Bill - I think you are right on not recommending LRN for 9. I had seating depth trouble with MBC in an XD. I personally like the TC but is SWC really 'better' for tight chambers & normal bbl? I don't think the Glocks have a tapered chamber but the XD line sure does (~ 0.010", base to mouth). I think I'm like KAS, going to let the case swage the base down leave the larger nose to fit the bore. Fortunately the Xtreme LRN I have give a nice 0.01 step on the front band, for chambering tests.
