Hey Jeff,
A bunch of us have put Volquartsen sears, extractors, and triggers on our 2245's (over on rimfirecentral) and think it makes a good pistol even better, I think much better. Many/most remove the mag safety too by using a Clark or similar (Sam Lam) hammer bushing. Have you, would you ever, run a test on such an animal? Because I got the sear from the "basement" sale, I think I put a total of $50 into my 2245. It is now (to me) fantastic. I'd love to get one of the new removable grip models and do the same thing.
Tom
