Yeah, I had thought about a dovetail plate, but I feel like milling is probably my better long term option, especially for the lower bore axis and lower weight. It also looks like the hammer mods are out of the question. I had read some posts speculating on the Titan hammer for IDPA because it was used on some of the extreme series guns, but A.1.3.4 states
The extreme series of guns aren't IDPA legal.
It sounds like I'll best off sticking to the springs and the polishing. In the long term, I may look into a Stock II OR for USPSA, but I feel like the limited pro should still be a great gun for IDPA and a good one for USPSA, even without the bolo, hammer, etc. The big goal is to keep most of my training on the same gun and eliminate any inconsistencies I might encounter from frequently switching platforms.
