Wouldn't the 1911 have a thinner profile since it doesn't have a double stack magazine? If so, that would be a big plus.
Don't the sprinfield compacts already come nicely bevelled? I've been doing a price comparison between the wwII milspec and the Springer loaded model- I ended up ordering the loaded model since the upgrades between the two would actually costs hundreds more than the price difference.
Never liked ugly square guns, in my highly biased opinion, get the 1911.
