Same here... lots of love for the TRP
I've done quite a bit of modifications/hand filing on my stainless version - here's a after/before shot:
Very reliable, accurate, and absolutely love the 20lpi front strap checkering. With all the work I've done to mine, feels like a completely different gun, but they are awesome.
Edit: I think the carbon steel and stainless base TRP's can be had used for around or maybe even under $1k. If I'm not mistaken, Springfield honors transferred warranties as well (lifetime).
