The 1187 has a gas compensating system, supposed to use all available gas for light loads, then bleed off unneeded gas with heavy loads. JMO, it doesn't work, and I know 10 people will say theirs has been 45,000 rounds without a problem :roll: :roll:
I've probably been around 100 or so 1187's on Sporting ranges, one was the prettiest gun I have ever seen, but it failed to cycle so much it was put up and shot someone elses gun to finish. None of them------none, did not have issues with cycling some rounds. Clean/dirty or inbetween, I think the system needs work.
The 1100 is simpler, gas ports to the piston, no compensating device----once you learn what loads it will cycle and how to care for it, you know what your limitations are----and would be my choice of the two.
Next to the SuperX-1 Winchester, they are the lightest recoiling guns out there, but the SX hasn't been made in 25 years. :roll:
