Got to the range finally yesterday to try out my converted P365X (and also my new Glock G45 MOS) Shot up about 250 rounds between the two of a mix of Sig 115gr, Federal 115gr, Norma 124gr, Speer 124gr and Winchester 147gr. (I don't want to think about how much it's going to cost me to replace the ammo LOL)
Really glad I installed the XL grip frame on the 365. The extra length and the beavertail makes it much easier to control the recoil and get the sights back on target faster. I've had the gun for just over two years with about 500 rounds through with no failures of any kind.
Also very impressed with the performance of the Glock G45. Very good trigger out of the box, my guess about 5 lbs and very crisp with no over travel and short reset. Typical Glock sights but may be going to a red dot soon. Only issue was one FTE in the first magazine but I think it was caused by one of a few rounds of cheap leftover reman ammo I mixed in with the good stuff.
