I sent my TRP Operator to the Springfield Custom Shop around November last year, and just recently got it back. About half of the wait time was due to Ion-Bond, but it was worth it. Here is the build list, -Stan Chen Magwell installed and checkered 20lpi -Modify VZ grips for the magwell -High Cut Front Strap -Wilson Combat ambi safety -Blend factory grip safety (free) -Install Harrison rear sight to replace the factory adjustable -Install white outline front night sight -Harrison plunger tube -Harrison Long Trigger -Harrison slide stop -Harrison Extended mag release -Tool steel hammer sear and disconnector. -Carry Bevel (more than normal) -Ion Bond The trigger is set just under 5lbs, which is what I asked for. I took it out and put a few rounds through her today and it shot great. I can't wait to really wring her out. Over all I am very happy with the work that SACS did.
