I have a Springfield TRP as a "beater". The FL guide rod is in the trash can, and a EB GI plunger has been installed. I plan on one of two courses of action (in due time):
A) Sell it and buy another Les Bear.
B) Send it to Springfield's Custom Shop for replacement of all MIM parts.
Regardless if I keep the TRP in its factory guise, rebuilt by the CS, or sell it - I will have another Les Baer.
Out of the hundreds of handguns I've shot the LB was the only one that really put a smile on my face. It just "fit" and was more accurate than it needs to be.
