Did you even read the rest of the post?
Read the whole thing.
See above: too much emotion, not enough logic!
Resorting to personal attacks is verboten here. Tone it down please.
You want logic? Here's my logic: The below 1911s were all switched to GI style short guide rods & spring caps if not so equipped from the factory, but otherwise they were unmodified unless noted.
SA GI - Ran anything I fed it.
SIG GSR - Only thing it would run was 185 gr LSWC - wouldn't even run 230 gr ball.
Colt XSE LW Commander - 80 Series FP block broke, but it ran fine one I took all the 80 series crap out.
SA Loaded base parkerized - ran anything I fed it.
Kimber pre-Series II - ran everything I fed it.
DW RZ-10 - Ran everything I fed it.
SA full size LW Operator - even with the ramped bbl it ran anything I fed it.
Colt Delta Elite - preemptively converted to non 80 series, converted to single recoil spring with heavy main spring and oversize FP stop to deal with 10mm recoil better than the over sprung dual recoil spring setup, per Tuner and BBBill's recommendation - ran everything I fed it.
Newest is a Colt Wiley Clapp 21st Century commander. In less than a week it's run 200 rounds of 230 ball ammo of various manufacture, 50 rounds of Federal HST 230 gr +P, and 16 rounds of 230 gr Speer Gold Dot. I've done nothing to it other than clean and lube after unboxing, and clean & lube after a couple of range trips.
Notice that the "Improved" guns were the ones that had problems. The pistols that were/are internally closest to GI spec ran/run best, and the XSE converted back to get it nearly GI spec internally had no problems thereafter; and the SIG GSR, which was a supposedly "improved" 1911, and deviated furthest from the GI spec, was the one with the most problems.
