I've been using CR Speed for both my open and limited rig for quite a few years now and see no reason to change. If it ain't broke don't fix it. Good luck on your quest.
I've been shooting Para's for at least 20 yrs. both P-14 and P-16. Started with the P-14. I've run way in excess of 74K rds. including 180 PF for SOF matches. Still runs like a swiss watch. Don't shy away from Para, I've never had a problem. Good luck.
Keep in mind the 1050 does not come with the same guarantee as the other Dillon loaders as it's considered a commercial unit. Go with the 650, you'll never look back.
You can't beat MGM. Mike and Travis support the sport, make the best targets, and if you have a problem, which is very unlikely, take care of it , no questions asked.
My TruBor cracked in the same place. STI said they would replace it but I needed to send the gun in so they could fit the slide. They wouldn't just exchange the slide.
