Not sure of that exact setup but I have found it's usually quite easy to improve magazine latching. Closely examine what is supposed to catch to latch the mag, look both at the "nub" on the mag and what's in the mag well that catches it. Don't file anything until you're sure it needs filing. The latch might need slight filing if the magazine nub isn't quite going over it. If it is going over it, don't file anything, try slightly prying the spring latch to make it stronger against the mag. If you do file the latch, think about the geometry, a slight angle on it may be right to improve how the latch mates with the mag
