Hi fellas- I'm new to the sight......Just wondering if hardcast 200 gr SWC slugs will feed thru the M&P 45 o.k., or will the throat need some work done on it? I like the gun and am ready to buy one, but I shoot the 200 gr SWC cast exclusively in my 1911's and I don't want to have to load RN for the M&P. Thanks.
