  1. Not sure if this helps much since its not coated bullet data.  But last weekend I put together a few FMJs with sport pistol to just to see what I would get. Im almost ashamed to admit they were fired out of a S&W Sigma with a 4" barrel. Its my red headed step child of load testing guns. 

     

    180gr Armscor FMJ 

    Mixed Brass   CCI 500 Primer

    1.125 OAL

    4.2gr Sport Pistol

    High 815fps  PF146

    Low 797fps PF143

     

  2. These loads were shot out of a stock G20 Gen4. But they might help. Neither of these loads were a max charge weight so there should still be a little more room to bump the charge up. 

    135gn Nosler JHP    10.9gn Power Pistol    Avg: 1441fps

    135gn Nosler JHP    12.8gn AA7                   Avg: 1322fps

    Ok cool I might try that. Stupid question but how did you pop the base plates off? I cant figure out how to do it without using a tool and possibly damaging magazine body.....

    I didnt remove them. I just did a little sanding with them still attached to the magazine body. 

  4. I had the same issue with those mags. The plastic baseplate is a bit wider than the factory metal one. 

     

    The solution was to sand down the sides of the baseplate until the mag seated easily. You dont need to do anything to the front or rear of the baseplate...just the sides.  If I remember correctly it was something like .020 that I had to remove from each side. 

     

    You should still do a quick measurement of the width of the stock metal pad vs. the plastic ones to confirm how much material to remove. Measure, sand, test fit...repeat.
