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