    I am interested in a "good" flat main spring housing for my Springfield Mil spec. Its purely a grip issue but if I am going to mess with it, I would like to at least replace the part with something better than oem. Can you suggest a good MSH and should I change anything else while messing with this specific area of the pistol ie.. spring or other associated stuff in the housing.

    Any of the common name brands would be good. The MSH doesn't do much...

    I replaced the MSH on my GI with one from Smith and Alexander (http://www.smithandalexander.com/spr-housing.html). Matched the park finish almost perfectly. Also the quality and fit are great.

    Also I am pretty sure you will have to get a new mainspring, cap, retainer pin, and cap pin.

    The Kimber polymer is top quality. Despite all the threads I've read about them cracking. Those people were just liars and haters

    I just swapped the MSH on my Mil Spec w/ a flat Springfield Mil Spec and I like it much more than the arched MSH. I actually posted on the WTB section of the 1911 forum that I was looking for a Springfield flat MSH. I kid you not that a very nice gentlemen sent me a Springfield parked serrated MSH w/ the internals for free. I couldn't believe it and I plan to pay it forward someday too.

    If you change the MSH you will need to change the internals as well to standard parts because of the ILS system. A new spring cap, retainer pin and 23lb mainspring is needed. The bottom wedge shaped pin can be re-used from the original. The stock Springfield MSHs have a hole for a retaining pin but niether my Mil-Spec nor my Loaded had one in it.

    Springfield on the left, normal on the right.

    ETA: They may look the same length when put together but the top cup type pin on the Springfield is deeper than standard which makes the overall length shorter.

    make note it is not always a drop in part I tried to replace the flat with an arched on my les baer but after replacement the hammer would not fully cock- just to let you know any part replacement on any 1911 is going to be a crap shoot as far as fit and function
