The chances I will need to defend a stage coach from Indian attack are low, but never zero. Accordingly, I wonder if it would be prudent for me to own a 20"-barrel Model 1892 in .45 LC. Now manufactured by FN Herstal (Belgium). It could use the same cartridges as my New Vaquero and could perhaps also use the high-pressure loads my pistol cannot use. Some readings seem to suggest this new 1892 can handle ridiculous pressures. Educate me Jeff, and also offer your personal assessment and recommendations.
For extra credit, speak to me O Wise One of loads and pressures for my New Vaquero and my Springfield Armory tactical 1911. The data I am seeing for these is ambiguous. I am pretty sure the single-action can handle the Buffalo Bore 255-gr, 566 lb/ft "Keith," and perhaps it can handle anything that will physically fit into the cylinder, but the pressures I see people spouting are inconsistent. Not that ballistics forums could possibly contain erroneous advice.
And finally, those forums also seem to suggest the 1911 might handle slightly higher pressures than the New Vaquero. I find some of this surprising in addition to confusing.
