New Glock magazines can be stiff to load initially; leaving the magazine loaded minus the final round for a short period or cycling it from full to empty several times can help seat the spring and ease loading. The polymer-encased steel insert protects the body from impact and maintains fit and function under normal use conditions. As a factory part, this magazine provides original Glock fit and form for owners seeking factory-compatible magazines for G21/G41 pistols.
