A question. I have a 4.2" RH .45 Colt I plan to use 325-335 grn. bullets at 1200 fps + in in bear country (MT and Northern ID). I know Bowen makes a sight blank 0.060" taller than stock. Do you find that you need this height or less works ok? This is not for hunting but more as protection at closer ranges when out and about in the woods.
