Back in 2017 I was going to make the change to TDA from striker guns. I bought a PX4CC and signed up for a LTT Pistol Skills class that April. I bought extra mags, JMCK holsters and mag pouches, and lots of ammo.
I'll admit, the gun was slick - awesome action and very accurate for me. It also drew blood - hammer spur - which LTT started offering a bobbed version to resolve as I was far from the only one. Then, just maybe 2 weeks before the class, I found that my sweet spot for control and accuracy caused my XL hands to stall the slide out. That was no bueno. So, I tossed the previous investment to the side, dusted off the ol' G17.4 and rocked the class.
I sold that PX4CC off during the pandemic - made all my investment back plus a bit and still have the holsters/mag pouches should I ever be tempted to go down that path again. I seriously doubt I'd give it a go again, but one never knows.....
