Your .460 Rowland® Extra Power Magazine Spring is suitable for use with all standard 13-round Glock 21 and Glock 41 Magazines.

Stock magazine springs offer low positive feeding, even when new. While adequate when using low power .45 ACP ammunition, these springs frequently become fatigued and over-compressed when used frequently or left compacted under a fully loaded magazine.

At that point, they will no longer feed .45 Super or.460 Rowland® ammunition reliably.

The most common problem tends to be  “Nose-Down-In-The-Magazine-Failure-To-Feed”, AKA “Limp Wrist Syndrome”.

Firm up your grip and use your .460 Rowland® magazine spring to ensure more positive and reliable feeding through your .460 Rowland® Magnum Powered semi-automatic pistol.
