So I've gotten my RIA pro match ultra in .40, ordered my mags and holster, and now I'm looking at parts I want to upgrade. Sights are going to be a must as I want to swap over to night sights. I believe these are novak style sights but anyone here know the measurements or how to take them? I've already ordered an extended slide stop and a 13lb recoil spring from wilson combat. What I'm really curious about is the sear, disconnector, firing pin, and safety. From wilson combat most of these parts are listed either for .45 or 9mm/.38, but no options for .40 so I'm not sure which to order. Currently in my cart is the deluxe bulletproof sear A-2 (item 314), bulletproof disconnector (item 573), and the wide competition lever thumb safety (item 6B). From my understanding most parts for a 1911 are going to require some hand fitting/tuning but I'm not sure what caliber to even order for, or if there's another site that's better suited to ordering parts for this gun from.

I have one of the RIA Pro Match Ultra 40 HC pistols and the rear sight is an LPA cut.  I have this sight: https://dawsonprecision.com/dawson-precision-lpa-cut-adjustable-black-rear-sight/

 

The front sight is a Novak cut.  I have this sight: https://dawsonprecision.com/novak-cut-fiber-optic-front-sights/  (0.180" tall x 0.100" wide Patridge Serrated)

 

The sear, disco, and safety are standard 9/38/40 parts for 1911s... or at least I've never found any problems with any of several replacements from various companies that I've tried.

 

I don't recall exactly which firing pin it uses as, even within 9/38/40, firing pins aren't the same.  I believe this EGW firing pin works in all of my 1911s and Rock Island wide-body 1911s, though: https://www.egwguns.com/o-s-firing-pin-1911-068 

 

Thumb safeties are sometimes drop-in and sometimes require some fitting.  I've been lucky and was able to replace the Rock Island thumb safety with a Sig Sauer thumb safety that required no fitting: https://www.midwestgunworks.com/page/mgwi/prod/SAFETY-AMBI-1  (Please note that I prefer minimalistic thumb safeties)

 

Most 1911 parts require some degree of hand fitting, it's not just Rock Island pistols ;)

Thank you so much for all the information! Time to go through and place some orders. Would you actually recommend an extended firing pin? I'm not even sure if they are extended but I'm assuming that's why folks suggest replacing them. I know it's commonly done on CZ's to add reliability. No idea how well a stock RIA firing pin holds up compared to aftermarket offerings. the sear, hammer, and disconnector I've heard all wear fairly fast and should be replaced soon.

Extended firing pin is 100% a must. The stock one will bend. As for the trigger parts, replace them ASAP. I ran one for about 2 years and loved it. Ran 200gn 40 cal blues almost exclusively for about 30k rounds. Lightened slide, internal work, set up for 2011 STI mags ect... if you decide to get trigger parts do get the extended EGW sear as the hammer/sear holes aren't always perfectly placed. For thumb safety you can keep the stock ones for a long time if you like them. They are the style that the right side paddle is held in with the sear pin. Also if you decide to replace them with other style ambi safetys you HAVE to get ones that the right side paddle is held in with the sear pin as the frame has no cut out for the tang on the cheaper style ambi safetys. They could be made to work but require cutting a slot in the frame. I ran that stock ones for about 15k before I swapped to EGW HD ones and they hadn't broke yet but were getting loose. The one pictured was mine. I sold it this winter because we built me a 2011. It was a lot of fun to shoot though.

What holster did you end up using? I've tried the holsters from blade tech for the sti edge and no luck.

I ran one for an STI Edge from GX for a while. Then switched to the DAA Alpha X with the STI insert. Gun was a little loose in the holster but still 100% secure. It didnt move side to side but could tilt.
