Read that some folks, especially in 10 round magazines, use a 185 grain bullet to reduce the weight total that the mag spring has to push (elevate). The theory was that with less weight to elevate, the next round is presented quicker, thus an extra measure of reliability. Sounds interesting. I have never used a 10 round mag in my 1911. Just wondering about thoughts on the matter. Inquiring mind wants to know! Thanks in advance.
