I've been eyeballing those flat firing pin stops for awhile. I see I can get the Lehigh bullets at Midway, a new firing pin stop will probably be coming with the bullets.
The only thing I will be missing is a dang chronograph... I saw Lehigh had a BC of .099 listed for the 120gr.... Maybe I will be doing some range drop calculations 
Firing 45 acp in the conversion kits is advertised as being safe but this SW1911TA has a quite large external extractor that must be getting in the way of proper chambering.
