Bought mine a while back and first thing on the agenda after putting about 200 rounds through it was a trigger job with a new spring, polish the ramp, slide and side of the sear. got the pull down to about 4.5# without a hitch running about 500+P rounds through and not a single jam or stovepipe...
Couldn't have said it better myself! ~ Caveat emptor!
Use what you are comfortable using however, paying mind to RICK SR, go find a range and maybe rent a Shield (if you can find one) and blow a few hundred rounds through it then see if you still like it as much as your C. Maybe that will help...
