If you hate using a paper clip to break down your bull-barreled Rock Island Armory 1911, then this video might be of assistance to you.
My 9mm Tactical II (non-railed 9mm 1911) is bull-barreled and requires a paper clip when field stripping the gun (per the operator manual). My 22TCM Ultra does not, and it comes with a 9mm barrel (not a bull barrel, though).
I’ve not tried the method in the video yet, but using the paper clip isn’t a huge deal for me.
