UPDATE: The very next day I field-stripped and thoroughly cleaned and lubed the Yukon and it still won't feed. I plunked my reloads in the barrel and they are perfect. I tested the extractor and it was a bit tight, so adjusted it and reinstalled. Still won't feed. So I then took apart my other Tisas and swapped extractors. Didn't help. I have tried multiple different magazines and loads, both factory and reloads. The only ammo it will reliably feed is .40 S&W. Weird. Open to suggestions.
First range trip with my new Tisas Yukon 2-Tone in 10mm. I also brought along my awesome Tisas D10 to verify any issues. Cleaned and lubed before the range trip, I brought both the factory mags and some new Wilson Combat 9-round mags.
I also brought a box of Federal 180gr brass factory ammo and another 100 rounds of two types of reloads to try.
First magazine of factory ammo was great, though hitting high.
Switched to reloads and SHTF. Seemed the more I shot, the worse the gun performed. It finally ended with factory ammo and factory magazines no longer functioning.
