I recently bought a used S&W M&P 9mm Compact from a private seller. Somewhere along the line of his ownership of this gun, he had lost the magazine loader. My question is, Is there a specific brand of magazine loader that I need to buy or will any 9mm magazine loader work? I looked at the Uplula magazine loader at my local sporting goods store but on the back of the package it didn't have the particular S&W M&P model number. It had other S&W models but not the M&P 9mm. Any feedback or help would be appreciated, Thanks👍
