I always heard that Golden Sabers were good for feeding 1911 and would be my choice if hst's proved unreliable or you didn't have at least 2 mags to blow through checking since they can hang up on some from what I have read and heard.
Do not use the Train and Protect I sent it to Gun Sam to test and did not expand.

185 or 230 golden sabers bonded now available, or maybe 185 plus P underwood Nosler if you like how it performed in Gun Sam's MDF testing...his MDF testing takes clear gel very very similar to 4 layer real gel results comparing all his hst gold dot and critical duty since he started that protocol . the 230+p nosler underwood didn't expand even from long glock barrel very strange.
