Nope.
And it will help with getting the magazine seated fully during a quick change out.
Nothing worse than pulling the trigger and the magazine falls out cause it wasn't seated fully.
I have literally
never had that problem...dozens of IDPA matches and several training courses, not once, ever...
If you train properly, consistency is a key element--changing something small can make all the difference in the world, but that difference can go either way...
If you are having trouble seating a full mag under stress, give it a try! If you are simply believing internet mythology about magazine springs then I would say more research is in order--reducing your weapons' capacity because of such foolishness is not advisable...
Physics tells us that the magazine spring, when compressed or uncompressed--during loading and unloading--is when the force is applied and removed from the spring, which causes friction and wears out the spring tension...
I replace magazine springs every 3 years...its a routine maintenance thing since I shoot a lot...I leave all my magazines loaded 95% of the time and have yet to prematurely wear out a spring...on any of my 11 magazines for my XD or the 8 for my HKs I previously owned...
