAdam Posted June 18, 2015 Author Share Posted June 18, 2015 I just wanted to give a shout out to the guys at 21st Century Gunfighter. They replaced my broken magazine release without any hassle or cost. I always appreciate a company that stands behind their products. Link to comment Share on other sites More sharing options...
misterkhan Posted June 20, 2015 Share Posted June 20, 2015 I had the opposite problem: the mag wouldn't fall out. The release was a bit too long and would drag on the mag. Link to comment Share on other sites More sharing options...
