Redcardinal I would PM member BMCM about changing out the hammer, trigger and sear on your 45CQB.
I thought long and hard before I changed mine. I am a shooter/accumulator, NOT a collector. So collector value on this rare gun wasnt a concern to me. I bought the gun from Grinder to use and it was a shooter grade when I got it, having been owned by another member here and a couple of other folks. It had some rounds down the pipe already.
There is also the fact that it is really a custom gun and a precision built one at that. Very few people left out there to work on it. BMCM is the only craftsman left that I would trust to do the job. Especially on a real Performance Center gun made in small numbers. He is currently repairing a shooter grade PC Shorty 45 MKII for me.
But I would encourage you to do it!
These guns were built to be shot. Make it what you want it to be. I did and Im very glad I did it while the opportunity existed. Good luck! Regards 18DAI
