Number your mags with a marker or scribe.T1911B said:Unfortunately I did not pay attention to which one of the mags <or both> were having the problem. I will pay more attention next time and see if it favors a mag or does it with both. If I decide to replace the slide stop can I use a slide stop from any brand (are they all interchangable)? Thanks for the info!
