I just sent my P10C slide off to Jagerwerks for RMR slide milling. They offer the same service for the P-07 and Glocks at a pretty reasonable amount. Rather than going nuts on serrations and cuts I opted just for the RMR cut, dovetail for the rear BUIS, and a pocket cut on the top of the slide in front of the ejection port. The last request was purely for aesthetics. I thought about additional serrations on the front chamfer but in the end talked myself out of it since I?ve not had a problem racking the slide with the factory serrations.
Prior to the decision to add an RMR to this gun I added a HBi trigger, CGW guiderod so I could experiment with different spring weights, CWG striker, and Dawson fixed sights. I did shoot about 3K thru the gun to decide if I liked it enough to dump more $$ into it, including several USPSA and 3-gun matches. Added a TLR-1 HL for night stand and periodically when I shoot a night match.
Once the slide comes back with the RMR cuts I?m going to add Dawson front and Ameriglo rear iron sights, get some +5 extensions for the mag and thinking about shooting USPSA Carry Optics division with it (as well as night stand and CCW).
