Possible trigger upgrades for the Rock Island Ultra full size HC 10mm

[Kenk]

Not that the trigger on my Rock Ultra is bad by any stretch, but if I decided to upgrade to a nicer trigger, who might offer one for that particular model?
Thanks

Standard 1911 rules apply.  There are gonna be LOTS of options.  Getting better than the factory pull is gonna be a challenge if your Rock is like mine.

CHanging the trigger isn't gonna change the break really.  That will be changed by dealing with the sear, trigger, disconnecter and sear spring.  a different trigger face is going to give a different feel.  Long, short, flat curved, grooved, smooth are all differences that can be mixed/matched.

Thanks sqlbullet, that's along the same lines I was thinking about

A little late to this thread, but I will post anyway.  I got two sets of the Harrison True Radius ignition kits.  One for my Rock Tactical 45 acp and one for my Springfield Mil Spec 45 acp. Both went in without "fitting", though technically they probably should have been fitted.  The Springfield got a very nice trigger pull, straight out of the box.  However, the Rock had some issues.  The sear wouldn't go into the sear cutout in the frame, until it was narrowed a bit. Apparently the sear cutout in the frame is not square, or wide enough.  Once it went in, everything worked as it should.  However, it's trigger pull is not as nice as that on the Springfield, so it probably requires some fitting.

Interesting. I recently put a true radius sear and C&S leaf spring in one of my Colt 1911s. It made a noticeable difference. I was considering putting the ignition kits in my Ultra FS HC.

I have yet to detail strip it so I haven't started on that journey yet.

Really late to the conversation but I'll throw in my .02
IIRC, the RIA high cap uses the same trigger as the Para wide body.  I had great success with the Gun Craft trigger https://www.brownells.com/handgun-parts/trigger-group-parts/trigger-parts/triggers/para-ordnance-aluminum-triggers-prod6822.aspx?psize=48&avs%7cMake_3=Para-Ordnance in quite a few Paras and even an old Springfield high cap and a Bull.  (WILL REQUIRE FITTING)
If you want a Poly or flat face trigger, it is possible to make an STI https://www.shootersconnectionstore.com/STI-Trigger-2011--P845.aspx trigger work but it takes a LOT of fitting of the trigger bow.

If your looking to improve the trigger feel, any good 1911 smith should be able to polish the factory parts up to give you about a 4.5 lb pull that's fairly crisp and will last a good long time for around $100 or so.  Anything nicer than that an you have to replace the fire control group with something better.  The a fore mentioned C&S kit is my favorite and worth every penny.  They claim drop in but in my experience, some minor fitting is still involved.
