My latest acquisition is a used PCC. I changed to a custom magwell

I see some have upgraded to Mcarbo parts. Are there parts that make a bigger difference or is it smart to just get the whole upgrade package?
I am new to Ruger firearms.

I love the Mcarbo flat trigger on my P365 XL

I managed to get a Ruger PCC this past winter. I decided to use it in USPSA a bit. So, to make it easier,, I switched over to the Glock magazine adapter, added a flared magwell insert, & added the oversized mag release. Topped it off with a Burris red dot,, and I've been playing with it a bit.
I'm never going to be good enough to spend a lot on stuff like triggers & such. I just do it for fun!
(PS: Last weekend, I shot the USPSA Classifier "Bang & Clang" in 3.94 seconds, clean.)
