After installing the new sear I got a chance to get a little shooting in. The sear alone is a very nice upgrade in enhancing the trigger overall for the $42 it costs and I retain the factory sear too. Installation was fairly easy other than taking apart any gun and especially new gun is a learning experience. That rear roll pin takes some good whacks to get it moving!
I also had loaded up a batch of Berry's 45 acp Target Hollow Points 200gr. Oddly they would not chamber? They dropped into my case gauge just fine, they shot fine in my friends Ruger 1911 and another 1911 that another shooter at the range had. It appears the bullet shoulder breaks to the straight of the base is scuffing and preventing proper seating. I have sent a message to Berry's and waiting a response back. The Target HP's shot very well in my S&W 625 revolver!

**Issue resolved, I loaded the bullets a bit too long, just needed to seat deeper as the bullet was hitting the lands/grooves before seating on case mouth.** Not an issue with the barrel, just the guy doing the reloads (me)

*Next I have a JMT sight pusher arriving, I will pull the the rear sight and polish the striker block button up real well and fully disassemble the rest of the gun to address any other areas I can find that show 'rub' to polish up. I have found that Wet/Dry sandpaper at 2000 grit makes for a good polishing medium and will do a fine job on polishing up feed ramps too
