Took my recently-acquired 1100 out to function and pattern test. I haven't decided whether to call it "The Dictator" (as it looks like something captured from a despot's palace) or "Elvis" (it's glitzy, showy and an American classic).
I've had several personally owned and agency issued 1100's and 1187P's. I owned a cut-down 18" 1100 since @ '92, and my initial LE agency was carrying 20" 1100's when I started in '93 before switching to 18" 1187P's in the late 90's. When I transferred to the State circa '08, I was issued a 14" 1187P until my retirement from full-time in 2018, and owned a personal 18" model for a while.
All that to say...the 1100's were finicky on ammo selection. None would function with anything under @ 1350fps. My agency issued 2 3/4" Magnum loads for duty...which made for a miserable officer-survival course I attended where we shot 100 rounds of shotgun one morning with agency supplied ammo and academy supplied 870's with rigid plastic buttplates. The 1187's were about the same...they would sometimes function with reduced recoil Federal 00 (1145fps), but not enough to consider them reliable with it.
With all that in mind, I ordered @100 rounds of Federal Power Shok 00 (1345 fps) to run through it (couldn't find any full-power LE FC). I also ordered @ 50 rounds of Federal 127LE full-power slugs (1600 fps). I have a sizable stash of 132LE 9 pellet low-recoil (1145fps) and 127LE reduced recoil slugs (1300 fps) on hand that I feed all my other guns (the 1301 will eat anything) and wanted to see if it would cycle any of those.
I was pleasantly surprised to find that this particular 1100 fed all the reduced recoil rounds with no issues. I put @ 200 rounds through it yesterday and it continued to eat and spit everything out like a champ despite being filthy at the end. I'm assuming that whoever did the barrel trim and Cerakote must have also opened up the gas ports accordingly.
Slugs off-hand @ 50 yds. The full-power 127LE's were printing just a tad low...the reduced-recoil slugs pulling left was my fault.
