No double spring?That’s pretty awesome.
Just this week I was talking with one of my HRT buddies about 1911’s and the growing pains they had in the early days of the Springfield. Apparently, barrels were rupturing under the copious diet of 230gr +P stuff we feed them. So, they were almost all modified to ramped barrels.

Really like the dual spring on the M45A1 but might only be the “feeling” in difference of shooting more Commander than full size.
