mil-spec springfield upgrade
Posted: Tue Feb 15, 2011 8:13 pm
I fially decided to put a new barell bushing on my springfield mil-spec 1911 45acp. previously I had put a solid trigger with overtravel stop (c&s) , an extended thumb (swenson I think), and houge wraparound grips. I ordered a national match "semi drop in" bushing from midway on thursday and it came to my door this afternoon. I took some measurements with my calipers and found the ne bushing to be just a tad bigger outside and smaller inside than the stock one.
It fit nicely on the barrell, snug but not too tight. and fit snugly in the slide. just tight enough to turn without a bushing wrench. I oiled it up and tested the slide. it moved without binding, and noticeably tighter.
took it to the range and ran a couple magazines through to check for function and accuracy. function was good and the gun grouped tighter than it ever has.
the first 16 rounds at 25 yards from sandbags. (don't mind the little holes I was zeroing a red dot on a .223)
I then went over to a shorter range and a nice gentleman let me put holes in his 5 yard target the first 7 rounds made a 3/4" hole the next 7 rounds went in the same 3/4" hole with one flier an inch high......I think the accuracy was greatly improved.
