Ive tried both mags now and i cant seem to get it full. When i get to a certin point i stop and dont try and force them in there. Ive tried 2 different brands of ammo also.
Ive taken the mags apart to see if there was any problems or anything inside them but i dont see any issues other then maybe the spring is to long?
I have the two factory shipped mags loaded with 18 rounds each. The 18th round required some effort but it fit as advertised. When at the range target shooting however I usually stop short of 18 rounds just to give the thumb a break.
If the last round goes in real hard I wouldn't bother with it and never laod another over capacity eyen if it will cram in there.The spring is designed to compress so far,overloading or forcing the spring to compress her will push it beyond it's elastic limit and weaken it.Cycling and overcpmpressing a spring is what wears them out,no sense in prematurely wasting one by trying to overload it.
